A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

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

This project implements a simple raycasting engine using algorithms similar to those in Wolfenstein 3D to generate a pseudo-3D maze with texture mapping and sprites. It uses GLFW to create a window ...
