GPU-based Visibility: Empirical Study

Academic SOLO project

Description

Implementation and evaluation of GPU-based visibility techniques against traditional ones. Built on C++ and OpenGL.
See the details in this post.

Lab project for the Fast Realistic Rendering course in MIRI, at UPC.

Results

See the interpretation in the referenced post.

Techniques evaluated

• Stop-and-wait using occlusion queries.
• Coherent hierarchical culling using occlusion queries.
• CPU-based viewfrustum culling (can be applied on top of both previous approaches).

Features

• Real-time navigation
• GUI to swap between techniques.
• Record and reproduce camera path.
