Component Mix Vector

Node Description & Purpose:
This node is used to blend or interpolate between the two input values. Unlike the normal Mix vector node, the Component mix vector node takes a vector as its Mix controller and allows you to individually mix the components of the input vectors. That means you can have different mix values for the X, Y and Z components:

Output.x = Input.x and Input 2.x mixed by Mix controller.x
Output.y = Input.y and Input 2.y mixed by Mix controller.y
Output.x = Input.z and Input 2.z mixed by Mix controller.z

The inputs are mixed using linear interpolation. If the mix value is 0 then the Input value will be output. If the mix value is 1 then the Input 2 value will be output. If the mix value is between 0 and 1 then the output will be a blended combination of the two input values.

Node Type: Function

Settings:

  • Input 2: This is where you specify the node for the Input 2 value.
  • Mix controller: This is where you specify the node that is used to control the mixing between the Input and Input 2 values. If you do not specify a mix controller a value of 0.5 is used to mix each component of the input vectors.


Error conditions

  • It is an error for there to be no Input value. In this the output vector will have all its components set to 0.
  • It is an error for there to be no Input 2 value. In this case the Input value is output.
  • If there is no Mix controller node attached then a value of 0.5 is used to mix each component of the input vectors.

A vector is a set of three scalars, normally representing X, Y and Z coordinates. It also commonly represents rotation, where the values are pitch, heading and bank.
