Atari STE Blitter objects demo (new record)

Post by Anima »

After the video post on Facebook I just wanted to start another thread about the Atari (STE) Blitter here.

This demo is showing 23 32 x 32 pixels Blitter objects moving at 50 Hz on a genuine Atari STE:
https://www.youtube.com/watch?v=UotlGkgesbU

"New attempt with one more object: now displaying 23 moving Bobs (32 x 32 pixels, 4 planes) at 50 Hz (320 x 200 resolution) running on an Atari STE. Fun fact: we're reaching and surpassing the theoretically Amiga OCS Blitter speed limit (screen size: 320 x 200 pixels with 4 bitplanes)."

Will post some strange/interesting observations later on...

Great suff :) Blitter rulez. Too bad that it hadn't been used much on STe back in the time.

Hi Anima, is the original video post accessible without signing in to FB?
If so, can you provide a link?
I feel like I'm missing out on Atari stuff going on by not having a FB account anymore, I just kept ignoring content that was published on FB...

The discussion on FB is in a private group so I doubt that you have access without logging in and joining. The video, though, is the same as in the original post. ;)

Great stuff, you should make a small release / demo using it. But then people will have access to the precious code and secrets ;)

I never check other people's code because I find it really time consuming to try to understand code that's not mine and I have way more fun trying to devise weird stuff from scratch but in that case I might have a look to learn how the Blitter works, precisely because viewtopic.php?f=1&t=38994_ :D

I only noticed this thread a few days ago (and don't have facebook), although I did see the YT vid when it went up.

Anyway, it's pretty amazing! Are there any cycles left to play with there? Can't wait to see what happens next.

Thanks all.
I am currently waiting for my new PSU for the Atari STE due to some strange glitches while watching this demo. The glitches are visible within an one hour time frame after "cold starting" the machine.
