Are you using a z buffer? By background image do you mean something like a skybox?

Could something like a large square of 2 tris made for the ground plane but repositioned/rotated around Y each frame to be centred below the camera work?

I have to agree it was quite a crippled system, probably one of the reasons I want to see if my rendering idea can be made to work on it, it'll be a challenge.

Thanks, yes, much nicer. Edited the code above to use that now.

This is a simple example in FB of a rendering method I came up with, I don't see it having much use these days but i'm attempting to write it for the old Electron. Arrow keys = left/right/forward type gfx_buffer wwidth as long height as long pixels as ulong ptr z as single ptr c as ulong ptr end typ...

Looks like you have other subs for setting and clearing flags too.

You should work on the assumption that everything you discover or think of, has been invented earlier by someone else. I invented a rendering method some time ago (at least in all my time obsessed with software rendering I've never encountered it), the results are similar to early Doom type games s...

Hi Paul, thanks for the suggestions. Language wise I was thinking of sticking mostly to the ASM possibly with some sort of additional way to deal with data structures, function calling and loops but that's not really high on my list and I'll just see what comes up as I go on with just an assembler t...

This is a bit of a strange project, my first computer was an acorn electron and there's something i want to attempt to code on it. I don't have the machine any more but I have the electrem emulator. Unfortunately it's a bit of a clunky system to code on so my plan is to sort of emulate it although I...

Come up with a data structure that contains the object data, something with a list of 3D vertices and a list of connections of pairs of those vertices for each line of the wireframe. The object will need a position and orientation in 3D space, so you'll need some sort of transformation matrix for th...

I have something kind of working now (in 32bit) and the effect is quite good even though its all pretty rough so far. The lag to the screen is there but it's not too bad but there seems to be a slight lag between the cameras, so when triangulating head position if I move my head to one side it think...

Thanks, and no worries, I can do it in 32 bit, it's just a test to see what sort of results I can get.
Got some coloured LEDs ordered, but now wondering if IR might be better, tried out an LED light and it results in bad reflection off screen, and with an IR pass filter it would be easier to track.

@Joshy thanks, I've installed the 32 bit compiler now and im_capture is working on that, both streams and not too much lag but I'm not sure how my project will work with even a little lag, might just end up with motion sickness or something.

i'm getting myself confused, i thought you were just trying to get the overloaded operator to work.

sorry, it was working, ive edited the code in my post above.

@albert, looks like it works, it was writing the value into i screen 19 type number i as integer orig as integer end type operator abs overload( byref n as number ) as integer n.orig = n.i return abs( n.i )' or n.i*sgn(n.i) end operator print "number" , "abs(number)" , "orig...
