Triangle reduction or polygon reduction is a term you will often hear from us or anyone that’s involved in WebGL or the creation of video games. Our model arrived with full engine detail, interior of the plane, cockpit, landing gear, nuts and bolts and even wiring.
The key to reduction is knowing in advance what the user will see. In our demo’s case, we wanted to show how models are hollowed out and what items are removed. A flying position with wheels up, windows opaque, no ability to see within an engine allowed us to remove 1.2+ million triangles getting us to 240,037, below our target of 300,000. Keep this in mind as you prepare your model for export for use in WebGL. It may be easier to hide or remove them in your 3D application than having to have the WebGL developer remove them.
