Grid

GridRGB generates a color grid pattern based on the surface u, v parameters. The default case is white lines on a black background (filler). The "contrast" variable controls the relative contrast of the line color to the filler color. A "contrast" of 0.0 will set the color to the average of the line color and the filler color. A "contrast" of -1.0 will swap the line color and the filler color.

Argument Name	Absolute Range	Useful Range	Default	Description
contrast	-1.0, 1.0	-1, 1	1.0	Relative contrast of the colors
uwidth	0, 0.5	0, 0.5	0.1	Width of lines in the u direction
vwidth	0, 0.5	0, 0.5	0.1	Width of lines in the v direction
line_color (triple)	0, infinity	0, 255	255.0	Line color
filler_color (triple)	0, infinity	0, 255	0.0	Area between lines color
urepeat	-infinity, infinity	-10.0, 10.0	1.0	# of copies in u direction within coverage area.
vrepeat	-infinity, infinity	-10.0, 10.0	1.0	# of copies in v direction within coverage area.
uoffset	-infinity, infinity	-1.0, 1.0	0.0	U offset repeat within coverage area
voffset	-infinity, infinity	-1.0, 1.0	0.0	V offset repeat within coverage area
ucoverage	-infinity, infinity	0.0, 1.0	1.0	amount of U surface to be textured
vcoverage	-infinity, infinity	0.0, 1.0	1.0	amount of V surface to be textured
utranslate	-infinity, infinity	-1.0, 1.0	0.0	amount of U coverage area to be moved.
vtranslate	-infinity, infinity	-1.0, 1.0	0.0	amount of V coverage area to be moved.
uwrap	TRUE FALSE		TRUE	flag to wrap texture around U boundaries of coverage area.
vwrap	TRUE FALSE		TRUE	flag to wrap texture around U boundaries of coverage area.
worldspace	TRUE FALSE		FALSE	flag to use world space texture mapping
rotate	-infinity, infinity	-360.0, 360.0	0.0	angle coverage area to be rotated
mirror	TRUE FALSE		FALSE	flag to match edges of texture
