Introduction

Simplygon Overview

The Simplygon API provides powerful methods to optimize 3d assets, which can easily be implemented and integrated into your 3d asset pipeline. At the very core, the optimization can be divided into two parts: Geometric optimization and 2d-material optimization.

There are two different approaches that Simplygon uses to optimize the geometric data. Through reduction, geometric data is reduced using re-linking of triangles and vertex removal, and through remeshing, where the geometries are replaced by a lightweight proxy geometry that resembles the original.

The material casting is a post-process of both the reduction and remeshing processing, where the caller application can use the mapping image data to cast material and texture data from the original onto the processed geometry. This can either be used to increase the details of the data, using normalmaps, or greatly reduce the amount of data through baking together a large number of texturemaps into a single one.

Known Issues

There is a large address aware issue on Windows 7 x64. When executing a x86 hosting process with the LARGEADDRESSAWARE option the Simplygon API initialization fails. The solution to the problem is a windows Hotfix by Microsoft which can be found at http://support.microsoft.com/kb/2588507.
