Changeset 445 for trunk/VUT/GtpVisibilityPreprocessor/scripts/default.env

Timestamp:

12/02/05 20:38:01 (19 years ago)

Message:

Added VspBspTree? functionality:
This is a view space partitioning specialised BSPtree.
There are no polygon splits, but we split the sample rays.
The candidates for the next split plane are evaluated only
by checking the sampled visibility information.
The polygons are employed merely as candidates for the next split planes.
