We can make some drifts ? Yes (by pressing 'd' to switch car behavior). Here is another demo, I made, powered by babylon.js : Demo
It's totally inspired by some demo using three.js. The next step is to add tire'skids and some particles to continue playing with thid great webgl engine. I'm working now on tire skids. My first solution works but it's very crappy & impact performances (add some texture boxes under tyres...). What is the best solution to display tire skids ? using shader to create some decals ?
Edit : For tire' skids, got something start working with shaders. It think it's a good choice.Finally, I use object pooling to create skid traces.
