输入选项

The inputs of the node are dynamic. Some inputs are only available in certain operations. For instance, the Addend input is only available in the Multiply Add operator.

值(明度)

Input Value. Trigonometric functions read this value as radians.

Addend

Input Addend.

Base

Input Base.

Exponent

Input Exponent.

Epsilon

Input Epsilon.

Distance

Input Distance.

Min

Input Minimum.

Max

Input Maximum.

Increment

Input Increment.

Scale

Input Scale.

Degrees

Input Degrees.

Radians

Input Radians.

属性

操作

The mathematical operator to be applied to the input values:

  • Functions

    • Add

      The sum of the two values.

      Subtract

      The difference between the two values.

      Multiply

      The product of the two values.

      Divide

      The division of the first value by the second value.

      Multiply Add

      The sum of the product of the two values with Addend.

      Power

      The Base raised to the power of Exponent.

      Logarithm

      The log of the value with a Base as its base.

      Square Root

      The square root of the value.

      Inverse Square Root

      One divided by the square root of the value.

      Absolute

      The input value is read with without regard to its sign. This turns negative values into positive values.

      Exponent

      Raises Euler’s number) to the power of the value.

    Comparison

    • Minimum

      Outputs the smallest of the input values.

      Maximum

      Outputs the largest of two input values.

      Less Than

      Outputs 1.0 if the first value is smaller than the second value. Otherwise the output is 0.0.

      Greater Than

      Outputs 1.0 if the first value is larger than the second value. Otherwise the output is 0.0.

      Sign

      Extracts the sign of the input value. All positive numbers will output 1.0. All negative numbers will output -1.0. And 0.0 will output 0.0.

      Compare

      Outputs 1.0 if the difference between the two input values is less than or equal to Epsilon.

      Smooth Minimum

      Smooth Minimum.

      Smooth Maximum

      Smooth Maximum.

    Rounding

    • Round

      Round the input value to the nearest integer.

      Floor

      Rounds the input value down to the nearest integer.

      Ceil

      Rounds the input value up to the nearest integer.

      Truncate

      Outputs the integer part of the value.

      Fraction

      Fraction.

      Modulo

      Outputs the remainder once the first value is divided by the second value.

      Wrap

      Outputs a value between Min and Max based on the absolute difference between the input value and the nearest integer multiple of Max less than the value.

      Snap

      Round the input value to down to the nearest integer multiple of Increment.

      Ping-pong

      The output value is moved between 0.0 and the Scale based on the input value.

    Trigonometric

    Conversion

    • To Radians

      Converts the input from degrees to radians.

      To Degrees

      Converts the input from radians to degrees.

钳制

Limits the output to the range (0.0 to 1.0). See Clamp.
