i am working in a hybrid OpenGL/DirectX 3D engine and i was starting to make a car game in which i want the camera to be always fixed on the player car my camera class has the 3 vectors loc,at,at which are used to update the graphics transfomation for both ogl or DirectX layers the camera At point, is getting update on a per famr basis according to the location of the car, and the loc, is just computed from it, by going backward in a certain direction, and the at vector is alwways 0,1,0 the problem is, some jumping occurs occasionaly, as if the car desont get rendred in the middle of the screen in some frames... the more the car goes faster, and far from the origin, the flickering problem is bigger i think this is happening due to floating pont error..but i am not sure i am sure many people faced this problem before...why it happens, and how to solve it?
