| | '''OpenGL extension ARB.depth_buffer_float |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.ARB.depth_buffer_float to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension provides new texture internal formats whose depth |
| | components are stored as 32-bit floating-point values, rather than the |
| | normalized unsigned integers used in existing depth formats. |
| | Floating-point depth textures support all the functionality supported for |
| | fixed-point depth textures, including shadow mapping and rendering support |
| | via EXT_framebuffer_object. Floating-point depth textures can store |
| | values outside the range [0,1]. |
| | |
| | Additionally, this extension provides new packed depth/stencil pixel |
| | formats (see EXT_packed_depth_stencil) that have 64-bit pixels consisting |
| | of a 32-bit floating-point depth value, 8 bits of stencil, and 24 unused |
| | bites. A packed depth/stencil texture internal format is also provided. |
| | |
| | This extension does not provide support for WGL or GLX pixel formats with |
| | floating-point depth buffers. The existing (but not commonly used) |
| | WGL_EXT_depth_float extension could be used for this purpose. |
| | |
