Graph VectorField Generator
The Graph vector-field generator uses a PopcornFX nodegraph to compute the vector of each voxel from its UVW or integer coordinates.

When generating an animated vector-field, time in seconds of the emd of the animation (on the last frame) |
Vector Graph
The vector graph is run once per voxel of the final vector-field, to compute the value of this voxel’s vector.
The base vector graph consists of an input template VectorFieldGeneratorArgs, which outputs various useful properties such as the UVW coordinates of the voxel, and an output template VectorFieldGeneratorOutputs, which expects as an input the vector to write into the voxel.
Current Limitations
-
You cannot make local templates
-
You cannot use custom attributes
-
The simulation will be one-shot, it cannot be iterated over multiple frames to make a simulation converge using previous voxel values
Available Inputs
The VectorFieldGeneratorArgs template outputs the following values:
