The PowerPlant Model: 13 MILLION TRIANGLES

Introduction

The Power Plant Model is a complete model of an actual coal fired power plant. It is now being released for non-commercial use. The model consists of 12,748,510 triangles in 1185 .ply files, and is available in one large download or in smaller sections for those not needing the entire model.  The Walkthru Group  at UNC Chapel Hill has used the model extensively for its research in Interactive Rendering, Visibility Culling, Simplification, Texture and Image-Based Techniques, Collision Detection, Virtual Environments, and other research areas.
