rotateUV operation

Syntax

rotateUV(uvSet, angle)

Parameters

• uvSet (float)
  Number of texture coordinates set (integer number in [0,9]). The numbering corresponds to the texture layers of the material attribute, see also Texturing: Essential Knowledge.
• angle (float)
  Defines the angle of the rotation.

Description

This operation rotates the texture coordinates (uvs) of the current shape by the rotation angle.

Note.1: The rotation center is at the texture position u=0 and v=0.

Note.2: Rotating uvs works only after the uvs have been projected.

Examples

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

Example with standard uvs and rotated uvs:
