Indeed that speed up the visulaization.
One last question before leaving:
How can I update filter and pipeline objects after the reset. In my code
I have something like:
@on_trait_change('scene.activated')
def update_view(self):
self.pts = self.scene.mlab.quiver3d(x, y, z, self.scales, s, s,
...)
self.pts.mlab_source.dataset.lines = self.bonds
tube = self.scene.mlab.pipeline.tube(self.pts, tube_radius = 0.01)
surf = self.scene.mlab.pipeline.surface(tube, color=(0.8, 0.8, 0))
@on_trait_change('indexes')
def update_indexes(self):
self.pts.mlab_source.reset(x = x, y = y, z = z, u = self.scales,
v = s, w = s, ...)
but when changing the size of my datas (so when calling update_indexes),
I end up with warnings such as:
Warning: In C:\pisi\tmp\VTK-5.6.0-2\work\VTK\Graphics\vtkTubeFilter.cxx,
line 237
vtkTubeFilter (090CC9F8): Could not generate points!
Generic Warning: In
C:\pisi\tmp\VTK-5.6.0-2\work\VTK\Filtering\vtkPolyLine.cxx, line 104
Coincident points in polyline...can't compute normals
sorry for the dummy and numerous questions but I really do have hard
time getting into mayavi.
