3D on Apple II

Embark on a nostalgic coding adventure with this 46-minute video that showcases an attempt to build a 3D graphics engine using AppleSoft BASIC on a restored Apple II+ computer. Learn how to create a spinning cube through step-by-step instructions, covering topics such as double-buffered animation, high-resolution graphics initialization, line animation, screen switching, rotation techniques, matrix multiplication, and point connection. Explore the challenges of working with vintage hardware and software while gaining insights into fundamental 3D graphics concepts. Discover optimization techniques and consider ways to enhance the project further, such as adding perspective projection. Perfect for retro computing enthusiasts and those interested in the foundations of computer graphics programming.

The future of computer graphics!
