Pictures seriously encouraged.


Started a couple nights ago, can you guess what it is?


The beginning of a software renderer because proper 3d graphics in my stuff would be neat I thought. Actual polygon rasterization will probably come later, but wireframe stuff seems simple.

Currently it's at the state of "SOME MATH APPEARS TO BE FUCKED SOMEWHERE" which really isn't surprising, though I think I have most of it understood (read: no, not really). The matrix stuff is pretty confusing, but I'm pretty much basing it off the D3D pipeline (and gamedev articles) so I have some kind of direction to go in.


I already wrote something a little while back that will blow through a .obj file (3d obj, not linker obj) and output an even more dumbed down file for me to read directly. Once I have it drawing correctly, loading any model should be easy.

It's a dot, a dot in the wrong place, but a dot nevertheless

one day it will be something a little more beautiful.

I'm making an asteroids-like game in Java with LWJGL :]
I have a few of your sexy dots and a sexy moving square!

I've been working on and off on a 2D particle system. So far the only thing that's been a concern is the amount of calculations needed for each step in the particle trajectories. I wont know if it's a real problem until I have a working product though, so I guess I'll just have to cross my fingers. Nice thread by the way.

I doubt it will be too heavy, but even then you can take shortcuts like limiting the amount of times the simulation is run per second and interpolating from there.


I'm trying to wrap my head around all the matrix math for this renderer, specifically the projection / transformation stuff. Fun (read: mind crushing) stuff.

Quaternions will be a bitch for you then. Wink

If you need help with any of the theory (linear algebra or otherwise), just send a PM my way. Bear in mind, it may take a day or two to get back, as I don't check this site as often as I did.

I'm currently creating a bot for silkroad online russian version.
So far I made send,recv hooks to the game, analyzed the packets, created the packet analyzer so the bot understands the packet size and what action is coming from the server, some little decryption that had to be done to send a successful packet to the server, object distinction so the bot knows if a player/mob/npc/item is appearing, a list of available mobs around and some AI. So far the bot can still only attack and switch between mobs, but I'm working on it. It's the first time I make a project like that, and it's very hard for me..

Ah, yeah, I'm hoping to pick up the math as I go along.

I have it in a somewhat working state now, I don't have any form of line drawing in right now so it's just verticies and I think I have some math problems lingering but it does indeed display 3d right now, seemingly somewhat correctly.

It's first object was a 3d cube that rotates. I'll post it sometime later tonight maybe.



edit: except for one pos thing I can't seem to figure out. I seem to be eventually squashing my objects into nothingness after some time of rotating... not entirely sure how to handle this yet, but i seem to be eventually destroying my matrix through rotation.

edit again: figured it out and it turned out i was being retarded. think i've fixed everything now... all it needs is a line drawing routine and it's golden.
