   Transform Vertex Coord: How?
  Hello,I want to transform my vertex coordinates into a specific position (e.g from (0,0,0) to (5, 0, 5) ).I did like that (which doesn't give the needed results):verts.x += pos.x;verts.y += pos.y;verts.z += pos.z;i tried to use matrices. No luck:transform.Identity();transform.Translate(pos);for(int i = 0; i < numVerts; ++i) {Vector3 newpos = transform.TransformVector(Vector3(verts.x, verts.y, verts.z));verts.x = newpos.x;verts.y = newpos.y;verts.z = newpos.z;}this gives quite unexpected results. How can i do?
  Both of your examples seem correct; what kind of 'unexpected results' do they produce?   ;  in my app, the pos value is set to Vec3(5,0,8). With matrices the 1st vertex (haven't watched others) translated from Vec3(1,2,-1) to Vec3(2,2,-1). But with just adding positions (the 1st one) it is translated to Vec3(6,2,7). after thinking a little bit about that i think the Vec3(6,2,7) is correct because its just one vertex of a cube. What do you think? Am i thinking correctly?   ;  You cannot translate 3d vectors with matrices. You have to use 4d vectors with the 4:th component = 1 (homogeneous coordinates).;  Oh. Code solved. it just forgot to add the last parameter to y and z values :DThank you very much for your help!
