I need a whipping fast algorythm to render a bitmap to a 3D plane. I know
about the 3D engines but I think it is overkill for what I need.
The idea is to project a bitmap on a horizontal plane. The camera view
should be allowed to be positioned at any elevation pointing at any
direction but will not bank.
There is no Z ordering as there is only the one bitmap to be projected on a
single horizontal flat face.
Does anyone know of references to material, code that can be used in Delphi?
Thanks

Have a look at projective transforms in Graphics32. You specify 4 corner
points A, B, C, D of your bitmap and it gets rendered in that area.
You can calculate the 4 points using an isometric transform or perhaps a
perspective transform if you want a tad more realism.
The transformation itself can be done with various quality settings. In
general, Graphics32 is lighting-fast doing these.
Kind regards,

Smack <Bengs on forehead>of course! I even had a play with that code not so
long ago. Must be getting old.
Thanks Nils.
