Sample Points (Volume)¶
Generate random points inside given mesh.
Tip
In Blender, parent an object to the resulting point cloud and set “Instancing” to “Verts” in the point cloud Object properties.
This way you can create similar effects to a particle system with Emit from volume. Points from the MfxVTK effect have a different look and they are static – you don’t have to worry about generating particles or baking them.
- Input
polygonal mesh (should be closed)
- Output
point cloud
- VTK classes
vtkImplicitPolyDataDistance
Options¶
- Number of points
How many points should be generated.
Note
If your mesh is very thin or tiny relative to its bounding box, the effect may fail to sample all points. In this case, increasing desired number of points may help (it will not give up as early).
- Distribute uniformly
If this option is turned on, the points will be distributed pretty evenly across the volume (quasi-random, low discrepancy sampling).
If this option is off, the points will be sampled more chaotically across the volume (pseudo-random uniform distribution over bounding box).
- Auto simplify
Allow the effect to simplify (decimate) the mesh for sampling, dramatically improving performance for large meshes. In rare cases, this may lead to points being sampled outside the original mesh. If this happens, you can try turning this off.
