Vertex Tab
Using the fields in the Vertex tab, vertex calculations can be performed on the Position,
Normals, Vertex Color, Texture Coordinates, Environment Coordinates, UV Tangents, and
Velocity attributes.
The vertices are defined by three XYZ Position values in world space as px, py, pz. Normals,
which define as a vector the direction the vertex is pointing as nx, ny, nz.
Vertex color is the Red, Green, Blue, and Alpha color of the point as vcr, vcg, vcb, vca.
Numbers Tab
Custom Vertex 3D node Numbers tab
Numbers 1-8
Numbers are variables with a dial control that can be animated or connected to modifiers
exactly as any other control might. The numbers can be used in equations on vertices at current
time: n1, n2, n3, n4,… or at any time: n1_at(float t), n2_at(float t), n3_at(float t), n4_at(float t),
where t is the time you want. The values of these controls are available to expressions in the
Setup and Intermediate tabs. They can be renamed and hidden from the viewer using the
Config tab.
