  3. Introduction • Project Requirements • Applied Technologies • Current Results • Future Works • Program Demo • References Capstone Project Fall 2009 - Team 6 Table of Contents

  4. Capstone Project Fall 2009 - Team 6 PROJECT Introduction Solar Power Thermal Plant

  5. Develop a photo-realistic 3D simulation of a solar power plant Render shadows of heliostats and towers Viewable from any perspectives Accurately model the motion of the sun and heliostats Update simulation faster than in real-time Capstone Project Fall 2009 - Team 6 RequirementS

  6. The sunlight to a heliostat is blocked by front heliostats. Capstone Project Fall 2009 - Team 6 shading

  7. OpenGL • Open Graphics Library • Support rendering 3D simulation • CUDA • General purpose parallel computing architecture developed by NVIDIA • Improve program performance Capstone Project Fall 2009 - Team 6 Applied Technologies

  8. Mathematical mechanism • Specifies all the vertices of the shadow area • Requires much of GPU computations • Stencil Shadow Volume • Not specifies the vertices of the shadow area • Requires less computations on GPU • Making use of OpenGL Capstone Project Fall 2009 - Team 6 Applied Mechanisms for shading

  9. Capstone Project Fall 2009 - Team 6 SIMPLE PROGRAM FLOW Heliostats' center coordinate Render heliostats (4 vertices) Calculate vertices Thermal Plant Configuration • Tower location • Time and date • Heliostat’s width and height • … CUDA OPENGL Render shadows Shadow Volume

  10. Capstone Project Fall 2009 - Team 6 OpenGL Thermal Plant Configuration Heliostat 1 V1 V2 V3 V4 • Tower location • Time and date • Heliostat’s width and height • … Heliostat 2 V1 V2 V3 V4 Heliostat 3 Heliostats’ center coordinate OPENGL V1 V2 V3 V4 …. …. Heliostat n V1 V2 V3 V4

  11. Capstone Project Fall 2009 - Team 6 CUDA Thermal Plant Configuration Heliostat 1 V1 V2 V3 V4 Thread 1 • Tower location • Time and date • Heliostat’s width and height • … Heliostat 2 V1 V2 V3 V4 Thread 2 Heliostat 3 OPENGL V1 V2 V3 V4 Heliostats’ center coordinate Thread 3 …. …. Heliostat n V1 V2 V3 V4 Thread n CUDA
