Blender: blender::gpu::GLVaoCache Class Reference

Blender V2.93

#include <gl_batch.hh>

Vao cache
Each #GLBatch has a small cache of VAO objects that are used to avoid VAO reconfiguration. TODO(fclem): Could be revisited to avoid so much cross references.

◆ base_instance_vao_get()

GLuint GLVaoCache::base_instance_vao_get	(	GPUBatch *	batch,
		int	i_first
	)

There seems to be a nasty bug when drawing using the same VAO reconfiguring (T71147). We just use a throwaway VAO for that. Note that this is likely to degrade performance.
