But.. if other people tells it looks good, i gotta belive it looks good. Anyway, that's a
interesting idea and i'll gotta look in sources.
BTW: in article you tell you have looked at other sources about volumetric fog. Where they was from and where i can get them to take a look?

P.S. for what you have skins in textures dir (rat.pcx, for exam.) if there is no 3d models?

You can do a lot with this algo. Well, why a sphere, because it's easy to set up a scene with this, it looks great and calculating intersection is very easy.
As said in the article, you could even use 3D Meshes, and then you could create any effect you want (Volumetric Lights) or 3D Clouds and so on.

Well, a S3 Virge is not the 3D Card modern graphics are done for. Perhaps the S3 Virge has problems with alpha blending because that's used. Just check out the screenshots of the article, do you think that looks ugly, well that's what it's looking on 3DFX or Riva TNT. So, it's your S3 Virge. You can buy a RivaTNT for a few dollars now, so run to your distributor and buy one, I really recommend that !!

I wanted this article as fast out as I could. As you can imagine it makes A LOT of work to do something like that. So, I used the textures for testing purposes, and I simply forgot to remove them.

Well, this sounds as you did not select Direct3D HAL in the second ListBox. You will need to select Primary Display Driver in the first and Direct3D HAL in the second.
If you did that, please post another message. I will then try to put in a lot more Debug-Messages and send you the new executable, that will hopefully help finding out what's going wrong with you.

And to all people here:

THANK YOU VERY MUCH on your feedback. That's motivating. I got so much positive feedback, I never expected that. I am looking forward writing my next article.
Perhaps you can post a few ideas, what you always wanted to know.
The next stuff I wanted to do is Lightmapping with Power Render, cause I need that for my next game. But, this could take another 2 weeks, cause it's quite hard stuff. In the meantime I will perhaps write an article about Real Time Level Of Detail Rendering. This algo is nearly finished and this should make it quite easy to do the article.

Perhaps I also try to do another example which uses another object than a sphere, for example 3D Meshes for Volumetric Fogging, that'll be great.

Thank you very much.

Phillip

By the way : If you do any improvements to my example, please Mail me, I am very interested in seeing that.

Today I finished my article : Volumetric Fog with Power Render.

You will find:
- 64 KB HTML explaining every detail
- an executable demo
- Full Source-Code

I hope this helps.

Mail me, if you have comments or questions !
