Left Toolbar > 3D Nodes > * Mesh Normal Angle Node *
The Mesh Normal Angle node rendeers the angle between the surface normal, and a vector defined in the attributes. The 0 degress angle value is rendered as white, and the 180 degrees value is rendered as black.
Load one of more model in the Scene Window.
On the left toolbar choose 3D Nodes > Mesh Normal Angle. >
Drag the Mesh Normal Angle icon into the Node Graph.
A monochromatic image where the white values represent and angle of 0 degrees between the normal and the defined vector, and black is an angle of 180 degrees.
Position X Position X of the output image.
Position Y Position Y of the output image.
Size X Size X of the output image.
Size Y Size Y of the output image.
Vector X Coordinate x of the vector.
Vector Y Coordinate y of the vector.
Vector Z Coordinate z of the vector.
The following examples were rendered using a 200 x 200 Plane model, and two points at A (-50,-50,0) and B (50, 50, 0).
