- @smash: I noticed :)
Will you do the commentary? ;) - isokadded on the 2009-08-10 05:44:21

- Thumbs up from me for the car part and the low-res projection in the middle. And the fluid sim even if it couldn't be integrated properly. Looks like it deserved to win.
But why do I get the feeling it's essentially Media Error 2.0? - rulezadded on the 2009-08-10 05:38:12
- 64k MS-Dos TANTRO by Hornet [web]
- Yeouch, I'm not sure I could live with myself with so many unrolled loops :) The only unrolled loop I have is 40 instances of the above snippet, for a single 80-byte-wide scanline. But that's an interesting concept, thanks for sharing it.
Someday I'll write a full-fledged 8088 demo with at least 10 effects... I may be bothering the C64/CPC/speccy people when that time comes ;) - isokadded on the 2009-04-26 18:14:13
- 64k MS-Dos TANTRO by Hornet [web]
- Exin: The routine is as optimized as it is going to go; most people don't understand how slow 4.77MHz machines really are. Memory access times are so bad (4 cycles per byte, including opcode fetches) that a 4.77MHz 8088 is slower than a C64. I'm not kidding.
Here's the inner loop of the rotozoomer:
add cx,SI {ddx}
add DX,bp {ddy}
mov BL,ch {bx = 256*int(y)+int(x)}
mov BH,DH
mov al,[BX] {load a pixel from source}
{next pixel}
add cx,SI {ddx} {add the 'right' vector to the current}
add DX,bp {ddy} {bitmap coordinates. 8.8 fixed point}
mov BL,ch {bx = 256*int(y)+int(x)}
mov BH,DH
mov ah,[BX]
stosw {copy, advance to next dest. word}
All variables are in registers; writes to video memory are done at the largest machine size word (STOSW). It took me a long time to get things that optimized, so if you think you can do better, I would love to know how. I know I'm not the best coder out there, but this was one of the few effects I was proud of.
I will say this: My music routines need optimizing :-( It's faster without music playing.
Final version with source will be released in a week or so. - isokadded on the 2009-04-25 02:42:01

- For everyone getting GRAY VIDEO and NO MUSIC, you need to set machine=tandy in dosbox.conf. Please do that and *then* comment :-)

- 64k Windows please the cookie thing by Aardbei [web]
- That's a really impressive softsynth for 2000. Hell, even for today (I get a kick out of human-sounding voices in softsynths)

- demo Amiga OCS/ECS Extension by Pygmy Projects
- A ton of great ideas, which is always hardest part.

- demo Windows Into the Pink by Plastic [web]
- Yes, demo is dark at the beginning, but you should still be able to make out the two scenes. If not, then you've screwed up your MPEG-2 encoding colorspace conversion! Enjoy!
If you kkapture Into The Pink with full quality full AA turned on, one of the scene doesn't render properly and all you see is the lightmap. Fun! So if the caterpillars falling down the shaft look red/orange/multicolor, back you settings down (or back off of the LSD). - rulezadded on the 2009-01-13 06:28:46
- diskmag Windows Hugi #35 - Disruption in Chaos Theory by Hugi [web]
- Minus that completely racist out-of-place-for-a-demoscene-mag article, I thought Hugi #35 was okay. Not great, not mind-blowing Imphobia-class fantastic, but okay. Some of the articles are worth reading.
I don't get hung up on the interface unless it gets in my way, so I didn't find the interface all that big a deal. It's the content I care about. - sucksadded on the 2008-11-09 01:12:58
- intro Apple II Brazil by Hackerforce
- Needs new screenshot; the main screen is designed for monochrome.
