IDCompositionTurbulenceEffect interface (dcomp.h)
The turbulence effect is used to generate a bitmap based on the Perlin noise function. The turbulence effect has no input image.
Inheritance
The IDCompositionTurbulenceEffect interface inherits from IDCompositionFilterEffect. IDCompositionTurbulenceEffect also has these types of members:
Methods
The IDCompositionTurbulenceEffect interface has these methods.
| IDCompositionTurbulenceEffect::SetBaseFrequency Sets the base frequencies in the X and Y direction. |
| IDCompositionTurbulenceEffect::SetNoise Sets the turbulence noise mode. |
| IDCompositionTurbulenceEffect::SetNumOctaves Sets the number of octaves for the noise function. |
| IDCompositionTurbulenceEffect::SetOffset Sets the coordinates where the turbulence output is generated. |
| IDCompositionTurbulenceEffect::SetSeed Sets the seed for the pseudo random generator. |
| IDCompositionTurbulenceEffect::SetSize Sets the size of the turbulence output. |
