Invert
Outputs the inverse of the input. For example, an input of 5 produces an output of 0.2 (1/5). Choose
the node’s data type in the Attribute manager.
You can use this node to invert numbers or matrices. For example, you can
combine this node with a MatrixMulVector node to convert a position from
world coordinates to local coordinates. In the Attribute manager, choose
whether a real number or a matrix should be inverted.
Math
The Math node performs a math operation such as addition or multiplication. Choose the function
and data type in the Attribute manager.
Add
Adds the inputs together and outputs the result. This is the default function.
Subtract
Subtracts the second (and any additional) input from the rst and outputs the result.
Multiply
Multiplies the inputs and outputs the result.
Divide
Divides the rst input by the second input by each of the remaining inputs and outputs the result.
E.g. 10 / 2 / 4 = 20 = (10 * 4) / 2.
