How to View Diplodocus in 3D
Diplodocus 3D Viewer runs a long-tailed Late Jurassic sauropod - the D. carnegii reference scale - in your browser. Drag to rotate, scroll or pinch to zoom, toggle a 1.8 m person for scale, and click the head, neck, body, a leg, or the tail for a fossil-sourced fact.
Open the Diplodocus page and take the camera
Open the Diplodocus 3D Viewer and wait for the facts panel to fill. When the status line says you can drag, orbit the Diplodocus with the pointer and zoom with the scroll wheel or a two-finger pinch. Fullscreen expands the wrapper so the controls stay visible beside the scene.
Use the four Diplodocus controls under the canvas
Under the Diplodocus canvas, four controls handle view and scale:
- Fullscreen - fills the display while keeping the buttons visible
- Stop rotation / Auto-rotate - freezes or resumes auto-spin
- Idle motion - adds subtle breathing and sway; tap again for Stand still
- Size vs human - shows a 1.8 m person at the honest length ratio used by the viewer (about 25 m; published D. carnegii range about 24-26 m)
Read the Diplodocus facts panel and click body parts
The Diplodocus facts panel lists length about 25 m (published D. carnegii range about 24-26 m), weight about 13.5 tonnes (published range about 12-14.8 tonnes), the 152-149 Mya Late Jurassic (Kimmeridgian) window, herbivore diet with small forward-pointing peg teeth suited to stripping leaves, and discovery - Othniel Charles Marsh named the genus in 1878; John Bell Hatcher described D. carnegii in 1901 from specimen CM 84 found near Sheep Creek, Wyoming in 1899. The model uses the shared sauropod builder without tallForelimbs, so the neck sits lower and more level than Brachiosaurus - matching Diplodocus as the longest-not-tallest sauropod in this series. The whip-like tail (about 80 caudal vertebrae) may have served defense or signaling - stated as a debated hypothesis, not settled fact. A short click - not a drag - on the head, neck, body, a leg, or the tail surfaces a short fossil fact; click empty space to return to the species sheet. Skin and color are an artistic reconstruction, not a fossil-accurate skeleton. The model is procedural sauropod with no free-licensed Diplodocus glTF re-hosted yet.
What the Diplodocus how-to guide is not
The Diplodocus how-to guide is a controls walkthrough for the in-browser viewer only - it does not place the model in your room (no AR), does not claim soft-tissue or color accuracy, does not invent one precise length or weight beyond the cited D. carnegii range, does not treat the whip-tail defense idea as settled science, does not invent a glTF credit, and does not invent game score or win states.
