blender::gpu::GLVaoCache Class Reference

#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.
	GLVaoCache ()
	~GLVaoCache ()

GLuint	lookup (const GLShaderInterface *interface)
void	insert (const GLShaderInterface *interface, GLuint vao_id)
void	remove (const GLShaderInterface *interface)
void	clear ()

Detailed Description

VAO management: remembers all geometry state (vertex attribute bindings & element buffer) for each shader interface. Start with a static number of VAO's and fallback to dynamic count if necessary. Once a batch goes dynamic it does not go back.
