don't worry, PhysX doesn't require a PPU card to run, and it's the best physic engine I've used, only Havok can compare with it.
A PPU card simply make it faster because if not all the physic is calculated by CPU, you can optimize it a bit using multithreaded programming on dual\quad core processors but in the most cases it's fast more than enough.
And.... Seems strange but it's also faster than box2d, the advantage of Box2d will be only on the crossplatform side, that i'm considering too... i'll see Smiley
Also, Ageia is now part of NVidia, and they're working to new drivers to have physics by GPU, so in the near future PhysX will be also hardware accelerated by NVidia graphic cards.

About the rendering-to-texture stuff, yes, it will be a lot faster with a pixelshader, you need to put a quad in front of your camera, then instead of using the backbuffer, render the scene to a texture, there are plenty of tutorials about that tecnique, on opengl or directx, just search around something about "render-to-texture opengl" or "off-screen rendering opengl" ( few links i just found: RTT with opengl
RTT with DirectX Wink).
After that you will have a texture of the scene. Then you can choose two way to do a filter: using a pixel-shader (called fragment shader on opengl), so rendering your quad with that texture on it using a shader, like I did, or locking your texture, changing manually the pixel values (the texture is a 2x2 array of rgb values). That's slower because you will be using the cpu, but compatible also with integrated chip or old graphic cards... and you can make it a lot faster using sin\cos LUTs anyway Smiley
If you're interested in it i can post some hlsl examples for a 2d pixel shader (maybe in an another thread!), and if i've the time, also how to do the same thing by cpu

I think after or before I will have to buy a better card that supports Pixel Shaders Tongue

Yep please, opening another thread explaining such things will be really welcome. I would like to see that bloom shader. But also the vertex shader for achiving such "toon" visualization.

Thank you!

Actually I would like that as well, I need to get some Direct X foo under my belt for next term.

*BUMP*




...and the robotic planet will host one or the races the player can choose from :)of course tiny robots.

moar news about what i'm doing and what i'm gonna do on my devlog http://www.0xdeadc0de.org/ (Circle related and not)I'll be happy if you leave a comment here or there as well Wink
I hope to have more interesting news soon and maybe something like a first teaser video Wink

Visually, it looks great, fantastic, perfect. Gameplay-wise, it sounds a bit like Dyson.

it's Dyson that looks like Circle, not the opposite, Haowan got inspired by this game for Dyson.

Man, just look the date when this thread was created....

to everyone, please: THE DISCUSSION HAS MOVED HERE, USE THE NEW THREAD! Thanks!  Smiley

Just to confirm that Dyson was inspired by Circle and not the other way around. Hope this doesn't happen often, sorry about that Eclipse!

Cison?  WTF Anyways the games aren't that similar at all, at least graphic wise. And gameplay-wise the similarity will be even smaller from what I know. Smiley No worries
