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:
- Install Visual Studio
