test.pl - Bob Free

This test app is used by the POGL build process to validate a successful POGL build.

It provides an example of a number of POGL features:

• Listing installed/implemented OpenGL extensions
• Testing for supported extensions
• GLUT rendering, menus and keyboard handling
• Object transformations
• Orthogonal text rendering
• OpenGL::Array objects
• OpenGL::Image objects
• Surface color and texture mapping
• Mipmap textures
• Frame Buffer Object (FBO) extension
• Vertex Buffer Object (VBO) extension
• GPU/Memory-mapped operations
• Vertex and Fragment Programs
• ImageMagick interoperability
• Loading/saving textures

ogl_bench.pl - Bob Free

This app was used to benchmark Perl vs C OpenGL perfromance.

It demonstrates rendering to an FBO buffer in GPU memory, then using this as a texture to render other surfaces.

It also provides a simple (and somewhat interesting) Black Light shader.
