Example #1

File: kdbuild.cpp Project: lukaszdk/lzrt

// MakeLeaf
void KDBuildJob::MakeLeaf(kdbuffer_t *kdb)
{
	int n = kdb->node;
	
	leaves[curleaf] = n;

	nodes[n].left = KD_LEAF;
	nodes[n].leafid = curleaf;	

	curleaf++;

	nodes[n].numpolys = kdb->size;
	numleafpolys += kdb->size;

	if(kdb->size > 0)
	{
		nodes[n].polys = (kdpoly_t*)BufferAllocate(polybuffer, nodes[n].numpolys);

	
		for(int i=0; i < kdb->size; i++)

			aabb_t *a = &kdb->aabb[i];

			memcpy(&nodes[n].polys[i].triangle, a->poly->triangle, sizeof(triangle_t));
			memcpy(&nodes[n].polys[i].normal, a->poly->normal, sizeof(normal_t));
			memcpy(&nodes[n].polys[i].color, a->poly->color, sizeof(float[4]));
