Project Title

A lightweight 3D viewer can render massive mesh surface model without LOD popping and mesh cracks.

Description

The viewer is developed based on C++, OpenGL, GLSL. The overview is as follows (The colorization of the different LODs):

• HLOD construction
• Real-time rendering

Getting Started

Dependencies

• System: Linux

• Libraray: GLFW, GLAD, OpenGL, Pthread,

  Mesh simplification is based on MeshOptimizer

Installing

• In-core mode

  make

• out-of-core mode (TODO)

Executing program

• In-core mode

  ./bin/viewer model_filepath

How to move object in 3D Viewer

• Zoom: Middle Mouse Button / Ctrl + Left Mouse Button
• Rotate Object: Left Mouse Button
• Translate Object: Shift + Left Mouse Button

Whole process demo

• The whole process of multi-resolution model construction (13 seconds) and real-time rendering of David (56M triangles) on a desktop without discrete GPU. Video
