class yt.utilities.lib.octree_raytracing.OctreeRayTracing(data_source)

Bases: object

cast_rays(vp_pos, vp_dir)

Cast the rays through the oct.

Parameters:

• vp_pos (float arrays (Nrays, Ndim))

• vp_dir (float arrays (Nrays, Ndim)) – The position (unitary) and direction of each ray

Returns:

• cell_index (list of integer arrays of shape (Ncell)) – For each ray, contains an ordered array of cell ids that it intersects with

• tvalues (list of float arrays of shape (Ncell, 2)) – The t value at entry and exit for each cell.
