Magical Players' Duel: Computer Vision Game Development Overview

Dive into the development of a computer vision-based game where players, acting as magicians in a factory, battle using spells. Learn about spell detection, operation detection, rendering effects, challenges, and problems faced during the project. Get insights into tools like Microsoft Kinect, OpenGL, nVidia CUDA, and Autodesk Maya used for this innovative game development. Discover the thrill of detecting basic interactions, spells, and rendering effects such as particle systems, shadows, and motion blur. Uncover the challenges of PhysX integration, effects implementation, and CUDA utilization on various graphics hardware. Explore the current project status, identify what is working well, what's missing, and the solutions and algorithms required to complete the game next week.
