| | '''OpenGL extension NV.geometry_shader4 |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.NV.geometry_shader4 to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension builds upon the EXT_geometry_shader4 specification to |
| | provide two additional capabilities: |
| | |
| | * Support for QUADS, QUAD_STRIP, and POLYGON primitive types when |
| | geometry shaders are enabled. Such primitives will be tessellated |
| | into individual triangles. |
| | |
| | * Setting the value of GEOMETRY_VERTICES_OUT_EXT will take effect |
| | immediately. It is not necessary to link the program object in |
| | order for this change to take effect, as is the case in the EXT |
| | version of this extension. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/NV/geometry_shader4.txt |
