Subject: Re: [MayaVi-users] How to transform and rotate parametric surfaces?
To: Roan LaPlante <aestri...@gmail.com>
I just want a quick way to draw primitives (tori, spheres, cones,
cylinders) in a scene with particular dimensions and be able to rotate and
translate them with respect to other objects I've created with mlab.mesh.
Ideally I'd like something like:
torus = mlab.Torus()
torus.center = [2., 3., 4.]
torus.orientation = [[0.1, 0.1, 0],
[0.2, 0.3, 0],
[0, 0, 1]]
torus.ring_radius = 5.0
torus.cross_section_radius = 0.2
mlab.show()
Does the tvtk or mayavi api offer anything like this?
