Hello,<br>
<br>
I have a mesh = rectilinear grid, and objects meshed in this grid. To each "cell" of the grid either an object is assigned, or the cell is left empty. Now I want to visualize the non-empty cells with differently colored cubes (cells) with a color corresponding to specific objects.<br>
<br>
The primitive way I used for the visualization is to create a vtkCubeSource->vtkPolyDataMapper->vtkActor pipeline for each non-empty cell and see in this way the meshed objects. However, the number of cells in a typical mesh is about 1.000.000 with ca. 100.000 non-empty cells, which results in very large processing time of VTK making any interactive usage impossible.<br>
<br>
Does anybody have an idea how to do the visualization in a better way? Can I maybe somehow use glyphing?<br>
<br>
Many thanks!<br>
Petr<br>
