Method psrdnoise
psrdnoise(float2, float2, Single)
2-D tiling simplex noise with rotating gradients and analytical derivative.
Declaration
public static float3 psrdnoise(float2 pos, float2 per, float rot)Parameters
| Type | Name | Description |
|---|---|---|
| float2 | pos | Input (x,y) coordinate. |
| float2 | per | The x and y period, where per.x is a positive integer and per.y is a positive even integer. |
| Single | rot | Angle to rotate the gradients. |
Returns
| Type | Description |
|---|---|
| float3 | The first component of the 3-element return vector is the noise value, and the second and third components are the x and y partial derivatives. |
