Grain of SALT, the Geometry Simplification At Load Time library

Introduction

GSalt is a library tobe used to simplifiy geometry at load time.

That means:

1. Simplify geometry: remove vertex/triangle from a model, while still trying to maintain visual aspect
2. A load time: because it may takes time, so don't expect realtime "LOD" algorythms (LOD = Level Of Detail)

The library use the algorithm by Mickael Garland "Surface simplification using quadric metrics"

Build

Simply

cmake
make
sudo make install

You'll need a C++ compiler for it.

Use

v0.1 only have single texture and no batch feed of vertex/triangle.

You can find an example in the examples folder. The SimpleViewer can show "obj" mesh and you optionnaly can reduce the triangles count by command line.
