RXDK Demo – Visual Test App

A lightweight RXDK-based demo application for the original Xbox, focused on rendering visuals and testing input-driven UI logic without relying on the official Microsoft XDK.

This project is intended for experimentation, prototyping, and learning within the RXDK environment.

Features

• Custom rendering pipeline using xgraphics
• Button-mapped actions (no mouse / no virtual cursors)
• Designed for deterministic rendering (no dynamic allocations per frame)

RXDK Demos

• IntroScene - Opening title/logo sequence (new)
• ChromeScene - DOT3 bump-mapped sphere with per-frame normal animation and cubemap reflection
• PlasmaScene - Fullscreen animated plasma effect with swirling color patterns and camera drift
• BallScene - Physics demo with bouncing balls on a perspective grid floor, featuring squash/stretch deformation and multiple materials (rubber, chrome, glass, plasma) [New Look]
• RingScene - Animated ring/torus geometry effects
• GlassScene - Stained glass-inspired scene showing off CPU-based vertex shading and DOT3 PS shading.
• GalaxyScene - Procedural space scene with stars, nebulae, and dust particles with stats overlay
• CrystalScene - GPU-intensive cave grotto filled with luminous hex crystal formations, rendered with multi-pass DOT3 bump mapping and cubemap reflections.
• VURXDKScene - Large wireframe "RXDK" letters with music-reactive VU meter fills
• XScene - Xbox logo visualization
• CubeScene - Spinning cube with Matrix-style "RXDK" text rain on all 6 faces
• CubeEnvScene - A spinning cube with environment mapping and an Xbox-themed space background
• DripScene - Interactive water ripple simulation with multi-layer shading, rain mode, and realistic physics
• MazeScene - A cel-shaded Windows 95-like maze
• PostFXScene - A CRT signal corruption sequence: stable BIOS display progressively consumed by scanline interference, sync tears, chromatic aberration, barrel warp, and phosphor burn, collapsing to a dying horizontal line.
• Credits - Star Wars-style scrolling credits with perspective and color-coded shoutouts
• CityScene - Animated cityscape/skyline scene

Constraints / Design Notes

• No per-frame heap allocation
• Z-buffer disabled for predictable visuals
• Built to run cleanly on real hardware and emulators

Build Requirements

• RXDK toolchain
• Compatible C++ compiler for RXDK
• Standard RXDK libraries (xtl, xgraphics, xboxkrnl, libcmtd, xapilibd, d3d8d, d3dx8d, xapilib, d3d8, d3dx8, xgraphicsd, dsound)

Usage

• Build the project using RXDK
• Deploy the resulting XBE to an original Xbox or compatible emulator
• Navigate using a standard Xbox controller
