[vtkusers] A set of spheres within one actor?

[Allan James]

Hi Piotr,

You can also try using vtkSphereSource along with a vtkGlyph3D to produce a single actor with many spheres. This allows you to place a sphere glyph at each point in the input dataset. This will result in much higher performance than using a single actor for each individual sphere.

Cheers,

Hi Piotr,

If I have understood you correctly all you need is to use the
class vtkAssembly. Please mind that there are some performance
concerns related to the rendering of collections of assemblies (see
class doc) but that may be not an issue in your case.

In the attachment there is an ad-hoc script illustrating the
use of vtkAssembly.

I hope that this will be helpful.

Regards,

Roman
