NSLT

Initiates a Non-sequential LightningTrace.

Syntax:

NSLT surf, source, ray_sampling, edge_sampling
 

Discussion:

Surf is an integer value that indicates the number of the Non-sequential surface. If the program mode is set to Non-Sequential, use 1. Source refers to the object number of the desired source. If source is zero, all sources will be traced. Ray_sampling refers to the resolution of the LightningTrace mesh, with valid values being between 0 (corresponding to a mesh resolution of "Low (1X)") and 5 (corresponding to a mesh resolution of "1024X").

Edge_sampling refers to the resolution used in refining the LightningTrace mesh near the edges of objects, with valid values being between 0 (corresponding to a mesh resolution of "Low (1X)") and 4 (corresponding to a mesh resolution of "256X"). For more details on LightningTrace, see "The LightningTrace Control".

NSLT always calls UPDATE before executing a LightningTrace to make certain all objects are correctly loaded and updated.

Example:

NSLT 1, 0, 3, 2
