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.

ROAM Simplistic Implementation By Bryan Turner brturn@bellsouth.net January, 2000 Project file for MS Visual C++ 6.0. Requires GLUT DLL (www.opengl.org) Adjust program constants in Landscape.h and Utility.cpp. MAPS: Default map is read from HeghtXXX.raw where XXX is the MAP_SIZE (as defined in Landscape.h). If this map is not found, the program attempts to open "Map.ved", a Tread Marks map file. Tread Marks maps will only work for MAP_SIZE == 1024. Also, the MULT_SCALE to view Tread Marks maps correctly is "0.25f". (www.TreadMarks.com) CONTROLS: MOUSE - Hold Left Mouse Button to Rotate View Angle Q - Change Rendering Mode (Wireframe, Lit, Fill, Texture) O - Change View Mode (Observe, Follow, Drive, Fly) W/S - Move forward/back A/D - Rotate left/right (in Observe Mode only) F - Stop Animation R - Toggle Frustum Drawing 0/9 - More/Less Triangles per frame 1/2 - Adjust FOV
