how to tile a texture

I tried to tile the 'ground' by texturing using the code below. Rather than tile, however, the texture image is enlarged to texture the ground -- with no repeat. What code can I use to ensure that the texture image tiles rather than stretches?

ground = viz.add('tut_ground.wrl')
ground.setPosition(0,0,0)
ground.collidePlane()
leaves = viz.add('fall-leaves.jpg')
leaves.wrap(viz.WRAP_S,viz.REPEAT)
leaves.wrap(viz.WRAP_T,viz.REPEAT)
ground.texture(leaves)

You need to apply a texture matrix to the ground model to scale the texture coordinates up. Here is some sample code:

Code:

#Number of times to repeat texture horizontally/vertically

NUMBER_OF_REPEATS = 10



leaves = viz.add('fall-leaves.jpg',wrap=viz.REPEAT)



ground = viz.add('tut_ground.wrl')

ground.setPosition(0,0,0)

ground.collidePlane()

ground.texture(leaves)



#Apply a texture matrix that scales to number of repeats

ground.texmat( viz.Matrix.scale(NUMBER_OF_REPEATS,NUMBER_OF_REPEATS,1) )
