示例1: initializeQuadrant
void initializeQuadrant(QuadTree* quadtree, const Box2D& quadrantBounds, unsigned int depth, unsigned int index, unsigned int offset, unsigned int levelWidth)
{
unsigned int i = offset + index;
// FIXME: checking boundaries
if (i >= quadtree->maxQuadrants)
{
throw std::exception("max. quadrants overflow");
}
Quadrant& quadrant = quadtree->quadrants[i];
quadrant.depth = depth;
quadrant.bounds = quadrantBounds;
if (depth == quadtree->maxDepth - 1) // leaf
{
quadrant.edges = quadtree->numQuadrantEdges++;
return;
}
unsigned int baseIndex = (index * 4);
unsigned int newOffset = offset + levelWidth;
unsigned int newLevelWidth = levelWidth * 4;
unsigned int newDepth = depth + 1;
vml_vec2 subQuadrantSize = quadrantBounds.getExtents() / 2.0f;
for (unsigned int y = 0, i = 0; y < 2; y++)
