| | '''OpenGL extension EXT.bindable_uniform |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.EXT.bindable_uniform to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension introduces the concept of bindable uniforms to the OpenGL |
| | Shading Language. A uniform variable can be declared bindable, which |
| | means that the storage for the uniform is not allocated by the |
| | compiler/linker anymore, but is backed by a buffer object. This buffer |
| | object is bound to the bindable uniform through the new command |
| | UniformBufferEXT(). Binding needs to happen after linking a program |
| | object. |
| | |
| | Binding different buffer objects to a bindable uniform allows an |
| | application to easily use different "uniform data sets", without having to |
| | re-specify the data every time. |
| | |
| | A buffer object can be bound to bindable uniforms in different program |
| | objects. If those bindable uniforms are all of the same type, accessing a |
| | bindable uniform in program object A will result in the same data if the |
| | same access is made in program object B. This provides a mechanism for |
| | 'environment uniforms', uniform values that can be shared among multiple |
| | program objects. |
