1k hires idea, adaptation of Grandpr1x
Re: 1k hires idea, adaptation of Grandpr1x
The drawing routine now is drawing each next turn as if you are already standing on that point.
However when the road is turning you need to draw fromthe point you will reach after the turn.
In fact you need to keep the vector from previous turns in mind to draw the next turn.
So after a left turn a straight road must be drawn straight, but in a left movement.
This means calculating a vector on each step and draw the road according to that vector.

A picture to show what I mean
Dots show position after 1 track, then rest of road is shown.

Still working on the correct draw of the track.
Routine doesn't crash, but isn't working either.
Quick thought about the screen.
When I invert the road I create a horizon without the costs of any memory

Single trackdrawing looks promissing. I need to add the doubletrack.
Some plotpositions are skipped over. Not much of a problem, but it would be better if all were filled.

Screendisplay is working, now I need to find the perfect width/depth mode in the display, but that is just a small formula.

At the cost of 70 bytes data I think I can add the racecar. This looks much better than just the road.
I will keep this in mind...

Wow! Brillant!
In theory, there is no difference between theory and practice. But, in practice, there is.
