Brief Description
A pure browser JavaScript 3D viewer for classic Terminal Reality game track/level archives, including Monster Truck Madness, Monster Truck Madness 2, Terminal Velocity, Fury3/F-Zone, Hellbender and CART Precision Racing track data. Drop in a POD or ZIP file from local storage, or point it at a CORS-enabled URL, and the viewer decodes terrain, textures, objects, ground boxes, courses, trucks, water, backdrops, and CPR racetrack layers all client-side.

JSTrackViewer is based on JTraxx, which in turn is based on the original Traxx track editor for MTM1 & MTM2.

Furthermore, this viewer is still being worked on. Any feedback can be offered in the forum, here.

Limitations
Whenever you open a track from the website, you must use the full link like https://www.mtm2.com/tracks/exampletrack.zip.
Furthermore, make sure you note if you are on www.mtm2.com or mtm2.com. Due to internal security settings, the viewer will not open a truck if you mix and match the links. For example if you are on www.mtm2.com you have to use a truck link with www.mtm2.com, otherwise use mtm2.com etc.

- Rendering is inspection-focused; it does not emulate race physics, AI, audio playback, weapons, enemies, checkpoint, tunnels or game scripting.
- CPR racetrack wall rendering is supported but still approximate compared with the original renderer.
- TV/F3/HB tunnels are not supported.
- Animated models or textures are not supported.
- Ramps are not displayed.
- TopCrush models are not supported.
- Models or art not available on the POD file is not rendered.
