Houdini 13.0 Nodes

interface version 1

Visualize volume voxel values by converting each voxel to a point.

...

Note

In order to allow the most exact inspection of volumes, this operator performs an 1:1 voxel-to-point conversion, as much as possible – exactly one point will be created for each voxel, containing exact (non-interpolated) value(s) for that specific voxel.

In situations where this is not possible (e.g. volumes with different resolutions), the first volume (scalar) will always be extracted with this accurate method.

Parameters

...

To Do

  • NOTE: if scalar and vector fields don’t match up – trouble :(

  • vex: how to get vector field value by a single op?!?!?!?!

  • prune should consider all field values (not just scalar)

  • better scalar/vector field menu builders

  • visualize vector fields (x/y/z volumes)

  • vector lengths as scalars (and scalar colors)

  • (DONE) postprocess jitter (voxel size-aware)

  • fast/approximate mode (two times the work :( but important)

  • ...
