Member Function Documentation

void CE_BVH::build	(	const CE_Int32Array &	trisingrp,
		const cl::Buffer &	primptsidx,
		const cl::Buffer &	primpts,
		const cl::Buffer &	P,
		PrimType	primtype = PrimType::TRI,
		bool	refitTets = true
	)

void CE_BVH::buildEmpty

(

)

Build a valid but empty point BVH. All traversal queries return zero results immediately (the root node's child AABBs are at infinity so the distance check in BVH_TRAVERSE_BEGIN exceeds any finite threshold). All four kernel buffers (nodes, verts, idx, pts) are non-null so they can be bound to kernel arguments without error.

void CE_BVH::buildPoints	(	const CE_Int32Array &	pts,
		const cl::Buffer &	P
	)

Convenience overload for point BVH — no prim connectivity needed.
