GPU Shader (gpu.shader)¶
This module provides access to GPUShader internal functions.
Built-in shaders
All built-in shaders have the mat4 ModelViewProjectionMatrix uniform.
The value of it can only be modified using the gpu.matrix module.

gpu.shader.code_from_builtin(shader_name)¶ Exposes the internal shader code for query.
- Parameters
shader_name (str) –
One of these builtin shader names:
2D_UNIFORM_COLOR2D_FLAT_COLOR2D_SMOOTH_COLOR2D_IMAGE3D_UNIFORM_COLOR3D_FLAT_COLOR3D_SMOOTH_COLOR
- Returns
Vertex, fragment and geometry shader codes.
- Return type
dict
-
gpu.shader.from_builtin(shader_name)¶ Shaders that are embedded in the blender internal code. They all read the uniform
mat4 ModelViewProjectionMatrix, which can be edited by thegpu.matrixmodule. For more details, you can check the shader code with thegpu.shader.code_from_builtin()function.- Parameters
shader_name (str) –
One of these builtin shader names:
2D_UNIFORM_COLOR2D_FLAT_COLOR2D_SMOOTH_COLOR2D_IMAGE3D_UNIFORM_COLOR3D_FLAT_COLOR3D_SMOOTH_COLOR
- Returns
Shader object corresponding to the given name.
- Return type
bpy.types.GPUShader
-
gpu.shader.unbind()¶ Unbind the bound shader object.
