OpenGL Information Center |
---|
The OpenGL Information Center supplies lots of information an OpenGL developer (both C/C++ and Tcl) needs.
Information about installed OpenGL driver
The GL information category shows general informations about the installed OpenGL and Tcl3D versions.
Information about OpenGL extensions
The GL extensions category shows the following information about each OpenGL extension:
- Information about availability on underlying hardware and driver.
- Information about availability with used GLEW version.
Information about OpenGL core and extension functions
The GL commands category shows the following information about each OpenGL function:
- Availability on underlying hardware and driver.
- Corresponding OpenGL version or extension.
- Deprecated since OpenGL version (0.0 means not deprecated).
- Signature of function (both in C and Tcl).
- URL of official documentation page.
Information about OpenGL core and extension enumerations
The GL enums category shows the following information about each OpenGL enumeration:
- Decimal value.
- Hexadecimal value.
- Corresponding OpenGL version or extension.
Information about OpenGL versions and extensions
The Version infos tab shows the following information about each OpenGL version or extension:
- List of corresponding functions.
- List of corresponding enumerations.
File check
The Check File tab allows to load OpenGL source files (C or Tcl) into a text widget.
The following information about the file is provided:
- List of used OpenGL functions.
- List of used OpenGL enumerations.
History
All visited tables are held in a history for easy re-access.
Export functionality

Module tcl3dOgl: Sub-module Togl
This module is an enhanced version of the Togl widget, a Tk canvas for displaying OpenGL graphics.
The following enhancements are currently implemented:
- Callback functions in Tcl.
- Better bitmap font support.
- Multisampling support.
- Swap Interval support.
- OpenGL Core and Compatibility profile support.
Requirements for this module: None, all files are contained in the Tcl3D distribution.
The original Togl widget is copyrighted by Brian Paul and Benjamin Bederson and distributed under the BSD license.
See the Togl homepage
for detailed license information.
The modified Tcl3D version of Togl is copyrighted by Paul Obermeier and distributed under the BSD license.
Module tcl3dOgl: Sub-module OpenGL
This module wraps OpenGL functionality up to OpenGL Version 4.6, the GLU library functions based on Version 1.2 and most of the available OpenGL extensions.
It is implemented with the help of the GLEW library.
Standard shapes (box, sphere, cylinder, teapot, ...) with a GLUT compatible syntax are supplied here, too.
Requirements for this module: An OpenGL compatible library. OpenGL header files are contained in the Tcl3D distribution.
The GLEW library is distributed under a modified BSD license. See the GLEW Copyright and Licensing page for detailed license information.
The original GLUT shape code is copyrighted by Mark Kilgard. It is not in the public domain, but freely distributable. See the GLUT homepage for detailed license information.
Module tcl3dOgl: Sub-module Util
This module implements C/C++ and Tcl utilities offering functionality needed for 3D programs. It currently contains the following modules:
- 3D vector and transformation matrix module.
- Information module.
- File utility module.
- Color names module.
- Large data module (tcl3dVector).
- Image utility module.
- Screen capture module.
- Timing module.
- Random number module.
- 3D-model and shapes module.
- Virtual track- and arcball module.
- C/C++ based utility functions for some of the demo applications.
Requirements for this module: None, all files are contained in the Tcl3D distribution.
