Members

cpBBArea cpFloat cpBBArea(cpBB bb): Returns the area of the bounding box.
cpBBCenter cpVect cpBBCenter(cpBB bb): Returns the center of a bounding box.
cpBBClampVect cpVect cpBBClampVect(cpBB bb, cpVect v): Clamp a vector to a bounding box.
cpBBContainsBB cpBool cpBBContainsBB(cpBB bb, cpBB other): Returns true if @c other lies completely within @c bb.
cpBBContainsVect cpBool cpBBContainsVect(cpBB bb, cpVect v): Returns true if @c bb contains @c v.
cpBBExpand cpBB cpBBExpand(cpBB bb, cpVect v): Returns a bounding box that holds both @c bb and @c v.
cpBBIntersects cpBool cpBBIntersects(cpBB a, cpBB b): Returns true if @c a and @c b intersect.
cpBBIntersectsSegment cpBool cpBBIntersectsSegment(cpBB bb, cpVect a, cpVect b): Return true if the bounding box intersects the line segment with ends @c a and @c b.
cpBBMerge cpBB cpBBMerge(cpBB a, cpBB b): Returns a bounding box that holds both bounding boxes.
cpBBMergedArea cpFloat cpBBMergedArea(cpBB a, cpBB b): Merges @c a and @c b and returns the area of the merged bounding box.
cpBBNewForCircle cpBB cpBBNewForCircle(cpVect p, cpFloat r): Constructs a cpBB for a circle with the given position and radius.
cpBBSegmentQuery cpFloat cpBBSegmentQuery(cpBB bb, cpVect a, cpVect b): Returns the fraction along the segment query the cpBB is hit. Returns INFINITY if it doesn't hit.
cpBBWrapVect cpVect cpBBWrapVect(cpBB bb, cpVect v): Wrap a vector to a bounding box.
