Method Detail

build

public void build(PrimitiveList primitives)

Description copied from interface: AccelerationStructure

Construct an acceleration structure for the specified primitive list.

Specified by:

build in interface AccelerationStructure

intersect

public void intersect(Ray r,
                      IntersectionState state)

Description copied from interface: AccelerationStructure

Intersect the specified ray with the geometry in local space. The ray will be provided in local space.

Specified by:

intersect in interface AccelerationStructure

Parameters:

r - ray in local space

state - state to store the intersection into

getGridIndex

private void getGridIndex(float x,
                          float y,
                          float z,
                          int[] i)
