My maths is awful.
I last did matrices when I was 15 at secondary school.
I didn’t even pay very much attention.
I now regret this.
Help!
Who might be able to give me a ready made projection matrix which will give me that pseudo-isometric view we all know and love from the days of the Spectrum?
The matrix should work given a particular width and height of screen.
Origin at 0,0 should be in the middle of the screen. X coordinate goes right and down half as much; Y coordinate goes right, and up half as much. Z coordinate is simply added to Y coordinate.
If I could just remember how to multiply matrices I might be able to figure this out for myself…
