problem with agal and Vertex

Oct 22, 2011 10:25 PM

i tried with pixel bender 3d  and hardcoding with the same result. My code for the vertex:

 

 

var

agalVertexSource:String="m44 vt0, va0, vc0\n"

 

 

 

 

 

 

                        "sub vt1, vt0, vc4\n" +

                         "mov op, vt1 \n"       +

                         "mov v0, va1\n";





_context3D.setProgramConstantsFromMatrix(

Context3DProgramType.VERTEX, 0, camTransform,

true);

 

_context3D.setProgramConstantsFromVector(

Context3DProgramType.VERTEX, 4, Vector.<Number>([0.5,0.0,0,0]));

 

All i want is a translation of the vertex (sub...) after the multiplication by a matrix (m44...). The result : the program translate the point and then multiply the result by the matrix.

    just to precise something else. If i use a second matrix just to tranlsate the vertex it works:

     

    m44 vt0, va0, vc0

    m44 op, vt0, vc4

     

     

    that's why i think there is something i don't know about the opcode sub.

    Hi Penael,

    Giving your vertex program a shot in my test program and I get the correct order of operations (matrix multiply first, then translation).  Do you happen to have a test that can show the issue for me?  You can post it here or email if to me directly at aaronc@adobe.com.

     

    Thanks!
