The FAQ has been split into 4 parts.

Part 1 is an index of questions.

Part 2 are general questions about OpenGL documentation, implementations,

       licensing, and other general product information.

Part 3 is about OpenGL governance and the ARB.

Part 4 are technical questions, including where source code examples

       can be found.

----- Part 2

Q_2_01:  How do I submit changes or additions to this FAQ?

Q_2_02:  What is OpenGL?

Q_2_03:  Where are World Wide Web sites with information about OpenGL?

Q_2_04:  What does the .gl or .GL file format have to do with OpenGL?

Q_2_05:  What documentation is available for OpenGL?  (A bibliography of

         OpenGL documents is listed here.)

Q_2_06:  Where can I get the OpenGL specification?

Q_2_07:  Which vendors are licensing OpenGL?

Q_2_08:  What OpenGL implementations are available?

Q_2_09:  Does Windows 95 support OpenGL?

Q_2_10:  What interest is there for OpenGL in Japan?

----- Part 3

Q_3_01:  Who needs to license OpenGL?  Who doesn't?

Q_3_02:  What are the conformance tests?

Q_3_03:  What is Silicon Graphics policy on "free"

         implementations of APIs which resemble the OpenGL API?

Q_3_04:  What is Mesa 3D and where can I get it?

Q_3_05:  How does a university or research institution acquire access to

         OpenGL source code?

Q_3_06:  How is a commercial license acquired?

Q_3_07:  How is the OpenGL governed? Who decides what changes can be made?

Q_3_08:  Who are the current ARB members?

Q_3_09:  What is the philosophy behind the structure of the ARB?

Q_3_10:  How does the OpenGL ARB operate logistically? When does the

         ARB have meetings?

Q_3_11:  How do additional members join the OpenGL ARB?

Q_3_12:  So if I'm not a member of the ARB, am I shut out of the decision

         making process?

Q_3_13:  Are ARB meetings open to observers?

Q_3_14:  What benchmarks exist for OpenGL?

----- Part 4

Q_4_01:  Where can I find OpenGL source code examples?

         For instance, where is an example which combines OpenGL with Motif,

         using the Motif widget?

Q_4_02:  How do I contribute OpenGL code examples to a publicly accessible

         archive?

Q_4_03:  What is the GLUT toolkit?  Where do I get it?

Q_4_04:  What is the relationship between IRIS GL and OpenGL?

         Is OpenGL source code or binary code compatible with IRIS GL?

Q_4_05:  Why should I port my IRIS GL application to OpenGL?

Q_4_06:  How much work is it to convert an IRIS GL program to OpenGL?

         What are the major differences between them?

Q_4_07:  When using Xlib, how do I create a borderless window?

Q_4_08:  How do I switch between single buffer and double buffer mode?

Q_4_09:  On my machine, it appears that glXChooseVisual is only able to

         match double-buffered visuals. I want to have more bits of color

         resolution, so how do I render in single buffer mode?

Q_4_10:  I've got a 24-bit machine, but my OpenGL windows are not using

         the full color resolution.  What's wrong?  My program looks fine

         on one machine, but the depth buffer doesn't work on another.

         What's wrong?

Q_4_11:  What information is available about OpenGL extensions?

Q_4_12:  How do I make shadows in OpenGL?

Q_4_13:  How can I use 16 bit X fonts?

Q_4_14:  What's in the new GLU 1.2 tesselator?

Q_4_15:  Why is my glDrawPixels (or glCopyPixels or glReadPixels) slow?

Q_4_16:  How can I used OpenGL with Tcl/Tk?
