PointsToLevelSet

Converts a points primitive to an OpenVDB level set.

user

Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.

enabled

The on/off state of the node. When it is off, the node outputs the input scene unchanged.

filter

The filter used to control which parts of the scene are processed. A Filter node should be connected here.

width

The name of a float primitive variable specifying the width of each point. The primitive variable may have either Vertex or Constant interpolation. If the primitive variable doesn’t exist, a width of 1.0 is used.

Note

A point’s width needs to be at least 3x voxelSize to contribute to the level set. Smaller points will be ignored, and reported as a warning.

widthScale

An additional multiplier on the width of each point.

useVelocity

Enables the creation of trails behind the points, based on the velocity primitive variable.

velocity

The name of a V3f primitive variable specifying the velocity of each point. Velocity is specified in local-space units per second, and the trail is automatically scaled to represent the motion within a single frame.

velocityScale

An additional multiplier applied to the velocity of each point.

grid

Name of the level set grid to be created.

voxelSize

Size of a voxel in the level set grid, specified in local space. Smaller voxel sizes will increase resolution, but take more memory and computation time.

halfBandwidth

Defines the exterior and interior width of the level set in voxel units.
