Detailed Description

Uniform buffers API. Used to handle many uniforms update at once. Make sure that the data structure is compatible with what the implementation expect. (see "7.6.2.2 Standard Uniform Block Layout" from the OpenGL spec for more info about std140 layout) Rule of thumb: Padding to 16bytes, don't use vec3, don't use arrays of anything that is not vec4 aligned.

◆ GPU_uniformbuf_create_from_list()

blender::gpu::UniformBuf * GPU_uniformbuf_create_from_list	(	ListBase *	inputs,

Parameters

inputs ListBase of BLI_genericNodeN(GPUInput).

Returns: nullptr if failed to create or if inputs is empty.
