   Drawing the 0,0,0 point of a 3D mesh
  Hi guys,I got another easy one for you. Hehe ;)My mesh, which is a big room, has a point 0,0,0 like any meshes (I think!). I'ld like to "project" this point on my screen so that I could draw a circle and write down that the point of origin is here. I'm building an editor with the X/Z axes and working in negatives and positives, so the 4 zones. The point 0,0,0 of the room (big mesh) will be use as the point 0,0 on my screen.I don't know if I'm clear on that, I'm having trouble expressing this problem in english (I'm french).But bottomline, I would like a fonction that receives a mesh and throws me a CPoint which contains the x,y of the mesh origin coordinates.I'm guessing I'ld have to do a projection that will project a vector that would "get throught" the screen...this should be really simple, but I'm trying to figure out how...Thanks for any help :)Bbs   
  Use D3DXVec3Project.   ;  Nice! It works like a charm :)Thanks a lot ! I know it would be only a stupid function ;)
