Home < GPU accelerated FEM for simulation and segmentation
Key Investigators
- Megumi Nakao and Nobuhiko Hata
Objective
We are developing a fast FEM-based mesh deformation library for interactive simulation and segmentation. The goal in this project week is summarized as
- integrate linear FEM-based deformation algo into the slicer
- perform deformation on specific data
- implement GPU-based acceleration for real-time deformation
Approach, Plan
- integrate a liner FEM solver(original C++ source) into the 3D slicer framework.
- make tetrahedral meshes from medical images and set up physical conditions. Other mesh formats, points and surface models will be probablly accepted.
- evaluate some deformation results qualitatively and improve the simulation.
- try GPU-based acceleration by modifying the linear equation solver using CUBLAS library.
Progress
I will work in Wednesday, Thursday afternoon and Friday.
