Racing AI (with complications) Having read through some of the other racing AI threads on these forums, I've noticed that most of them involve creating an AI that follows a developer-specified optimal racing line. But my tracks are hideously loopy: My Journal, for Screensh...

Help creating arcade racing simulator Okay, so despite my best efforts, I seem completely incapable of coding a simple driving simulation. It doesn't have to be super physically accurate, but it has to feel correct. I've read the Physics of Racing articles (which are, sadly, slightly o...

Three-wheeled Vehicle Physics I'm having trouble with my vehicle physics, and I'm having an insanely hard time finding any resources that have proven useful (For instance, the "Physics of Racing" series is almost too in-depth, and try as I might I've been unable to take the ideas...

Friction vs. Torque So I have a program where, ideally, I can roll a ball around by applying a torque around the axis. So I have two functions: EDIT: It should be noted that "^" is my cross-product operator. void AddForce(const CEVector3 &f, const CEVector3 &poin...

Trouble Designing A Bezier Terrain Editor's Interface So I'm trying to make terrain out of cubic bezier patches, but I'm having trouble coming up with an easy-to-use interface for the editor (though the engine works just fine). So far, what I have basically allows me to select a patch and move indivi...

Bezier/Ray intersection Is there a good, fast way to calculate the intersection between a cubic Bezier patch and a ray, without making the bezier into mesh and generating a quadtree of bounding boxes (with quads as leaves)? Google hasn't been my friend in this regard. The...

Bezier Patch Modeling First, some background: I'm not an artist. Well, not a very good one anyway. I'm a programmer, mostly. I've written a "square" cubic bezier patch rendering engine for a game project (of course), but I hate the modeling interface I've come...

Cracks between bezier surfaces of same LOD This has been bugging me to death for a while, and I'm afraid it's just a floating-point round-off error in the shader, but I figure I'll ask anyway. I'm getting small (usually 1 pixel) breaks between bezier surfaces that are being tesselated at t...

Gigastudio I’ve heard some things about a program called Gigastudio. I’m thinking about getting it, but it’s a mite pricey, and there’s no real way to demo the program beforehand. Has anyone used it? What’s the interface like?...

The Daily GameDev.Net Definitely second the whole "why the <insert favorite expletive here> did they de-color the Xbox buttons?" thing. How am I supposed to tell my wife which button to hit in games now? "No, sweetie, hit the gray one. No, the other...NO THE...

[FILLED] Cover/Poster artist for space shoot-em-up game Quote:Original post by qCring Yeah, that looks really nice! But I would suggest you to redesign some things, like the model of the player´s ship and maybe even the alien-ship models. Don´t get me wrong, but take a look at some spaceship models out...

GetTransform in D3D10 Direct3D 10 doesn't have a fixed-function pipeline, which is what those transforms were used for, so no, it doesn't have an API like that. Instead, you set your transforms as shader constants/effect parameters. Since you were the one that se...

Multisampling: What's really going on First, the shader (or FFP) runs once per pixel. Once this is done, this polygon has Color and Z/Stencil information. You are correct, this is calculated once. Then, for each multi-sample sample in the render target (i.e. four times...

Matrix mul on CPU or GPU? (dx10) Also, something to keep in mind: With vertex shaders (and pixel shaders, too? I'm not sure), if you're using the D3DX FX framework (and maybe even if you're not, I'm a little fuzzier on this point), the compiler can (and does, by default, I...

[C#] [XNA] Bizarre bug when using ResolveTexture2D The issue is actually really simple: when you render to the screen using your quad, you're rendering to a render target that has antialiasing (MSAA). Because of this, you're getting a border due to the dreaded half-texel offset issue that is general...

[C++/DX9] Temp fonts for game Also, D3DXFont converts your TTF to a bitmap font internally, so you'd be: A. Saving a TTF processing step and B. Simplifying your game's distribution (By not needing to dink around with Add/RemoveFontResourceEx or distributing the .ttf, you'd j...
