Simple Apply Texture rule

ScottAulen2 — Tue, 03 Feb 2015 21:00:42 GMT

I'm looking for a simple rule to add textures to flat polygons, similar to the Apply Color rule found in the Essential Skills Training tutorials. Any help?

Texture -->

setupProjection(0, scope.xy, 1, 1) #not necessary for sides

texture("images/bricks.jpg")

projectUV(0)

If it is the start shape, then use scope.xz rather than scope.xy.

Thanks, Z R. That worked perfectly. Now what if I want to extrude the polygon slightly (say between 0-5 feet) but still have the textures? It's fine if the texture is the same for the top and sides (in fact that would be preferred).

Here's how I do it.

Lot -->
  extrude(5)
  #comp(f){all: Texture} #this would texture everything;
  #the stuff below addresses every side on its own. side: also works, to address all sides.
  comp(f){
  left: rc |
  right: rc |
  top: Texture |
  bottom: rc |
  front: rc |
  back: rc
  }


Texture -->
  setupProjection(0, scope.xy, 1, 1)
  texture("images/bricks.jpg")
  projectUV(0)

rc --> color(rand,rand,rand)

This is correct as well. Thanks again, Z R.
