Live voyage through a collection of low-level and advanced GPU programming topics with a focus on unconventional thinking. Starting with an interactive look at driving the CPU from the GPU: showing a GL based pipeline where shaders can write to a command buffer which the CPU executes, enabling GPU driven reconfiguration of resources and rendering pipeline. Exploring methods to use this kind of rapid development tool for manual run-time profile guided optimization. Continuing with a visual exploration of advanced filtering techniques for real-time ray based rendering, and methods to enable 1080p ray-march at 120Hz and beyond.
