Can you use the routines to generate sound intead of images? TIA ----- Original Message ----- From: <dm31 at uow.edu.au> Subject: Re: Perlin Noise - Texture Generator |Can they be made to tile? Well, I've done a bit of work on getting the textures to tile, so here are the first results. Of course you could always just do a cut and paste job, mirroring the image... I find not the best to look at however, since you see the symmetry in each tile. I still got some changes to try out with the tiling algo, but it seems to give reasonable results, without the image appearing symmetrical. Attached is a 128x126 sample, using 6 layers and cosine interpolation.

Could you give me any details on what information it should be able to produce?? Attached is a pix of a early attempt. I just displayed the wave form on the screen. Is there a Eu lib that I could easily use to produce wav files out of raw data? Only got intranet/mailbox access still, so I can't search the archives :( --'ThIs-RaNdOm-StRiNg-/=_.681210609:

This is a multi-part message in MIME format. ------=_NextPart_000_0035_01C29182.D10A89E0 charset="iso-8859-1" The wave shape shown in your .bmp does not seem to correspond to noise, but rather to a definite pitch sound. However, it is difficult to tell that from such a short sample. But I am interested in the routine you used to generate it. If at all possible, please post it to the forum or send me it by mail. Attached you will find two text files describing the .wav format. I downloaded them, I think, from www.wotsit.com, or somewhere similar. You will also find a .ex file. This is part of an unfinished project I'm working in at this very moment. It was a happy coincidence that you were working in a noise generator at the same time. This file wont execute, because many routines are missing, but it will show you how to generate a .wav file. At some point in the routines, you should provide actual data. This data is floating-point, having any value. It is "normalized" afterwards in the "out" routine to the range -32768 to 32767, generating a .wav with 2-channel sound at 44100 Hz sample rate.
