rotateUV operation

Syntax

• rotateUV (uvSet, rotAngle)

Parameters

1. uvSet—integer (range[0,5])
   Number of texture coordinates set. The numbering corresponds to the texture layers of the material attribute, see also texturing: essential knowledge.
2. rotAngle—float
   Defines the angle of the rotation.

Description

The rotateUV operation rotates the texture coordinates (uvs) of the current shape by the rotAngle.

Note:

The rotation center is at the texture position u=0 and v=0. Rotating uvs works only after the uvs have been projected.

Examples

Here is an example of standard uvs and rotated uvs. brickMap = "assets/bricks.jpg" dirtMap = "assets/dirt.jpg" randBuildingHeight = 1 Lot --> s ('.75,'1,'.75) center(xz) extrude(world.up, randBuildingHeight) comp(f) { side : Facade | top : set(material.color.a, .3) Roof. } Facade --> # color, uv set 0 setupProjection(0, scope.xy, scope.sx, scope.sy) texture(brickMap) projectUV(0) # projection of the uvs rotateUV(0,10) # rotate command after the projection
