This is a 3D raycasting engine that can fit entirely inside the boot sector of a floppy disk. As a result, the program is exactly 512 bytes large, uses no floating point arthmetic, and, in a strange ...

RayCasting - technique in computer graphics that allows you to create 3D projections based on a 2D plane. This technique was particularly valued in an era when the processing power of computers was ...

Abstract: We present ForceCtrl, a novel 3D hand raycasting technique that enhances pointing precision based on control-display (CD) gain controlled with user-defined pinch force. We introduce a target ...
