Points 1-8
The point controls represent points in the Custom Vertex 3D tool, not the vertices. These eight
point controls include 3D X,Y,Z position controls for positioning points at the current time:
(p1x, p1y, p1z, p2x, p2y, p2z) or at any time: p1x_at(float t), p1y_at(float t), p1z_at(float t), p2x_
at(float t), p2y_at(float t), p2z_at(float t), where t is the time you want. For example, you can use
a point to define a position in 3D space to rotate the vertices around. They can be renamed and
hidden from the viewer using the Config tab. They are normal positional controls and can be
animated or connected to modifiers as any other node might.

LUTs 1- 4
The Custom Vertex 3D node provides four LUT splines. A LUT is a lookup table that will
return a value from the height of the LUT spline. For example, getlut1(float x), getlut2(float x),...
where x = 0 … 1 accesses the LUT values.
The values of these controls are available to expressions in the Setup and Intermediate tabs
using the getlut# function. For example, setting the R, G, B, and A expressions to getlut1(r1),
getlut2(g1), getlut3(b1), and getlut4(a1) respectively, would cause the Custom Vertex 3D node to
mimic the Color Curves node.
These controls can be renamed using the options in the Config tab to make their meanings
more apparent, but expressions still see the values as lut1, lut2,...lut8.
