Attribute Math¶

Modify an attribute with a math operation.

The Attribute Math Node.¶

Inputs¶

Geometry: Standard geometry input.
A, B, C: The first and second input to the math operation. This is either an attribute name or numeric value.
Result: Name of the attribute where the computed result is stored. A new attribute with that name is added if it does not exist yet. If it does exist, the values of the existing attribute are overridden.

Operation

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

Sine: The Sine of the input value.
Cosine: The Cosine of the input value.
Tangent: The Tangent of the input value.
Arcsine: The Arcsine of the input value.
Arccosine: The Arccosine of the input value.
Arctangent: The Arctangent of the input value.
Arctan2: Outputs the Inverse Tangent of the first value divided by the second value measured in radians.
Hyperbolic Sine: The Hyperbolic Sine of the input value.
Hyperbolic Cosine: The Hyperbolic Cosine of the input value.
Hyperbolic Tangent: The Hyperbolic Tangent of the input value.

Conversion

Note

Attributes are converted implicitly to the float data type.
