ComparisonVertexMask

Creates a vertex mask from the differences between geometries. Helps to preview small artifacts and barely noticeable bumps. Also generates dynamic masks for 4D sequence.

Inputs

Target geometry: Geometry A geometry to compare with.
Source geometry: Geometry A compared geometry. It’s topology defines the result vertex mask.

Output

VertexMask Vertex mask suitable for Source geometry with non-zero differences zones.

Parameters

Mode:

Delta Length: Fast mode for comparing geometries with same topology and vertex order. Vertex weight is computed from distance between 2 correpondent geom vertices.
Distance to Surface: Slower mode for different topology geometries. Projects vertices from the Target to the closest surface points on the Source geometry.
Distance by Target Normal: Projecting points from Target geometry, using it’s normals as ray directions.
Distance by Source Normal: Projecting points from Target geometry, using approximated Source normals as ray directions.

Mask Color:

preview vertex mask color in the Visual Editor.

Clamp Value:

if set, all distances will be clamped by Min and Max distances.

Normalize Distance:

if set, all distances are normalized in the range limited by Min and Max distances. Otherwise, the distance itself is used as weight, e.g. 0.7 cm will result in vertex mask weight 0.7. Normalizing is performed after Clamping if any.

Min Distance (cm):

defines clamp and normalize lower threshold.

Max Distance (cm):

defines clamp and normalize upper threshold.

Normal Direction:

defines normals direction in Distance by Target/Source Normal mode:

Forward: point normals outside the model.
Backward: point normals inside the model.
Both: use both, doubling the ray shots.
