Scaling Images In Polygon

hi.
I am a bit new to graphics programing. I am trying in vb.net to make a
3 walled structure which'll give the look of 3d. for that purpose, I
am using same rectangle filled with textured brush for 3 walls. For
the center wall rectangle is to be drawn as is. For the side walls,I
need a prespective plan view, so the rectangle and hence the images in
textures should be scaled like in a trapezoidal fashion.
But matrices and Drawimage transforms only provide for uniform scaling
in form of parellogram, but not a non-uniformed structure like a
trapezoid.
Is there any way I can do it in an effective and smooth way.
 
Hi,

I would suggest looking into managed DirectX instead.

If you Google 'managed directx' there are some promising results

Why not use DirectX for this purpose?

Thanks for the tip and I'll be going for managed directex and
downloading its sdk..but is it not possible in simple GDI+ interfaces
to .net framework? It provides for scaling images in parellolograms
effectively..and fast..so i was wondering weather there be a modified
DrawImage()function which would map to a polygon which is not
parellelogram. I wanted to keep things simple :-)
