3D engine

Anonymous — Fri, 29 Aug 2014 20:36:39 GMT

Hello there,

ok, here we go, I have a dream, make a 3D engine 100% assembler intel only with CPU, I use rotation matrix only for now.

it works of course, but it's slow when I put a lot of pixels.

Recently I decided to include voxels in my engine, and it's slow when I put> = 8000 voxels (20 * 20 * 20 cube) and when I saw that nvidia display 32M voxels (fire) I wonder how they can do it !

And I have a little idea of the reason: MMU, paging, segmentation. memory.
Am I right?

Another question, is the FPU is the slowest to compute floating point and SSE is the powerfull ?

PS: I work without OS like Windows or Linux, I run on my own kernel + bootloader in assembly too with NASM.

Sry if i don't wirte a good english, i'm french and use google translate ^-^

And i use a pointer on VESA

And i use a pointer on VESA LFB for draw pixel.

Another question, i don't think understand what is the gpu into cpu intel core, i have this processor: http://ark.intel.com/products/53464/intel-core-i7-2640m-processor-4m-cache-up-to-3_50-ghz.

And have AMD Radeon HD 6470M like graphics card, so can i theoricaly switch gpu ? if yes how do it ^-^.
Cuz i can't do it throung software: Windows Xp :(

Finnaly i want talk about mutlitasking method, i know modern OS use pagination memory for do it, but honnestly i hate this fragmentation of memory (RAM), so can i use my 2nd processor like a selector of code.

I mean this 2nd processor can have a personal memory who is fill by physical address of my program/task into RAM ? and every each sec for exemple, this 2nd processor jump to the next taks's address, and for execute it, he tell to main processor to jump in the address.

I know, if it's possible i would need a personal memory into RAM, so i will delimit at ADDR_TASK_END and ADDR_TASK_START like "segmentation" do it, but i think is more understandable and easier to learn multitasking and don't use "powerful" segmentation ^-^

What do you think, is it possible ?
