This extension aims to make noise calculations on the GPU.

Calculating noise on the GPU is faster than doing it on CPU couple of thousand times. This is the best method if the noise is going to be used as an image (for image processing or compositing images).

If the calculated noise needs to be turned into an array of numerical data, the process gets slower. The bottleneck is not calculating the noise, but getting the data from the image.

Since calculating noise on the GPU is extremely fast, this extension lets you calculate big sample data at once, and cache it. This is a design choice to make the process more efficient.

This initial calculation is done by the "create" script.

Some benchmark results are presented below for the
create script to give you an idea:

*   256x256 gpu perlin noise calc. -> ~  1.7 ms (milliseconds)
* 1024x1024 gpu perlin noise calc. -> ~ 13.5 ms
* 2048x2048 gpu perlin noise calc. -> ~ 43.0 ms

(Numbers may change for you depending on your CPU and GPU)

The extension caches the calculated noise in a buffer so the data lookup is as fast as looking up data from an array.

This look up actions can be done using the "gpu_noise" scripts. gpu_noise_*d scripts are fast and can be run several times on a single step event without reducing the performance of the application/game.

Here are some benchmark results for looking up
calculated noise data:

Cached data lookup    -> ~ 0.005 ms per lookup
Un-cached data lookup -> ~ 1.5 ms per lookup 

(Numbers may change for you depending on your CPU)

Spliting the process into "create" and "lookup" gives developers a flexibility. Several noise maps can be created (for such as landmass, atmosphere, vegitation etc.) on a loading screen and look data up realtime with inexpensive scripts.


// create a noise using GPU
landmass = gpu_noise_create(noisetype, seed, width, height);

// or 
// use create_ext script if you need more options
landmass = gpu_noise_create_ext(noisetype, seed, width, height, persistence, frequency, scale);

var value = gpu_noise_3d(landmass, x, y, z);

// That's it. REMEMBER to delete the data from the memory using:


// if you need to create different chunks of noise, use offset script
landmass = gpu_noise_offset(width, [height, z]);

// if you get the GPU calculated noise as a surface,
var surface = gpu_noise_to_surface(landmass);

// REMEMBER to delete the data from the memory using:
// This will delete the surface and the buffer.
