Colecovision with f18a vector graphics example

[+digress]

Very slow routine I programmed 

can draw lines any length and direction in any of 4 colours

required f18a for this version. would work on a standard coleco but i'm aiming to speed this up significantly

 

Anyways I thought it was pretty cool.

Cool stuff!   

 

Given that the line display is currently slow, I'm guessing you're calling the PIX routine for each pixel via the CPU, instead of running code within the F18A?

This is a new routine programmed from scratch running only on the z80

 

The pix routine i'm still having trouble with get to work. it works really fast but drawing incorrectly at the moment and causing crash on coleco. 

 

Need more time to figure that out then you'll see some fast vectors.

Looking forward to seing more! Keep up the good work!

Great stuff!

Maybe we could finally make Tac/Scan for CV with this technique...

the f18a gpu version  it'll be able to do that and more.

 

on a standard coleco it might not be much faster than this sample though.

That would be awesome
Tac/Scan is such a fun and underated game
