Abstract: The key to real-time rendering of large-scale surfaces is to locally adept surface geometric complexity to changing view parameters. The Level-of-Detail Algorithm ROAM employs top-down recursive approach in rendering the Binary Triangle Trees (BTT) and calculates the coordinates of the triangles (to be rendered) on the fly. Hence, to overcome both the top-down recursive rendering approach and runtime coordinate calculation of the BTT, this paper presents the concept of Binary Coordinate Trees (BCT). Frame-to-frame coherence and Linear rendering of the Connected Leaf List (LRCLL) has also been efficiently handled using BCT.
