  1. CUDA Based LDI Generation Rui Hu, Xitong Liu

  2. Outline • Algorithm Implementation • Correctness Validation • Performance Evaluation • CUDA Programming Tricks • Conclusion

  3. Section I : Algorithm Implementation

  4. Algorithm Overview

  5. Rasterization Thread

  6. Depth Sorting Thread Each thread processes one fragment __shared__ float sortBufS[MaxFragPerThread][LDImaximumLayer];

  7. Depth Sorting Thread

  8. Section II : Correctness Validation

  9. Correctness Validation • Compare our results of Simple Cube with the result generated by SOFA Framework • Both results match

  10. Section III : Performance Evaluation

  11. Section IV : CDUA Programming Tricks

  12. CUDA Programming Tricks • Register variable reuse – Save register space • Check CUDA runtime errors • cutilCheckMsg • cudaGetLastError • cutilCheckError • cutilSafeCall • Select the appropriate compiling options

  13. Section V : Conclusion
