Is there any open-source 3D graphics and physics engine specialized in driving simulation? Something like a configurable game engine targeted at games that involve driving, or something more specialized to urban traffic conditions and that would implement scriptable traffic rules. Also, car motor parts and

问题 I am programming a raycasting game using SDL2. When drawing the floor, I need to call SDL_RenderCopy pixelwise. This leads to a bottleneck which drops the framerate below 10 fps. I am looking for performance boosts but can't seem to find some. Here's a rough overview of the performance drop: int main() { while(true) { for(x=0; x<800; x++) { for(y=0; y<600; y++) { SDL_Rect src = { 0, 0, 1, 1 }; SDL_Rect dst = { x, y, 1, 1 }; SDL_RenderCopy(ren, tx, &src, &dst); // this drops the framerate

问题 I'm trying to use Bullet physic engine to create a 3D world. I've got my character with a Capsule shape on his body and my ground his made of some static blocs stick together, here is a schema to illustrate my words: The problem is present when my character run from one block to another: Bullet detect a collision and my character start to jump a little bit on y-axis. How can I avoid the problem? 回答1: What I did to overcome this issue is the following: Instead of have the capsule slide on the

Closed 3 years ago . I'm a relatively ok-ish programmer, but my main focus has been in application development with C# so far. I have almost zero experience with game development and 3d engines - I've begun reading up on how 3d Engines work in general, e.g. there was a wonderful guide explaining how

问题 Having recently switched to three.js as my renderer, I am now wanting to set up a system for mapping textures. However, I'm not too sure on what the best practice for this is. Here is my use case I have levels made of a lot of box geometries I need to be able to map a wide variety of textures to each face of each box geometry (grass, water, stone, rock etc.,) I would like to do this in the most efficient, performance conscious way as possible, so offloading this to the GPU would be best if
