Function Documentation

createPbrInstancedStateGroup()

vsg::ref_ptr< vsg::StateGroup > chrono::vsg3d::createPbrInstancedStateGroup	(	vsg::ref_ptr< const vsg::Options >	options,
		std::shared_ptr< ChVisualMaterial >	material,
		bool	double_faced = false
	)

Create a state group for PBR shapes drawn as GPU instances with vsg::InstanceDrawIndexed.

The pipeline takes vertex positions and normals per vertex, and colors, translations, rotations, and scales per instance (from the vsg::InstanceNode above the draw command). The instance colors replace the diffuse color of the material; all other material properties apply to all instances. Back faces are culled unless double_faced is true.
