View-dependent progressive meshes implementations

This project includes implementations of View-dependent progressive meshes. http://research.microsoft.com/en-us/um/people/hoppe/proj/vdrpm

Libraries: vdpm: Core runtime refinement library. Features includes

• Geomorph with custom enhancement to reduce popping effect.
• Refinement criteria:
  • View frustum
  • Surface orientation
  • Screen-space geometric error
• Regulation
• Amortization
• Runtime triangle strips generation
• OpenGL VBO & IBO renderer
• Custom number of vertex attributes (Normal/Color/TexCoord)

Source codes are at share/vdpm. Configuration is at share/vdpm/include/vdpm/Config.h.

osgVdpm: OpenSceneGraph wrapper. Features includes

• Encapsulates SRMesh as osgDrawable
• UserStats to show VDPM related parameters
• Serializer to convert general model to VDPM format.
• Multiple viewport with multiple SRMeshes are possible.

Source codes are at share/osgvdpm.

MixKit: Modified from QSlim to support VDPM format conversion. http://mgarland.org/software/qslim.html

Features includes

• Algorithm: Simplifying Surfaces with Color and Texture using Quadric Error Metrics
• Refinement criteria calculation:
  • Cone-of-normals angle
  • Uniform error
  • Directional error

Source codes are at share/mixkit.

Program: vdpmview: Simple UI to display .vdpm model. WIN32 GUI program. Source codes are at project/vdpmview.

vdpmslim: Modified from QSlim to support VDPM format conversion. Console program. Source codes are at project/vdpmslim.

osgvdpmstaticviewer/osgvdpmcompositeviewer: Modified from osgstaticviewer/osgcompositeviewer to display .vdpm or osgt/osgb format of vdpm files. Source codes are at project/openscenegraphvdpm.

osgvdpmconv: Modified from osgconv to convert general models to osgt/osgb format of vdpm files. Source codes are at project/osgvdpmconv.

Platform: Built and tested on windows platform only.

How to build:

1. Install Visual Studio
2. Install CMake
3. mkdir /build
4. In CMake GUI:
   • Where is the source code: --> [Root directory of this project]
   • Where to build the binaries: --> [Root directory of this project]/build/[program name]
5. Press [Configure] & [Generate], the solution files will be generated at [Root directory of this project]/build/[program name]
