Screen-Space Normal Distribution Function Caching for Consistent Multi-Resolution Rendering of Large Particle Data
This repository contains a GPU based implementation of the paper: "Screen-Space Normal Distribution Function Caching for Consistent Multi-Resolution Rendering of Large Particle Data" The paper is implemented in C++, OpenGL and GLSL in Visual Studio on a Windows machine.
This code was tested with:
- Visual Studio 2015
- OpenGL 4.5
- Windows OS
- Clone repository into a local destination on your machine.
- Place any data set you wish to load in the folder 'data', data set must be in '.mmpld' format. The projects loads the 'laserAblation' data set by default, available in the 'data' folder.
- Open the solution 'PointImposters/NdfImposters/NdfImposters.sln'.
- Set the project 'NdfImposterLibraryTests' as the start-up project.
- Build the solution.
- Run the project.
