This example demonstrate a minimal visualization created with VTK.
[C++](/Cxx/Rendering/CylinderRenderingProperties] and Java.
#!/usr/bin/env python # This simple example shows how to do basic rendering and pipeline # creation. import vtk # The colors module defines various useful colors. from vtk.util.colors import tomato # This creates a polygonal cylinder model with eight circumferential # facets. cylinder = vtk.vtkCylinderSource() cylinder.SetResolution(8) # The mapper is responsible for pushing the geometry into the graphics # library.
