CGV Midterm Master Project Presentations

You are cordially invited to attend the midterm master project presentations on Friday, 19 February starting 14:30. The session will be on Zoom (meeting detail available on request).

The session on 19 February features the three speakers listed below and will take about 1.5 hours.

Speaker 1: Nejc Maček

Title: Real-time relighting of human faces with a low-cost setup

Abstract: Relighting – a process defined as changing the appearance of a subject in an image under novel illumination conditions – often requires specialized equipment to produce believable results. We propose a method to capture an abstract relighting model with a low-cost setup using a smartphone camera. This model is used to perform relighting in real-time on a commodity computer.

Speaker 2: Zhoufan Jia

Title: Fast approximation of the inverse reflector problem

Abstract: Suppose we have a target radiance distribution, a light source and a plane for receiving light. How do we design a reflector that can give a similar result as the target radiance distribution? This is a problem of high interest for light designer and related industry, such as lamp manufactures. The inverse reflector problem can be summarized as a high-dimensional global optimization problem. Some existing algorithms are either not fully compatible with parallel acceleration, or with a too narrow application scope (can only deal with the far-field problem). We proposed a method for generating a fast approximation of the reflector’s inverse design, which can also serve as the initial guess for the a finer optimization.

Speaker 3: Matthias Tavasszy

Title: Real-Time Global Illumination using BRSM and Light Cuts

Abstract: Global illumination is light that bounces through an environment multiple times before it ends up at an observer, which is very computationally expensive to simulate. In order to approximate this effect in real time this work combines two previous works,  Bidirectional Reflective Shadow Maps and Light Cuts in order to quickly generate, organize and sample Virtual Light Points for gathering second-bounce illumination at a given location. The program is implemented in Vulkan using RTX ray tracing for occlusion checks.
