VisualShaderNodeDerivativeFuncConstructor

C#
public VisualShaderNodeDerivativeFunc();

FunctionProperty

C#
public VisualShaderNodeDerivativeFunc.FunctionEnum Function { get; set; }

A derivative function type.

OpTypeProperty

C#
public VisualShaderNodeDerivativeFunc.OpTypeEnum OpType { get; set; }

A type of operands and returned value.

PrecisionProperty

C#
public VisualShaderNodeDerivativeFunc.PrecisionEnum Precision { get; set; }

Sets the level of precision to use for the derivative function. When using the Compatibility renderer, this setting has no effect.

Parameters
Name	Type	Default
`type`	`VisualShaderNodeDerivativeFunc.OpTypeEnum`	—

SetPrecisionvoid

C#
public void SetPrecision(VisualShaderNodeDerivativeFunc.PrecisionEnum precision);

Parameters
Name	Type	Default
`precision`	`VisualShaderNodeDerivativeFunc.PrecisionEnum`	—

Value	Description
`Max = 3`	Represents the size of the `VisualShaderNodeDerivativeFunc.FunctionEnum` enum.
`Sum = 0`	Sum of absolute derivative in `x` and `y`.
`X = 1`	Derivative in `x` using local differencing.
`Y = 2`	Derivative in `y` using local differencing.

Value	Description
`Max = 4`	Represents the size of the `VisualShaderNodeDerivativeFunc.OpTypeEnum` enum.
`Scalar = 0`	A floating-point scalar.
`Vector2D = 1`	A 2D vector type.
`Vector3D = 2`	A 3D vector type.
`Vector4D = 3`	A 4D vector type.

Value	Description
`Coarse = 1`	The derivative will be calculated using the current fragment's neighbors (which may not include the current fragment). This tends to be faster than using `VisualShaderNodeDerivativeFunc.PrecisionEnum.Fine`, but may not be suitable when more precision is needed. This is equivalent to using `dFdxCoarse()` or `dFdyCoarse()` in text shaders.
`Fine = 2`	The derivative will be calculated using the current fragment and its immediate neighbors. This tends to be slower than using `VisualShaderNodeDerivativeFunc.PrecisionEnum.Coarse`, but may be necessary when more precision is needed. This is equivalent to using `dFdxFine()` or `dFdyFine()` in text shaders.
`Max = 3`	Represents the size of the `VisualShaderNodeDerivativeFunc.PrecisionEnum` enum.
`None = 0`	No precision is specified, the GPU driver is allowed to use whatever level of precision it chooses. This is the default option and is equivalent to using `dFdx()` or `dFdy()` in text shaders.
