Retro style 3D graphics

Postby BasicCoder2 » Oct 09, 2018 8:55

This is a 3d scene of a desert with a cluster of bushes.
You can move about with the arrow keys.
You might like to try key [A] or key[D] to see the effect of changing one of the variables.
Note: It requires multiput.bi which I just keep in the inc file of the freebasic compiler.
The two bitmaps required are generated by the program from data statements.

@BasicCoder2 for simple image/sprite scaling (without rotation) I posted other faster codes also.

Code: Select all

Scale and Put:

part of Screen [scaled] to part of [scaled] Image

You have W,H as single, but you integer divide
Should be
H = (pointY1-240)*2
W = H/9
H = H/9
I reckon.
