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]
