| '''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 |
