1 Pradeep Sen Class 21 – April 11, 2007 ECE 595 / CS 491 / CS 591 Real-Time Rendering & Graphics Hardware Pradeep Sen Advanced Graphics Lab Class 21 April 11, 2007 Pradeep Sen Class 21 – April 11, 2007 Announcements ± Project handout will be available online Pradeep Sen Class 21 – April 11, 2007 Last time ± Real-time geometry representations Pradeep Sen Class 21 – April 11, 2007 Today ± Procedural geometry for real-time applications Pradeep Sen Class 21 – April 11, 2007 Introduction to procedural geometry ± Traditional ways to represent geometry has several disadvantages: – Large storage requirements: every polygon needs to be stored – Lack of scalability: not so easy to change resolution in real-time – Geometry is difficult to modify in the application – Bandwidth bottleneck between CPU and GPU Pradeep Sen Class 21 – April 11, 2007 Introduction to procedural geometry ± Unlike standard geometry, procedural geometry is generated “on the fly” ± It has several advantages – Low storage overhead: typical tradeoff of computation for storage… store a small amount of information and reconstruct the rest – Scalable: The models can be generated at any target resolution – Reduce bandwidth bottleneck: less information to transmit from the CPU to GPU Pradeep Sen Class 21 – April 11, 2007 Different kinds of “procedural” graphics ± Vertex and fragment shaders ± Procedural animation (physics based) ± Procedural geometry (plants, clouds, terrain) Pradeep Sen Class 21 – April 11, 2007 Procedural animations ± Typically involve solving physics equations (mechanics) to determine the motion of objects in the environment Pradeep Sen Class 21 – April 11, 2007 L-Systems ± Developed by biologist Aristid Lindenmayer
