WEEHEEEE oh, oh wait its dead, I thought it was dancing (CRE8OR NOTICE)
cooldude234:
I find it interesting to note the cre8or site is back up and running by kappax (Keith Tabert is his real name),
apparently hes working on a new game which is also on kickstarter.
www.cre8or3d.com
www.kickstarter.com/projects/wak/outeredge-voxel-based-fps-sandbox-survival
So that's what he sounds like, well its good to see hes actually alive :P
makes me wonder if he's seen what I've been doing... *runs*
EDIT: it's down again and now some weird nonsensible post

Hello again Cooldude. We had such fun with the 3d calc last time, I thought I'd chime in again. Actually, just wanted to say that if you google "line plane intersection code" you'll a few useful hits. Easier than me typing it all out, anyway.
I may be a bit old school in terms of my gaming, but because collision detection can be quite computationally expensive there are a couple of tricks that tend to be employed to reduce the number of calculations.
Invisible bounding boxes around objects. Where each detailed model has an invisible, crude model associated with it that is used for collision detection. doing precise collision detection on a detailed 10k+ model is far more expensive than for a 500 poly blocky model, so it kinda makes sense. You see this in games all the time, where you can see a bullet's tracer missing/hitting something very clearly, and the game reacting to it wrong - what you don't see is how the bullet is striking the bounding box.
When shooting through objects games like railings or chain link fences, games will often treat the whole object as a 2 poly collision object and roll randomly to see if the bullet goes through unimpeded. E.g. the alien robot zombie is behind a metal railing, the bullet goes through railing space, then the enemy space, so at the railing space there is a 10% that the bullet stops. Rather than going through the expensive calculation of detecting the space of each rail individually.
Do an initial calc of which objects are even in the right area/direction and if they're not then don't even bother trying to do collision detection. Just makes sense, but it does need to be done.
You probably know all of this already, but I thought I'd just add it just in case. If you are having trouble with your frame count, then proper collision detection can have a pretty significant impact.

Well for me the kickstarter is still up, and cre8or3d is down, but http://outeredgethegame.com/ is still up (his game website), weird how it expired yesterday :P
Water Music, I know quite a bit about the concepts of collision detection, its more or less the math side of it that gets to me :S
And I know what you mean by the expense of some methods, but trust me I'm not wanting to do box collision on the whole world, now would I, besides I know how to optimize collision detections so I can make it even faster.
As for using Google, I'm on page 5 looking through every link, and still don't understand these line plane intersections.

Oh my... what the... what is going on here?!?
Man you just made my day! I am an anim8or member from 2004 (?). I was watching the progress of cre8or day by day, hoping that something great will emerge... can you imagine my disappointment when I saw cre8or, then Polly, and finally anim8or ceasing development? So much time... It was enough for me to learn C++, OpenGL, linear 3D algebra!
And after those years, I finally realize that something, someone is still alive (or undead? :P) and working! Believe me, I want this to work.
If only I could be of any help... however I will be making a 3D elementary game till Christmas, so I will be 100% busy till then. But I really wish that after that I will be here, watching the progress, giving any possible support.
Please make this happen :) Ah, now that I know there is still hope I'm not leaving that easily! I'll be around until then.
Very happy to hear from all of you people.

Grass!
Yes Grass (with a capital).
Its been a while and I think this was a worthy screen shot,
so here's an update of the grass I was working on.
EDIT: also its anti-aliased at 16x
