texturing on-the-fly objects

I would like to apply a simple texture to an on-the-fly QUAD:

Code:

viz.startlayer(viz.QUADS)

viz.vertex(-.5,0,0)

viz.vertex(.5,0,0)

viz.vertex(.5,-DELTA,11)

viz.vertex(-.5,-DELTA,11)

plank = viz.endlayer()



plank.texture("wood.gif")

doesn't do it ... am I doing something wrong?

Hi,

Two problems. First, for each vertex you need to define a texture coordinate. Second, you need to add the texture before you apply it to an object. Sample code:

Code:

viz.startlayer(viz.QUADS)



#Lower left vertex

viz.texcoord(0,0)

viz.vertex(...)



#Upper left vertex

viz.texcoord(0,1)

viz.vertex(...)



#Upper right vertex

viz.texcoord(1,1)

viz.vertex(...)



#Lower right vertex

viz.texcoord(1,0)

viz.vertex(...)



plank = viz.endlayer()



plank.texture(viz.add('wood.gif'))
