Simplygon SDK LOD生成工具

快速实现模型LOD简化面生成的开发包，可以集成到任何编辑器中，这个版本已破解. The Simplygon SDK provides powerful methods to optimize 3d assets, which can easily be im- plemented 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 dierent 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 remeshin 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.
