Parameters:

clContext - OpenCl Context

config - Configuration of BeamIntersectionVisitor

Method Details

release

public void release()

Description copied from interface: CLResources

Explicitly releases GPU resources held by this object

Specified by:

release in interface CLResources

computeClosestPoints

public Set<MeshPoint> computeClosestPoints(OctreeOpenCL octree,
 WriteBufferGPU<javax.vecmath.Point3d> originPoints,
 WriteBufferGPU<javax.vecmath.Vector3d> direction)

Computes closest ray intersections between rays and triangles loaded in octree, but reads results only as MeshPoint to save time

Parameters:

originPoints - Buffer of origin points

Returns:

Set of closest ray intersection mesh points

computeClosest

public Set<RayIntersection> computeClosest(OctreeOpenCL octree,
 WriteBufferGPU<javax.vecmath.Point3d> originPoints,
 WriteBufferGPU<javax.vecmath.Vector3d> direction)

Computes closest ray intersections between rays and triangles loaded in octree

Parameters:

originPoints - List of ray origin points

direction - Ray direction vector

Returns:

Set of closest ray intersection
