FXTrigField

Description
A shader that produces a force field effect using trigonometric functions.

Usage
Color adjusts the field color. Rate adjusts the rate at which the field moves. Scale adjusts the granularity of detail seen in the field. This shader has two configuration defines:

#define USE_TAN
Default. When this symbol is defined, the field has more defined patterns and will over-saturate the colors, yielding more of an energy effect. When this symbol is not defined (i.e., #undef USE_TAN), the field is generally amorphous in appearance.

#define USE_LINES
Disabled by default. When this symbol is defined, any patterns appear linear rather than curved. By default this symbol is not defined (i.e., #undef USE_LINES).
