Compotime: Show me your (vector)balls
After several comments arised that such an amiga-ball can be filled faster, i now want to call out a filler-compo for our coders.
Requirements:
The vector must be rendered in hires, background is white, foreground is dark red.
There's a raster-irq running that splits the screen at $2d and $f2 to set the background and border color to white and black, as seen in the screenshot. Means, there is a charline free in the bottom, that is where the benchmark results are displayed with the system charset. Displaying the result with screencodes is enough for us coders, but hex or decimal values are okay too.
The animation will be precalculated to see the power of your filler only. Therefore a data.bin is provided that contains all animationsteps for all faces with culling etc. already done.
The data structure may be altered to your needs, but not the animation itself, obvious isn't it?
The structure of data.bin is as follows:
byte x1 | $80
byte y1
byte x2
byte y2
byte x3
byte y3
byte x4 (optional, depending on if we have a triangle or quad)
byte y4 (optional, depending on if we have a triangle or quad)
As you can see faces can have 3 or 4 vertices, the first vertice is marked with bit 7 set, to be able to determine if a face consists of 3 or 4 vertices and to have a break out point for a finished frame, which is marked with the value $ff. If there's further questions about the data-format, don't hesitate to contact Bitbreaker
The filling must happen fullframe and fullsize, means, no interlacing or other cheap tricks with reducing resolution.
A counter for benchmarking must be implemented to count the frames until 256 frames have been displayed, it must be made visible in the bottom line.
The lowest value achieved counts (as there might be some jitter), for that, each entry must run in an endless loop.
The whole mem can be used, but every free byte of mem gives extra kudos.
Deadline is June 25th 0:00.
If the deadline is extended, a severe drama is expected, if not, you are out. Also i'll participate with an own entry, make a drama about it! :-)
Entries must be handed in to Bitbreaker and must not be released beforehand. They all will then released after the deadline, for maximum thrill and drama :-)
Each entry must be executeable with run.
SO DO YOU HAVE THE BALLS? |

We could also just all agree to run Vice at 400% speed. Why waste your time with nerdy optimizations when there's easier ways to get to the same result? :) |

@Groepaz: Damn, you have beaten me. My version runs in 50 fps on Amiga. |

@Axis & @Groepaz: Now please sit down and port Groepazens GL Version to Storm-C using GL on a plain A1200 mit 020er. My bet: 2 fps :D |

My bet: Wont start at all.
?Out of chipmem error
Ready. |

i have ported SDL with software GL before.... maybe we can use that? 2fps is mandatory for amiga afterall =) |

Yep, your bet is closer to reality I guess... Still I remember laughing my ass off, when I first saw the GL-samples with Storm-C back then. And that was 68030/50 already!

Yeah, I already knew that the topic is a typo by bitbreaker. He was supposed to call it: "SLOW me your (vector)balls". Damn you, Bierkeule! |

Well, i wasted a whole day on implementing the hard-liner.. and all i got was ~16 frames or so on 256 animation steps :(. Overhead ate my hardliner.. :P. Ok, now at least i have done it, perhaps i can reduce some shit somewhere.. But no matter what, i'm still generations behind Cruzer.. |
