@Omer:

what FPS do you get with the water shader ?

also did you fead many parameters for shader program ?

good work.

without the shader its about 35 fps with the shader its 23 fps

i fed the time and a csutom matrix i use for projection

It is possible to do the physics completely on the gpu but i need results from the previous cycle, this can only be done via a vertex texture lookup where results from a vertex/ pixel shadera are stored for futre use but that needs a geforce 6XXXX card

to get around the ati bug im now converting my shaders to assemble using cgc.exe, however the output isnt perfect and needs cleaning up but at least it will the sahders will work on things like geforce 3 and all ati cards with shader suppourt

Omar, are you using any multiple pass shaders for any of these? I would be interested in getting a grass shader working if you could tell me your trick to using multiple passes.

I saw in one post that you said you were gonna make it available for even shader 1.4, if this would work with ati shader 1.4 then it wud be really really gr8 coz then it wud work on ma pc!

Hello, is there any updates in your shader program? Oh yes, it'll be great if you can share the source

and i wan to test your demo!

hehe sorry for not replying for so long.
I may have a demo soon, the water shader on the other hand will be redone to feautre parallax mapped water, however the vertex shader component will be the same.

Any source release or anything new?

Here is a test water shader with hardware accelerated waves, illusuion of depth,frensel, refelection and refraction.

EDIT: select the bumpmapping shader form the list, i forgot to label it properly

I havent implemented the timers yet so its not animated, and the projection code is another project, but this little demo shows the looks side of the water.

I would like to combine this with katoun's water sim to have really cool water with physics.

move around and see the illusion of depth, mess with the texture for diffrent wave shapes etc....

doesnt require tangents and such.

its in gl asm so it should work on old ati and nv cards

ill relase the source when the whole water shader is complete

i hope this cheers ppl up, some ppl left irrlicht because of the lack of water. I hope this cure their thirst
