Subject and aim

The course teaches fundamental real-time rendering techniques like tessellation, deferred shading, and screen-space effects, and discusses bleeding-edge topics like real-time global illumination, physically-based rendering, and optimizing GPU performance.

The goal is to give you a firm understanding of all constituents of a modern real-time rendering engine!

Communication

The whole communication runs over the TUWEL-Page. Information regarding the exercises are also available on TUWEL.

Please register for the course on the TISS-Page!

Assignments

The lecture is accompanied by assignments that cover advanced but fundamental techniques of real-time rendering. Assignments are programming exercises in frameworks based on (modern) C++ and OpenGL or Vulkan. Ready-to-use versions of the frameworks and the assignments will be provided for Visual Studio 2019.

All assignments will be available on TUWEL at the dates stated above.

Assignment #1 Normal Mapping
Tangent Space, Blinn-Phong Shading, Physically-based Shading (bonus)
10 points (+10 bonus points)
Assignment #2 Hardware Tessellation
PN-Triangles, Adaptive Tessellation, Displacement Mapping
30 points (+20 bonus points)
Assignment #3 Deferred Shading and Synchronization
Vulkan Synchronization, Deferred Shading, MSAA
30 points (+14 bonus points)
Assignment #4 Screen-Space Effects
Screen-Space Ambient Occlusion, HDR Rendering + Tone Mapping, Screen-Space Reflections, Temporal Anti-Aliasing, Real-Time Ray Tracing
30 points (+22 bonus points)

Every assignment will feature a set of basic tasks and bonus tasks. Solving bonus tasks will allow you to earn more than 100% of the regular point maximum for this assignment. With this, you may compensate lower percentages in other assignments.

Grading

Final grading is based on the points you acquire for the 4 assignments, according to the following scheme, AND on your participation in the "solution presentation and group discussion" events (compulsory attendance!).
5 00 - 49 points
4 50 - 62 points
3 63 - 74 points
2 75 - 87 points
1 88+ points
Participating in the "solution presentation and group discussion" events is mandatory. In order to get a positive grade (i.e. 4 or better), you have to present your overall solution for an assignment, your approach to a task, or some implementation-specifics of your submission at least once.

To be perfectly clear on this: You will not get a positive grade if you do not present in one of those three events, even if you have 50+ points.

Your participation and constructive contribution to the group discussions will influence your final grade. A positive, constructive performance can improve your final grade while a lack thereof can impair your final grade. These events replace individual submission talks, so use them to show us that you are the author of your submitted solutions and let's learn from each other in profound group discussions.
