<gpu_program>

Description

Allows to load and execute real time shaders written in GLSL.

Attributes

• name [STRING]: name of this XML node.
• filename [STRING]: location of the complete GLSL progam file.
• absolute_path [INTEGER]: absolute (1) or relative (0) path for the filename. - Default value = 0
• filename_vs [STRING]: location of a vertex shader file relative to the main XML script. Currently the vertex and pixel shaders must be in the same file.
• absolute_path_vs [INTEGER]: absolute (1) or relative (0) path for the filename_vs. - Default value = 0
• filename_ps [STRING]: location of a pixel shader file relative to the main XML script. Currently the vertex and pixel shaders must be in the same file.
• absolute_path_ps [INTEGER]: absolute (1) or relative (0) path for the filename_ps. - Default value = 0
• filename_gs [STRING]: location of a geometry shader file relative to the main XML script. Currently the vertex and pixel shaders must be in the same file.
• absolute_path_gs [INTEGER]: absolute (1) or relative (0) path for the filename_gs. - Default value = 0
• filename_tcs [STRING]: location of a tessellation control shader file relative to the main XML script. Currently the vertex and pixel shaders must be in the same file.
• absolute_path_tcs [INTEGER]: absolute (1) or relative (0) path for the filename_tcs. - Default value = 0
• filename_tes [STRING]: location of a tessellation evaluation shader file relative to the main XML script. Currently the vertex and pixel shaders must be in the same file.
• absolute_path_tes [INTEGER]: absolute (1) or relative (0) path for the filename_tes. - Default value = 0
• filename_cs [STRING]: location of a compute shader file relative to the main XML script. Currently the vertex and pixel shaders must be in the same file.
• absolute_path_cs [INTEGER]: absolute (1) or relative (0) path for the filename_cs. - Default value = 0
