Defined in: C4Computation.h

Returns a pointer to a table of precomputed cosine and sine values.

Prototype

const ConstVector2D *GetTrigTable(void);

Description

The GetTrigTable function returns a pointer to a table of 256 precomputed cosine and sine values. Entry k in the table corresponds to the angle (k/255)·360 degrees. Each entry in the table is a 2D vector whose x coordinate holds the cosine of the angle and whose y coordinate holds the sine of the angle.
