Real-time Rendering

News

• Here is a more complete framework for Lab2. It is missing an OBJ reader, but should have most of the other materials. The texture / sampler is over engineered. I was trying to find a way to prevent students from calling ActiveTexture.
• Homeworks 2 and 3 are finalized. These progress towards Lab2, which is also finalized.
• Lab1 extended until Sunday night.
• You can find my schedule on my Schedule page. My office hours (DL 683) are MF from 10:30-11:30, but feel free to set up a meeting time outside of these hours. Your grader's office hours are W 3:00-4:00 (DL 680), but again feel free to ask him for help as needed.

• Homework #1 is released for 2012. Due on Wednesday!
  • Note, the #version 150 core may need to be replaced with #version 130 on your machine.
  • Make sure you have up-to-date display device drivers on any personal machines.
  • The drivers on the CSE labs are old, except for the CL 112D machines.
• Lab1 is finalized.

Background

This course will look at the latest GPU technologies, algorithms and issues for real-time rendering on modern GPUs.

Description

This course will cover the latest architectures, alogorithms and techniques for interactive rendering (shading) of models. A focus will be on programmable GPU's and advanced texture mapping algorithms.

Level, Credits, Class Time Distribution, Prerequisites

Quarters Offered

• Winter

General Information, Exclusions, Cross-listings, etc.

• Graded A/E.

Intended Learning Outcomes

• Master a programmable shader language (e.g., GLSL, Cg, HLSL).
• Master using a high-level API for integrating the programmable shader language (e.g., OpenGL, DirectX, XNA).
• Be familiar with algorithms for creating shadows on the GPU.
• Be familiar with high-performance rendering.
• Be familiar with advanced texture mapping algorithms.
• Be exposed to non-photorealistic rendering.
• Be exposed to some of the latest implementations for real-time rendering.

Reading Assignments

Below are the reading assignments for the course:

• Week1:
  • Chapters 1-7 of the Orange book or the GLSL shader specification from OpenGL.org
• Week 2
  • Chapters 1-4 in the Real-Time Rendering textbook
• Week 3
  • The Direct3D 10 System, by David Blythe, Microsoft.
  • Chapters 5-6 in the Real-Time Rendering textbook
  • Troy Lawlor C++ class and tutorial for FBO's.
  • Song Ho Ahn's FBO tutorial (his diagram on Renderbuffers may be wrong).
• Week 4
  • Chapter 6 in the Real-Time Rendering textbook
  • Simulation of Wrinked Surfaces by Jim Blinn SIGGRAPH 1978
  • Chapter 8 in the Real-Time Rendering textbook
• Week 5
  • An Introductory Tour of Interactive Rendering by Eric Haines in IEEE CG&A (Jan/Feb 2006)
• Week 6
• Week 7
  • Chapter 9 in the Real-Time Rendering textbook
  • nVidia's Shadow resources
• Week 9
• Chapter 11 in the Real-Time Rendering textbook
• Exponential Shadow Maps (new formulation)

Development Environment

You will need access to at least a decent DirectX 10 class machine and Visual Studio 2008 or 2010 (Windows 7 or Vista is preferred). The machines in the graphics instructional lab in CL112D meet these criteria.

Representative Lab Assignments

Homework Ideas

Tentative Lab Assignments

• Lighting using programmable shaders
• Interactive 3D paint program with normal maps
• Interactive 3D paint program with multi-texture, multiple render targets, bump-mapping and geometry shaders
• Final Project - Student choice: NPR, Displacement mapping, Shadows, Volume Rendering, Shells and Fins, anything with the geometry shader,etc.

Lab Assignments Tools

• Here some vector and matrix classes if you do not already have one (Note the typedefs at the end - Vector3f).
• Here an example of creating a sphere using OpenGL's glu functions (note the source is in C#).
• The DevIL package is good one from reading images. It has some support for OpenGL, but I would suggest you do not use it.
