Common Parametric (2D)
Texture Parameters
The following texture parameters are common to parametric (2D) textures:
| Parameter | Absolute Range | Useful Range | Default | Description: |
| 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 |
The parametric textures are: Bulge, CheckerCloth texture, File texture, Fractal, Grid, Mountain, Noise, Ramp, Stencil, and Water.
