3d model rotation?

is there any way to rotate a 3d model? instead 'absolute' rotate, I need 'relative' rotate a 3d model imported from wrl fie.
Thanks in advance

Hi Howard,

The following example will rotate a model 45 degrees along the absolute y axis:

Code:

model.rotate(0,1,0,45,viz.RELATIVE)

The following example will rotate a model 45 degrees along its local y axis:

Code:

viz.rotate(model,viz.YAXIS,45)

If you need more advanced control you could use the Transform class. Here's a simple example:

Code:

import vizmat

X = vizmat.Transform()



X.makeRot(0,1,0,90)

X.postRot(0,1,45)



model.update(X)

Hope this helps!
