[Bf-cycles] Assign shader to a mesh

[haggi krey]

Hi,

following the standalone xml reader, I tried to create a shader and 
assign it to my mesh.
Is it correct that I add the index of the shader in the scene->shaders 
array to the mesh and to the created triangle?

For some reason I get an vector error in util_vector.h if I do it this 
way. ShaderId is set to my self created shader which can be found in the 
scene at index 4:

     Mesh *mesh = new Mesh();
     scene->meshes.push_back(mesh);
     Object *object = new Object();
     object->mesh = mesh;
     Transform tfm = transform_identity();
     object->tfm = tfm;
     scene->objects.push_back(object);
     mesh->used_shaders.push_back(shaderId);

     vector<float3> P;
     float3 p0 = { -1, -1, 0 };
     float3 p1 = { -1, 1,  0 };
     float3 p2 = {  1, 1,  0 };
     P.push_back(p0);
     P.push_back(p1);
     P.push_back(p2);
     mesh->verts = P;
     mesh->add_triangle(0, 1, 2, shaderId, true);

Any idea what could be wrong here?
