Approximates visbile points in an N dimensional point cloud, as seen from a given viewpoint.
This is the most basic implementation of:
"Direct Visibility of Point Sets",
Sagi Katz, Ayellet Tal, and Ronen Basri. SIGGRAPH 2007
Usage:
visiblePtInds=HPR(p,C,param)
Input:
p - NxD D dimensional point cloud.
C - 1xD D dimensional viewpoint.
param - parameter for the algorithm. Indirectly sets the radius.
Output:
visiblePtInds - indices of p that are visible from C. |
