Multiply Divide

Multiplies or divides input attributes. This utility is divided into three parts—two input attributes, an operator you apply to the two input attributes, and an output attribute to hold the result of the operation. The input and output attributes represent X, Y and Z. Use this node to multiply colors or triple-value attributes.

Find this utility in the Create Bar (see Hide, resize or customize the Create bar).

To use this utility, see Use the Multiply Divide utility.

Operation

Displays a pop-up menu from which you can select an operator.

No operation

Copies the value of the Input1 attribute to the output attribute without making any changes.

For example, if Input 1 is a Checker texture and Input 2 is a Crater texture, when you select No Operation, only the Checker texture’s attributes are rendered.

Multiply

Multiplies the Input1 attribute and the Input2 attribute, as in the following formula:

Output = Input1 x Input2

Divide

Divides the Input1 attribute by the Input2 attribute, as in the following formula:

Output = Input1 / Input2

In the following example, the Input 1 texture is divided by the changes made to the Input 2 texture.

Power

Sets the output to equal Input 1 raised to the power of Input 2. See the following example:

It evaluates an expression by raising the value to the power of a number you choose or by calculating the square root. Raising a value to the power means multiplying a number by itself a given number of times as in:

2^3 = 2 x 2 x 2

The command for calculating the square of a number is:

power (value, 2.0)

The mathematical formula is:

Power = value^2

The formula for computing the square root is:

Power = sqrt(value)

If you want to multiply the value of a component twice, you would set Input1 to represent the color (possibly mapping it with a texture), and then set all the three components of Input2 to 2.0. Because the inputs are both colors, you can work on the color of a single-component value or on all three-component values.

You can also get the square root of a number by setting Input2 to 0.5 as shown in the following:

Output = power (input1, input2)

which, in math terms, would be written like input1^input2.

See also the Power operator example.

Input1
