-<h1>1. Introduction</h1>
-<p>The Mini GLX interface facilitates OpenGL rendering on embedded
-devices. The interface is a subset of the GLX interface, plus a minimal
-set of Xlib-like functions.</p>
-<p>Programs written to the Mini GLX specification should run unchanged
-on systems with the X Window System and the GLX extension. The intention
-is to allow flexibility for prototyping and testing.</p>
-<p>This document serves as both the reference guide and programming
-guide for Mini GLX.<br>
-<br>
-</p>
-<h1>2. Mini GLX Concepts</h1>
-<p>The OpenGL specification does not describe how OpenGL rendering
-contexts and drawing surfaces (i.e. the frame buffer) are created and
-managed. Rather, this is handled by an OpenGL window system interface,
-such as Mini GLX.</p>
-<p>There are three main datatypes or resources managed by Mini GLX. The
-resources and their corresponding GLX or Xlib data types are:</p>
-<table cellspacing="10" align="center">
- <tbody>
- <tr>
- <td><u>Resource</u></td>
- <td><u>Data type</u></td>
- </tr>
- <tr>
- <td>pixel formats</td>
- <td>X Visual and XVisualInfo</td>
- </tr>
- <tr>
- <td>drawing surfaces</td>
- <td>X Window or GLXDrawable</td>
- </tr>
- <tr>
- <td>rendering contexts</td>
- <td>GLXContext</td>
- </tr>
- </tbody>
-</table>
-<p>Pixel formats or X Visuals describe the per-pixel attributes of the
-frame buffer. For example, bits per color component, Z buffer size,
-stencil size, TrueColor vs PseudoColor, etc.</p>
-<p>Drawing surfaces or X Windows typically describe a spatial
-allocation of the frame buffer (i.e. the position and size of a
-rectangular region of pixels). Since MiniGLX doesn't really support a
-window system, the window is effectively the entire frame buffer.</p>
-<p>A rendering context represents the current OpenGL state such as
-current drawing color, line width, blending mode, texture parameters,
-etc. Several rendering contexts can be created but only one can be in
-use at any given time.</p>
-<p>The Mini GLX interface provides all the functions needed for
-choosing pixel formats, create drawing surfaces, creating rendering
-contexts and binding rendering contexts to drawing surfaces.<br>
-<br>
-</p>
-<h1>3. Using Mini GLX</h1>
-<p>To use the Mini GLX interface in your application, include the
-GL/miniglx.h header file at compile time:</p>
-<blockquote><code> #include <GL/miniglx.h><br>
- </code></blockquote>
-<code></code>Applications should link with libGL.so (i.e. <code>gcc
-myprogram.o -lGL -o myprogram</code>). libGL.so implements the
-MiniGLX API functions and, in turn, loads a hardware-specific device
-driver (such as <code>radeon_dri.so</code>) at runtime. The
-environment variable <code>LIBGL_DRIVERS_PATH</code> should name the
-directory where these modules are located.<br>
-<br>
-The remainder of this section describes the MiniGLX API functions.<br>
-<br>
-<h2>3.1 Initialization</h2>
-<p>The XOpenDisplay function is used to initialize the graphics system:</p>
-<blockquote>
- <pre>Display *XOpenDisplay(const char *displayname)<br></pre>
-</blockquote>
-<p>The <code>displayName</code> parameter is currently ignored in Mini
-GLX. It is recommended that <code>NULL</code> be passed as the<code>displayName</code>
-parameter.</p>
-<p>If XOpenDisplay is able to initialize the graphics system a pointer
-to a Display will be returned. Otherwise, NULL will be returned.</p>
-<h2>3.2 Choosing a Visual</h2>
-<p>A visual (i.e. pixel format) must be chosen before a drawing surface
-or rendering context can be created. This is done with the
-glXChooseVisual function:</p>
-<blockquote>
- <pre>XVisualInfo *glXChooseVisual(Display *dpy, int screen, const int *attribList)<br></pre>
-</blockquote>
-<p><code>dpy</code> is a pointer to the display returned by
-XOpenDisplay. </p>
-<p><code>screen</code> is currently ignored by Mini GLX and should be
-zero. </p>
-<p><code>attribList</code> is a list of GLX attributes which describe
-the desired pixel format. It is terminated by the token <code>None</code>.
-The attributes are as follows:</p>
-<blockquote>
- <dl>
- <dt><code>GLX_USE_GL</code></dt>
- <dd>This attribute should always be present in order to maintain
-compatibility with GLX.</dd>
- <dt><code>GLX_RGBA</code></dt>
- <dd>If present, only RGBA pixel formats will be considered.
-Otherwise, only color index formats are considered.</dd>
- <dt><code>GLX_DOUBLEBUFFER</code></dt>
- <dd>if present, only double-buffered pixel formats will be chosen.</dd>
- <dt><code>GLX_RED_SIZE n</code></dt>
- <dd>Must be followed by a non-negative integer indicating the
-minimum number of bits per red pixel component that is acceptable.</dd>
- <dt><code>GLX_GREEN_SIZE n</code></dt>
- <dd>Must be followed by a non-negative integer indicating the
-minimum number of bits per green pixel component that is acceptable.</dd>
- <dt><code>GLX_BLUE_SIZE n</code></dt>
- <dd>Must be followed by a non-negative integer indicating the
-minimum number of bits per blue pixel component that is acceptable.</dd>
- <dt><code>GLX_ALPHA_SIZE n</code></dt>
- <dd>Must be followed by a non-negative integer indicating the
-minimum number of bits per alpha pixel component that is acceptable.</dd>
- <dt><code>GLX_STENCIL_SIZE n</code></dt>
- <dd>Must be followed by a non-negative integer indicating the
-minimum number of bits per stencil value that is acceptable.</dd>
- <dt><code>None</code></dt>
- <dd>This token is used to terminate the attribute list.</dd>
- </dl>
-</blockquote>
-<p>glXChooseVisual will return a pointer to an XVisualInfo object which
-most closely matches the requirements of the attribute list. If there
-is no visual which matches the request, NULL will be returned.</p>
-<p>Note that visuals with accumulation buffers and depth buffers are
-not available.<br>
-<br>
-</p>
-<h2>3.3 Creating a Drawing Surface</h2>
-<p>Drawing surfaces are created as X windows. For Mini GLX,
-windows are <i>full-screen</i>; they cover the entire frame buffer.
- Also, Mini GLX imposes a limit of one window. A second window
-cannot be created until the first one is destroyed.</p>
-<h3>3.3.1 Window Creation</h3>
-<p>The XCreateWindow function is used to create a drawing surface:</p>
-<blockquote>
- <pre>Window XCreateWindow( Display *display,<br> Window parent,<br> int x, int y,<br> unsigned int width, unsigned int height,<br> unsigned int borderWidth,<br> int depth,<br> unsigned int class,<br> Visual *visual,<br> unsigned long valuemask,<br> XSetWindowAttributes *attributes )<br></pre>
-</blockquote>
-<p>The parameters are as follows:</p>
-<blockquote>
- <dl>
- <dt><code>display</code></dt>
- <dd>A Display pointer, as returned by XOpenDisplay.</dd>
- <dt><code>parent</code></dt>
- <dd>The parent window for the new window. For Mini GLX, this
-should be<code>RootWindow(dpy, 0)</code>.</dd>
- <dt><code>x, y</code></dt>
- <dd>The position of the window. For Mini GLX, both values should
-be zero.</dd>
- <dt><code>width, height</code></dt>
- <dd>The size of the window. For Mini GLX, this specifies the
-desired screen size such as 1024, 768 or 1280, 1024.</dd>
- <dt><code>borderWidth</code></dt>
- <dd>This parameter should be zero.</dd>
- <dt><code>depth</code></dt>
- <dd>The pixel depth for the window. For Mini GLX this should be
-the depth found in the XVisualInfo object returned by <code>glxChooseVisual</code>.</dd>
- <dt><code>class</code></dt>
- <dd>The window class. For Mini GLX this value should be <code>InputOutput</code>.</dd>
- <dt><code>visual</code></dt>
- <dd>This parameter should be the <code>visual</code> field of the <code>XVisualInfo</code>
-object returned by <code>glxChooseVisual</code>.</dd>
- <dt><code>valuemask</code></dt>
- <dd>This parameter indicates which fields of the <code>XSetWindowAttributes</code>
-are to be used. For Mini GLX this is typically the bitmask<code>CWBackPixel
-| CWBorderPixel | CWColormap</code>.</dd>
- <dt><code>attributes</code></dt>
- <dd>Initial window attributes. Of the fields in the <code>XSetWindowAttributes</code>
-structure, the<code>background_pixel</code>, <code>border_pixel</code>
-and <code>colormap</code> fields should be set. See the discussion
-below regarding colormaps.</dd>
- </dl>
-</blockquote>
-<p><code>XCreateWindow</code> will return a window handle if it succeeds
-or zero if it fails.</p>
-<h3>3.3.2 Window Mapping</h3>
-<p>To display the window the XMapWindow function must be called:</p>
-<blockquote>
- <pre>void XMapWindow(Display *dpy, Window w)</pre>
-</blockquote>
-<p>This function does nothing in Mini GLX but is required for Xlib/GLX
-compatibility</p>
-<h3>3.3.3 Colormaps<br>
-</h3>
-<p>Xlib requires specification of a colormap when creating a window.
- For purposes of interoperability, Mini GLX requires this as well,
-though the colormap is not actually used. The XCreateColormap
-function is used to create a colormap:</p>
-<blockquote><code>Colormap XCreateColormap(Display *dpy, Window window,
-Visual *visual, int alloc)</code><br>
- <code></code></blockquote>
-<p>The parameters are as follows:<br>
-</p>
-<blockquote>
- <dl>
- <dt><code>dpy</code></dt>
- <dd>The display handle as returned by XOpenDisplay.</dd>
- <dt><code>window</code></dt>
- <dd> This parameter is ignored by Mini GLX but should be the value
-returned by the <code>RootWindow(dpy, 0)</code> macro.<br>
- </dd>
- <dt><code>visual</code></dt>
- <dd>This parameter is ignored by Mini GLX but should be the visual
-field of the XVisualInfo object returned by glXChooseVisual. </dd>
- <dt><code>alloc</code></dt>
- <dd>This parameter is ignored by Mini GLX but should be set to <code>AllocNone</code>.</dd>
- </dl>
-</blockquote>
-<br>
-<h2>3.4 Creating a Rendering Context</h2>
-<p>An OpenGL rendering context is created with the <code>glXCreateContext</code>
-function:</p>
-<blockquote>
- <pre>GLXContext glXCreateContext(Display *dpy, XVisualInfo *visInfo, GLXContext shareList, Bool direct)<br></pre>
-</blockquote>
-<p>The parameters are as follows:</p>
-<blockquote>
- <dl>
- <dt><code>dpy</code></dt>
- <dd>The display handle as returned by XOpenDisplay.</dd>
- <dt><code>visInfo</code></dt>
- <dd>The visual as returned by glXChooseVisual.</dd>
- <dt><code>shareList</code></dt>
- <dd>If non-zero, texture objects and display lists are shared with
-the named rendering context. If zero, texture objects and display lists
-will (initially) be private to this context. They may be shared when a
-subsequent context is created.</dd>
- <dt><code>direct</code></dt>
- <dd>Specifies whether direct or indirect rendering is desired. For
-Mini GLX this value is ignored but it should be set to <code>True</code>.</dd>
- </dl>
-</blockquote>
-<p><code>glXCreateContext</code> will return a GLXContext handle if it
-succeeds or zero if it fails due to invalid parameter or insufficient
-resources.<br>
-<br>
-</p>
-<h2>3.5 Binding a Rendering Context</h2>
-<p>The final step before beginning OpenGL rendering is to bind (i.e.
-activate) a rendering context and drawing surface with the
-glXMakeCurrent function:</p>
-<blockquote>
- <pre>Bool glXMakeCurrent(Display *dpy, GLXDrawable drawable, GLXContext ctx)<br></pre>
-</blockquote>
-<p>The parameters are as follows:</p>
-<blockquote>
- <dl>
- <dt><code>dpy</code></dt>
- <dd>The display handle, as returned by XOpenDisplay.</dd>
- <dt><code>drawable</code></dt>
- <dd>The window or drawable to bind to the rendering context. This
-should be the value returned by XCreateWindow.</dd>
- <dt><code>ctx</code></dt>
- <dd>The rendering context to bind, as returned by glXCreateContext.</dd>
- </dl>
-</blockquote>
-<p>If glXMakeCurrent succeeds True is returned. Otherwise False is
-returned to indicate an invalid display, window or context parameter.</p>
-<p>After the rendering context has been bound to the drawing surface
-OpenGL rendering can begin.</p>
-<p>The current rendering context may be unbound by calling
-glXMakeCurrent with the window and context parameters set to zero.</p>
-<p>An application may create any number of rendering contexts and bind
-them as needed. Note that binding a rendering context is generally not a
-light-weight operation. Most simple OpenGL applications create
-only one rendering context.<br>
-<br>
-</p>
-<h2>3.6 Color Buffer Swapping</h2>
-<p>A double buffered window has two color buffers: a front buffer and a
-back buffer. Normally, rendering is directed to the back buffer while
-the front buffer is displayed. When rendering of a frame is finished
-the front and back buffers are swapped to provide the illusion of
-instanteous screen updates.</p>
-<p>The color buffers for a particular window (i.e. drawable) may be
-swapped with the glXSwapBuffers command:</p>
-<blockquote>
- <pre>void glXSwapBuffers(Display *dpy, GLXDrawable drawable)<br></pre>
-</blockquote>
-Any pending rendering commands will be completed before the buffer swap
-takes place.<br>
-<br>
-Calling glXSwapBuffers on a window which is single-buffered has no
-effect.<br>
-<br>
-<h2>3.7 Releasing Resources</h2>
-<h3>3.7.1 Releasing Rendering Contexts</h3>
-<p>A rendering context may be destroyed by calling glXDestroyContext:</p>
-<blockquote>
- <pre>void glXDestroyContext(Display *dpy, GLXContext ctx)<br></pre>
-</blockquote>
-<h3>3.7.2 Releasing Windows</h3>
-<p>A window may be destroyed by calling XDestroyWindow:</p>
-<blockquote>
- <pre>void XDestroyWindow(Display *dpy, Window window)<br></pre>
-</blockquote>
-<h3>3.7.3 Releasing Visuals</h3>
-<p>An XVisualInfo object may be freed by calling XFree:</p>
-<blockquote>
- <pre>void XFree(void *data)<br></pre>
-</blockquote>
-<h3>3.7.4 Releasing Colormaps</h3>
-<p>A colormap may be freed by calling XFreeColormap:</p>
-<blockquote>
- <pre>void XFreeColormap(Display *dpy, Colormap colormap)<br></pre>
-</blockquote>
-<h3>3.7.4 Releasing Display Resources</h3>
-<p>When the application is about to exit, the resources associated with
-the graphics system can be released by calling XCloseDisplay:</p>
-<blockquote>
- <pre>void XCloseDisplay(Display *dpy)<br></pre>
-</blockquote>
-<p>The display handle becomes invalid at this point.<br>
-<br>
-</p>
-<h2>3.8 Query Functions</h2>
-<h3>3.8.1 Querying Available Visuals</h3>
-A list of all available visuals can be obtained with the XGetVisualInfo
-function:<br>
-<br>
-<div style="margin-left: 40px;"><code>XVisualInfo
-*XGetVisualInfo(Display *dpy, long vinfo_mask, XVisualInfo
-*vinfo_template, int *nitems_return)<br>
-</code></div>
-<br>
-The parameters are as follows:<br>
-<blockquote>
- <dl>
- <dt><code>dpy</code></dt>
- <dd>The display handle, as returned by XOpenDisplay.</dd>
- <dt><code>vinfo_mask</code></dt>
- <dd>A bitmask indicating which fields of the vinfo_template are to
-be matched. The value must be VisualScreenMask.</dd>
- <dt><code>vinfo_template</code></dt>
- <dd>A template whose fields indicate which visual attributes must
-be matched by the results. The screen field of this structure must
-be zero.</dd>
- <dt><code>nitems_return</code></dt>
- <dd>Returns the number of visuals returned. </dd>
- </dl>
-</blockquote>
-The return value is the address of an array of all available visuals.<br>
-<br>
-An example of using XGetVisualInfo to get all available visuals follows:<br>
-<br>
-<div style="margin-left: 40px;"><code>XVisualInfo visTemplate, *results;</code><br>
-<code>int numVisuals;</code><br>
-<code>Display *dpy = XOpenDisplay(NULL);</code><br>
-<code>visTemplate.screen = 0;</code><br>
-<code>results = XGetVisualInfo(dpy, VisualScreenMask, &visTemplate,
-&numVisuals);</code><br>
-<code></code></div>
-<br>
-<h3>3.8.2 Querying Visual Attributes</h3>
-<p>The GLX attributes of an X visual may be queried with the
-glXGetConfig function:</p>
-<blockquote>
- <pre>int glXGetConfig(Display *dpy, XVisualInfo *vis, int attribute, int *value)<br></pre>
-</blockquote>
-<p>The parameters are as follows:</p>
-<blockquote>
- <dl>
- <dt><code>dpy</code></dt>
- <dd>The display handle, as returned by XOpenDisplay.</dd>
- <dt><code>vis</code></dt>
- <dd>The visual, as returned by glXChooseVisual.</dd>
- <dt><code>attribute</code></dt>
- <dd>The attribute to query. The attributes are listed below.</dd>
- <dt><code>value</code></dt>
- <dd>Pointer to an integer in which the result of the query will be
-stored. </dd>
- </dl>
-</blockquote>
-<p>The return value will be zero if no error occurs.<code>
- GLX_INVALID_ATTRIBUTE</code> will be returned if the attribute
-parameter is invalid.<code> GLX_BAD_VISUAL</code> will be returned
-if the XVisualInfo parameter is invalid.</p>
-<p>The following attributes may be queried:</p>
-<blockquote>
- <dl>
- <dt><code>GLX_USE_GL</code></dt>
- <dd>The result will be <code>True</code> or <code>False</code> to
-indicate if OpenGL rendering is supported with the visual. Mini GLX
-always return <code>True</code>.</dd>
- <dt><code>GLX_RGBA</code></dt>
- <dd>The result will be <code>True</code> for RGBA visuals or <code>False</code>
-for color index visuals.</dd>
- <dt><code>GLX_DOUBLEBUFFER</code></dt>
- <dd>The result will be <code>True</code> if the visual has two
-color buffers or <code>False</code> if the visual has one color buffer.</dd>
- <dt><code>GLX_RED_SIZE</code></dt>
- <dd>The result will be the number of red bits per pixel.</dd>
- <dt><code>GLX_GREEN_SIZE</code></dt>
- <dd>The result will be the number of green bits per pixel.</dd>
- <dt><code>GLX_BLUE_SIZE</code></dt>
- <dd>The result will be the number of blue bits per pixel.</dd>
- <dt><code>GLX_ALPHA_SIZE</code></dt>
- <dd>The result will be the number of alpha bits per pixel.</dd>
- <dt><code>GLX_DEPTH_SIZE</code></dt>
- <dd>The result will be the number of bits per Z value.</dd>
- <dt><code>GLX_STENCIL_SIZE</code></dt>
- <dd>The result will be the number of bits per stencil value.<br>
- <br>
- </dd>
- </dl>
-</blockquote>
-<h3>3.8.3 Querying the Current Rendering Context</h3>
-<p>The current rendering context can be queried with
-glXGetCurrentContext: </p>
-<blockquote>
- <pre>GLXContext glXGetCurrentContext(void)<br></pre>
-</blockquote>
-<p>Zero will be returned if no context is currently bound.<br>
-<br>
-</p>
-<h3>3.8.4 Querying the Current Drawable</h3>
-<p>The current drawable (i.e. window or drawing surface) can be queried
-with glXGetCurrentDrawable:</p>
-<blockquote>
- <pre>GLXDrawable glXGetCurrentDrawable(void)<br></pre>
-</blockquote>
-<p>Zero will be returned if no drawable is currently bound.<br>
-<br>
-</p>
-<h3>3.8.5 Function Address Queries</h3>
-<p>The glXGetProcAddress function will return the address of any
-available OpenGL or Mini GLX function:</p>
-<blockquote>
- <pre>void *glXGetProcAddress(const GLubyte *procName)<br></pre>
-</blockquote>
-<p>If <code>procName</code> is a valid function name, a pointer to that
-function will be returned. Otherwise, NULL will be returned.</p>
-<p>The purpose of glXGetProcAddress is to facilitate using future
-extensions to OpenGL or Mini GLX. If a future version of the library
-adds new extension functions they'll be accessible via
-glXGetProcAddress. The alternative is to hard-code calls to the new
-functions in the application but doing so will prevent linking the
-application with older versions of the library.<br>
-<br>
-</p>
-<h2>3.9 Versioning</h2>
-The Mini GLX version can be queried at run time with glXQueryVersion:
-<blockquote>
- <pre>Bool glXQueryVersion(Display *dpy, int *major, int *minor)<br></pre>
-</blockquote>
-<p><code>major</code> will be set to the major version number and<code>minor</code>
-will be set to the minor version number.<code>True</code> will be
-returned if the function succeeds. <code>False</code> will be returned
-if the function fails due to invalid parameters. The <code>dpy</code>
-argument is currently ignored, but should be the value returned by
-XOpenDisplay.</p>
-<p>At compile time, the Mini GLX interface version can be tested with
-the MINI_GLX_VERSION_1_<i>x</i> preprocessor tokens. For example, if
-version 1.0 of Mini GLX is supported, then<code> MINI_GLX_VERSION_1_0</code>
-will be defined. If version 1.1 of Mini GLX is supported, then<code>
-MINI_GLX_VERSION_1_1</code> will be defined.</p>
-<p>At the time of writing the current Mini GLX version is 1.0.<br>
-<br>
-</p>
-<h1>4.0 Interoperability with GLX and Xlib</h1>
-While Mini GLX strives to be compatible with GLX and Xlib there are
-some unavoidable differences which must be taken into consideration.<br>
-<h2>4.1 Public vs Private Structures</h2>
-The structure of many X data types is public. For example, the <code>Display</code>
-data type is defined as a structure in /usr/include/X11/Xlib.h and
-programmers may access any fields of that structure at will. Mini
-GLX also defines a Display data type but its fields are hidden and not
-visiblein <code>miniglx.h</code>. Duplicating the Xlib
-declaration for the <code>Display</code> data type in minigl.h would
-require defining a large number of other superfluous Xlib datatypes.<br>
-<br>
-Mini GLX users are discouraged from directly accessing the fields of
-Xlib data types to maximize portability - though this is unavoidable to
-some extent. For example, the <code>XVisualInfo</code> and <code>XSetWindowAtttributes</code>
-data types must be completely public.
-<h2>4.2 Macros</h2>
-In some cases, Xlib defines macros which are meant to be used instead
-of direct structure accesses. For example, the <code>RootWindow(dpy,
-screen)</code> macro returns the root window for a given screen on a
-given display. Unfortunately, macros do nothing to aid in ABI
-compatibility since they are resolved at compile time instead of at
-link/run time.<br>
-<br>
-Mini GLX also defines a <code>RootWindow</code> macro since it's
-essential for creating windows. But the implementation of this
-macro by Xlib and Mini GLX is completely different.<br>
-<h2>4.3 Summary</h2>
-Because Xlib and Mini GLX define data types and macros differently,
-Mini GLX applications must be recompiled when retargeting Mini GLX or
-native Xlib/GLX. That is, applications can't simply be re-linked
-because of ABI incompatibilities.<br>
-<br>
-Nevertheless, the fact that Mini GLX programs can be recompiled for
-Xlib and GLX increases portability and flexibility for testing and
-prototyping.<br>
-<br>
-<h1>5.0 Example Program</h1>
-<p>This section shows an example program which uses the Mini GLX
-interface. The program simply draws several frames of a rotating square.<br>
-</p>
-<p>The program may be compiled for use with Xlib/GLX or Mini GLX by
-setting the <code>USE_MINIGLX</code> token to 0 or 1, respectively.
- Note that the only difference is the header files which are
-included.<br>
