CSE 190 - GPU Programming UCSD class Winter 2014

GPU Programming
With the new console generation and the advances in PC hardware, compute support is becoming more important in games. The new course in 2014 will therefore start with compute and we will spend about a 1/3 of the whole course talking about how it is used on next-gen consoles and in next-gen games. We will also look into several case studies and discuss the feasibility to "re-factor" existing game algorithms so that they run in compute. An emphasis is put here on effects that are traditionally used for post-processing effects.

The remaining 2 / 3 of the course will focus on the DirectX 11.2 graphics API and how it is used in games to create a rendering engine for a next-gen game. We will cover most of the fundamental concepts like the HLSL language, renderer design, lighting in games, how to generate shadows and we also discuss how transparency can be mimicked with techniques other than alpha blending.
The course will end with a survey of different real-time Global Illumination algorithms that are used in different types of games.

Will it be possible to post your course lecture slides online somewhere so that others can make use of this awesome course?

Andrew said...

Yeah, anything like that would be hugely welcome as I'm from Europe

Jordan Ellis said...

I am wondering this as well, is there anywhere the classes lecture notes/slides are posted?
