cloth shader and shader 3 0

[Shargot]

hi all
i have some questions
1) tv3d support sm 3 0 ?
2) i find d3d9 cloth shader but i dont know how To force it to work.
may be some one help me?

this link to shader http://http.download.nvidia.com/developer/SDK/Individual_Samples/samples.html#Cloth

1) Yes, it supports up to ps_3_0 and vs_3_0.
SM4.0 (Geometry Shaders) requires DX10 though, so it doesn't support those.

hm... but this shader requer 30 model.

***
This sample demonstrates how to use Shader Model 3.0 to simulate and render cloth on the GPU. The cloth vertex positions are computed through several pixel shaders and saved into a texture. A vertex shader then reads these positions using Vertex Texture Fetch (VTF) to render the cloth.

i am download this shader. look at source and saw what it use directx9... also this site have directx10 cloth shader...

when i run this sample i have error... but my video card not support sm 3 0 and my card not nvidia... (ATI Geaforce FX 5200)

You realize that TrueVision can only do Shader Model 3 if the videocard supports it, right? I mean TV is good, but it's not voodoo. If you don't have a Shader Model 3.0 videocard, you're not going to get a Shader Model 3.0 shader working in anything.

Incidentally, there is no such thing as an ATI Geforce. The Geforce FX5200 is an Nvidia card, and it's definitely NOT shader model 3.0 compliant. 2.0 if you're lucky.

i kniw this....
but this is my home computer....

i also try this shader on computer with geforce 6 series with tv3d... and i dont know how do this...
my question consisted in that this shader will work on tv3d and as it to make?
sorry for my language.

It is ofcourse possible to use this shader in TV, but it needs quite some work, especially because it uses VTF (Vertex Texture Fetch) and this feature is only supported on SM3.0 cards from nVida and ATI HD Cards (2000 and 3000 series). I never used VTF, but Waterman has opened a topic about it lately, so he may have some tips about how to do VTF in TV3D.

thanx
i will search forum
