Biggest problem with raytracing is the current lack of GPU acceleration - all that untapped power pissed away.... (FYI: A modern GPU can do significantly more calculations per second than your CPU can) |
we're getting there and of what complexity was the raytracing? _________________ StickFigure Graphic Productions || VSHI: Vermont Sustainable Heating Initiative

A bit offtopic, but speaking of GPU utilization, I believe I saw a recent article on Digg about a Mac image editor that had built-in sharing of the image processing load between the CPU and GPU. _________________

Single car - of course, it had all the typical stuff. Dynamic lighting, reflections/refractions, etc...
They had a video of it - I think it was on youtube.

Even with the GPU, I don't think we are at the point where we can get reasonable speeds with raytracing in something like a shooter, where there can be hundreds of objects on screen at one time, almost all in motion.
I did some "Digging" and found links to a. a 26 year old who made an experimental version of quake3 that uses raytracing, and also to a group of researchers who developed more efficient algorithms for it, and are making raytraced versions of quake 3 and 4 (and also, it said that these algorithms are going to be used in openrt) These will really take off once quad-core becomes the norm and gpu's are used effectively. _________________ Any fool can use a computer.

Of course not, but you are underestimating just how much speed is available in a modern GPU. Not nearly enough for raytracing currently, but GPU power is roughly doubling with every generation - not something the current CPU market can boast. _________________ There are only two kinds of programming languages: those people always bitch about and those nobody uses.

Take a look at this: http://medvis.vrvis.at/projects/visualization/
I had no idea raycasting could be used for such detail (and yes it uses the gpu Klr, its not raytracing, but still amazing).
I was doing some research on raycasting and such on Gamedev and the internet in general when I stumbled upon this (I've become interested in raycasting and raytracing now, thanks Calc84! ) _________________ Any fool can use a computer. Many do.

I'm making the sprites for my game right now. Would you, Kerm and/or rivereye (I guess only Kerm, since it's ASM), have anything wrong with me posting them when I'm done? I'm fueled by outside motivation, and I daresay I need it with at the pace I'm going at. _________________

Oh god! Sudden and random inspiration through a warped mix of Ngame, Mario, and Fallup =P
Not very original, but I need something to keep my basic skillz at a reasonable level =P _________________ Any fool can use a computer. Many do.

As I found info about on internet, it is different sights on where the limits or requirements between a platform game and other games. What is the absolute limits and requirements for the platform games in the contest  _________________

basically, if you jump from a platform to platform, and have side scrolling in some way, you should be good. _________________ I am the eye of the river

Does vertical scrolling count cuz that is my current idea. _________________

Yeah virtical scrolling will be easier for me to do. _________________

It is a cool idea (I know what it is). I was doing something similar to what he's doing, but I didn't want to spend hours and hours agonizing over a smooth-scrolling (on both axes), collision-detecting tilemapper, so I gave up the idea. _________________

Well i actually changed my idea a little because the first one wasn't much of a game so I reworked it using an idea the Tari was going to use. _________________
