Hi,
I have implemented program that renders simple 3D scene in real-time on the CPU. Program requires CPU with AVX2 and FMA3 instruction sets support (Haswell and newer). It takes about 25 ms to render one frame on Haswell i7 (40 FPS). Screenshot and code attached.

Very nice - i get 16fps on my dual core HT lappy.

Unhappily my cpu don't support AVX2 and FMA3. I'm sad.

Code: Can I ask what are you working on currently? No much - I am too lazy these days to do too much programming. I am slowly building a chess gui+engine. Would you like to see the code for the program that made those movies? |

When fasm compiles it doesn't use any instructions beyond 80386. So fasm can always compile even the newest instructions as long as your CPU is 80386 or later. |

I am adding the mandelbox code to github. It is probably incomplete and some of the comments might be wrong,
but you can compare how I did some things. https://github.com/tthsqe12/mandelbox I'm currently working on some dense algorithmic programs and have switched to c++ now that I have understood that compiler. I hope this board doesn't view me as a traitor. |

Yup. Crashes here too. Something isn't supported I guess.

Hi, Randall:
It's very cool, but it will crash in my win7 64bit os. it seem that the WIN64 program need align the stack address to quard word align before executed call instruction. You only added align instuction into the source code, but it only work in complier time, it can't sure that it's okay in the run time . So it will crash sometimes in WIN7 64bit OS. Thanks.

I have uploaded new version that:
* Displays error message when AVX2, FMA extensions are not supported. * Creates X threads where X is equal to the number of logical processors present on the machine. Thanks, Michal |

Kenneth Zheng,
How many FPS do you get on your machine? Thanks. |
