Redshift supports a wide variety of commonly used math operation shaders for both scalar (float) values and vectors. All math nodes that process float values are listed here:
|
|
Returns the absolute value of Input. For example, a value of -1.0 will be returned as 1.0.
|
Returns Input 1 + Input 2.
|
Returns the arc-cosine of Input. When Radians is selected, the output range will be between 0 and PI, otherwise 0 and 180 degrees.
|
Returns the arc-sine of Input. When Radians is selected, the output range will be between -PI/2 and PI/2, otherwise -90 and 90 degrees.
|
Returns the arc-tangent of Input 1 and Input 2. When Radians is selected, the output range will be between -PI/2 and PI/2, otherwise -90 and 90 degrees.
|
Returns the arc-tangent of Input. When Radians is selected, the output range will be between -PI/2 and PI/2, otherwise -90 and 90 degrees.
|
Returns a curved bias of Input by Bias, using the following Ken Perlin formula: pow(Input, log(Bias)/log(0.5))
|
Returns Input remapped from Old Range values to New Range values, with an optional clamp.
|
Returns the cosine of Input. When Radians is selected, the input will be assumed to be in radians, otherwise degrees.
|
Returns Input 1 / Input 2.
|
Returns the exponential of Input, using the following formula: e^ Input
This is the inverse function of Ln.
|
Returns the integer part of Input. For example, 1.5 will be returned as 1.0.
|
Returns the fractional part of Input. For example, 1.5 will be returned as 0.5.
|
Returns a contrast gain of Input by Gain, using the following Ken Perlin formula:
Bias( 2 * Input, 1 - Gain ) * 0.5 ; if Input < 0.5
1 - Bias( 2 - 2 * Input, 1 - Gain ) * 0.5 ; otherwise
|
Returns the 1 - Input.
|
Returns the natural logarithm (to base e) of Input.
This is the inverse function of Exp.
|
Returns the logarithm of Input to Base.
This is the inverse function of Pow.
|
Returns the maximum of Input 1 and Input 2.
|
Returns the minimum of Input 1 and Input 2.
|
Returns Input 1 linearly interpolated to Input 2 by Mix. When Mix is 0.0, Input 1 will be returned. When Mix is 1.0, Input 2 will be returned.
|
Returns the modulo of Input by Divisor. For example 7 modulo 5 will be returned as 2.
This is the remainder of Input / Divisor.
|
Returns Input 1 * Input 2.
|
Returns 0 - Input.
|
Returns Base^ Exponent.
This is the inverse function of Log.
|
Returns 1 / Input.
|
Returns Input clamped to values between 0 and 1, inclusively. For example -1.5 will be returned as 0.0 and 1.5 will be returned as 1.0.
|
Returns -1 if Input is a negavitve number and 1 otherwise.
|
Returns the sine of Input. When Radians is selected, the input will be assumed to be in radians, otherwise degrees.
|
Returns the square-root of Input.
|
Returns Input 1 - Input 2.
|
Returns the tangent of Input. When Radians is selected, the input will be assumed to be in radians, otherwise degrees.
