FastTerminal for Java — Real-Time 3D Rotating Wireframe Cube (120 FPS)

This video showcases a high-performance demonstration of rendering real-time, interactive 3D vector graphics inside the standard command prompt / system terminal at a locked 120 FPS!

Built entirely in Java using FastTerminal's zero-dependency virtual cell buffers, the engine projects and rotates a 3D wireframe cube along three axes (X, Y, and Z) against an active, drifting starfield backdrop.

Key Technical Highlights:
- Locked 120 FPS Refresh Rate: Super-smooth, double-buffered rendering with zero input lag.
- 3D Tumbling Matrix Rotations: Real-time pitch, yaw, and roll calculations applied to the cube's vertices.
- Perspective Depth Mapping: Dynamic scaling based on Z-depth distance, corrected by a 2.1 horizontal factor to ensure the cube looks perfectly square within rectangular console cells.
- Bresenham's Line Blitting: A high-performance custom line drawing algorithm blitting solid block characters (█) directly to the scene buffer.
- Twinkling Starfield Backdrop: 60 stars drifting at variable speeds over an obsidian black (0x05070A) canvas.
- Dynamic Color Cycling: Solid glowing edges that shift through rich neon gradients in real-time.
- Zero Dependencies & Full Console Safety: Complete isolation from bloated third-party terminal wrappers, featuring a robust JVM shutdown hook to cleanly restore your console.
