2D Perlin Noise and 2D Animated Perlin Clouds Classes

[Killingsworth]

Hello, this is my first gift to the community here at irrlicht. It is a perlin noise generator. It can generate a 2D array of perlin noise, or it can render it out to a texture. My example shows how to class can be expanded to create intresting things, such as procedural clouds. The FPS represented is probably as false as can be, I'm on an anceint computer. So if anyone compiles this it would be much appreciated to return the FPS you get. If anyone finds bug/ways to optimize/errrors please let me know. I will appreciate it much.

Now without further adeu:

Included in the zip:
CPerlinNoise.h: Noise class also containing cloud class
main.cpp: example showing how to use the class
functions.h: some simple functions, not really important, but one is needed for the example.

LOL. I think you are correct about your fps.
I compiled your main and got the following:

I changed the octaves setting.

2= 47fps
4= 28
6= 20
8= 15

Not a bad little app you made there.

Thanks much. Perlin noise does take quite a bit of power to make. A better way to do it is to make certain number of maps at runtime and cycle through them without generating a new one every 50 steps.

Libnoise had done a pretty cool job and can be integrated easily with Irrlicht.

Also take a look at FxGen:
