“The PSX’s hardware only allow fixed point calculation so when the camera is moving or an object is moving, any given vertex stays in its position until it’s close to the next position and suddenly snap to it, nowadays graphics hardware can interpolate vertices between two position smoothly thanks to more floating point precision that is available.”
EDIT: This actually isn’t the correct vertex snapping technique for a PS1 style effect because it works in world space instead of view/screen space
I am using this exact technique for my game.
