Hallo, Ich bin im Web auf folgende Seite gestoßen: http://www.zanir.szm.sk/dx10-19.htmlDort sind (meiner Meinung nach) sehr gute Shader für das Shadermodell 1.1 Beispiele: Parallax, Dynamical Cube Mapping und Motion Blur. Ich kenne mich nicht besonders gut mit Shadern aus, aber ich glaube nicht, dass sie in HLSL geschrieben sind. Trotzdem lohnt sich ein Blick darauf. // Hello, I found this site in the WWW: http://www.zanir.szm.sk/dx10-19.htmlThere are some very good model 1.1 shaders (after my opinion). Examples: Parallax, Dynamical Cube Mapping and Motion Blur. I don't know much about shaders, but I think they are not written in HLSL. But give it a try. Greetings

Thanks for this great Link! vs.1.0 // version instruction
// c0-c3 contains composite transform matrix
m4x4 oPos, v0, c0 // transform vertices by view/projection matrix
// v2 texture coordination
mov oT0.xy, v2
mov oT1.xy, v2
// c4 lpos
// c6 eye
// H = HalfVector = Normalize( VertexToEyeVector + LightVector )
add r0, c4, -v0 // L = lpos - vertex, L in object space
add r1, c6, -v0 // VertexToEyeVector
add r0, r0, r1 // HalfVector
// v3 Tangent, x
// v4 Binormal, y
// v1 normal, z
// matrix for object space to surface space
// ( Tan.x Tan.y Tan.z ) = ( v3.x v3.y v3.z ) ( L.x )
// ( Bin.x Bin.y Bin.z ) = ( v4.x v4.y v4.z ) * ( L.y )
// ( nor.x nor.y nor.z ) = ( v1.x v1.y v1.z ) ( L.z )
dp3 r1.x, v3, r0
dp3 r1.y, v4, r0
dp3 r1.z, v1, r0
// r1 H vector in texture space
// normalize vector in r1
dp3 r1.w, r1, r1 // r1.w = |r1|^2
rsq r1.w, r1.w // r1.w = 1/sqrt(r0.w) = 1/|r1|
mul r1.xyz, r1, r1.w // r1 - normalized L vector in texture space
// <-1, 1> to <0,1>
// c5 0.5, 0.5, 0.5, 0.5
mad oD0, r1, c5, c5
This doesn't look like it is gamestudio compatible... Does anybody now how to convert these shaders? Dark_Samurai

 I've never saw any asm code ^^ Can you convert this shader as example for me, so that I can convert the rest my selve, please? Dark_Samurai

I looked up asm in the manual. It should work in the engine. Example: material test { effect = " asm { vs.1.0 // version instruction m4x4 oPos, v0, c0 // transform vertices by view/projection matrix // v0 - pozicia vrchola // v1 - normalovy vektor // c0-c3 contains composite transform matrix // c6 pozicia kamery v suradniciach objektu // c7 -2,-2,-2,-2 // inline vec ReflectedRay( const vec &in, const vec &n) // in from eye to vertex // return (in - 2.f*n*DOT3( in, n)); add r0, v0, -c6 // r0 = in = vertex - eye // normalize vector in r0 dp3 r0.w, r0, r0 // r0.w = |r0|^2 rsq r0.w, r0.w // r0.w = 1/sqrt(r0.w) = 1/|r0| mul r0.xyz, r0, r0.w // r0 - normalized in vector // DOT3( in, n) dp3 r1, r0, v1 // r0 = in, v1 = n // n*DOT3( in, n) mul r1, r1, v1 // v1 = n // in - 2.f*n*DOT3( in, n) = f = r1 mad oT0.xyz, r1, c7, r0 // r1 = r1*c7+r0 //... } "; } Just a suggestion. I'm a shadernoob  . That should be cube mapping Look it up in the manual, just type in asm.

Ok this is what I got so far (specular normalmapping): technique NormalSpec
{
pass P0
{
VertexShader =
asm
{
vs_1_1 // version instruction
// c0-c3 contains composite transform matrix
m4x4 oPos, v0, c0 // transform vertices by view/projection matrix
// v2 texture coordination
mov oT0.xy, v2
mov oT1.xy, v2
// c4 lpos
// c6 eye
// H = HalfVector = Normalize( VertexToEyeVector + LightVector )
add r0, c4, -v0 // L = lpos - vertex, L in object space
add r1, c6, -v0 // VertexToEyeVector
add r0, r0, r1 // HalfVector
// v3 Tangent, x
// v4 Binormal, y
// v1 normal, z
// matrix for object space to surface space
// ( Tan.x Tan.y Tan.z ) = ( v3.x v3.y v3.z ) ( L.x )
// ( Bin.x Bin.y Bin.z ) = ( v4.x v4.y v4.z ) * ( L.y )
// ( nor.x nor.y nor.z ) = ( v1.x v1.y v1.z ) ( L.z )
dp3 r1.x, v3, r0
dp3 r1.y, v4, r0
dp3 r1.z, v1, r0
// r1 H vector in texture space
// normalize vector in r1
dp3 r1.w, r1, r1 // r1.w = |r1|^2
rsq r1.w, r1.w // r1.w = 1/sqrt(r0.w) = 1/|r1|
mul r1.xyz, r1, r1.w // r1 - normalized L vector in texture space
// <-1, 1> to <0,1>
// c5 0.5, 0.5, 0.5, 0.5
mad oD0, r1, c5, c5
};
}
}There are a lot of errors like this one: "(13): error X5326: Read of uninitialized components(*) in v2: *x/0 *</1 z/2 w/3". What am I doing wrong? Thanks!

Thanks for the salutary site Timothy  Although, most of the effects on that site that I've seen on there are written in asm and since asm is a 'harder' to grasp than HLSL, I would advice not to start learning asm but HLSL  Cheers Frazzle

I don't want to learn asm, I only want to get these shaders working in GS...
