cf_noise_pixels_wrapped¶
Category: noise
GitHub: cute_noise.h
Creates an image from noise that can animate in a loop, and tiles seamlessly.
CF_Pixel* cf_noise_pixels_wrapped(int w, int h, uint64_t seed, float scale, float time, float time_amplitude);
| Parameters | Description |
|---|---|
| w | The width of the image. |
| h | The height of the image. |
| seed | Used to seed the sequence of numbers generated. Default 0. |
| scale | Scales up or down the noise in the image, like zooming in or out. Default 1.0f. |
| time | A time parameter for animation. |
| time_amplitude | Adjusts how much the animation evolves over the period. Default 1.0f. |
Return Value¶
Returns a generated image filled with noise.
Remarks¶
The generated image can be animated over a loop, and tiles seamlessly in the x-y directions. To control the animation pass in a float starting at 0, and incremented with CF_DELTA_TIME each game tick. This will loop the animation over a one-second period. You can divide your accumulated time by a frequency to set a number of seconds to loop over.
If you want the animation to move faster without adjusting the loop time, then adjust time_amplitude. This scales how
much the animation will evolve over time. Higher values will have faster and more volatile looking motions.
