FastPoints: A State-of-the-Art Point Cloud Renderer for Unity

TL;DR

FastPoints is a new point cloud renderer for Unity that enables real-time rendering of large clouds with minimal setup, using an online octree construction for efficient out-of-core data handling.

Contribution

It introduces FastPoints, a real-time point cloud renderer supporting large clouds with online octree construction and seamless Unity integration.

Findings

Supports standard point cloud formats with drag-and-drop

Constructs an out-of-core data structure without preprocessing

Maintains Unity editor interactivity during rendering

Abstract

In this paper, we introduce FastPoints, a state-of-the-art point cloud renderer for the Unity game development platform. Our program supports standard unprocessed point cloud formats with non-programmatic, drag-and-drop support, and creates an out-of-core data structure for large clouds without requiring an explicit preprocessing step; instead, the software renders a decimated point cloud immediately and constructs a shallow octree online, during which time the Unity editor remains fully interactive.
