The ESR 01 PhD position within PRIME is about developing efficient light transport simulation algorithms for volumetric materials used in 3D printing, and about the inclusion of fluorescence in modern rendering technology. The optical effect of fluorescence is currently neglected in most rendering software, but it plays a significant role in the appearance of certain materials. The research undertaken by this ESR will be both fundamental research about inclusion of fluorescence in modern rendering technology, as well as work with appearance measurement, and the trialling of such rendering capabilities in actual industrial workflows.

The ESR 02 PhD position within PRIME is all about representing wooden materials for virtual objects. The appearance of wood is a complex product of sub-surface scattering and oriented fibers. For reliable, accurate renderings a more sophisticated solution is necessary than approximating textures. The candidate should develop a new model for wood appearance that allows for accurate predictions in the context of wood-based fabrication together with an accompanying capture technique to measure parameters off real samples.

The ESR 03 PhD position within PRIME is about developing advanced light transport simulation specifically targeted at Virtual Reality. Light transport algorithms have become increasingly sophisticated and able to capture complex lighting phenomena. Furthermore, recent developments in graphics card technology (GPUs) have made it feasible to simulate light transport at interactive rates. However, this is not yet feasible in Virtual Reality headsets where the frame rate is high and two images (stereo) are rendered simultaneously. Basic algorithms such as path tracing do not scale well to VR headsets as the algorithm fails to exploit coherence and the noise in path tracing makes the VR experience suboptimal. The goal of this task is to develop novel light transport algorithms that can exploit the coherence in VR and also eliminate the noise, so that interactive stereo rendering becomes useful.
Pay is standardised by the EU, and allows for comfortable living as a student by local standards. Living allowance is approximately 4400 EUR/month with Family allowance and Mobility allowance to cover cost of moving. Taxes apply, which would normally be in the range 37-40%.

Luxion is a research driven company. At its core Luxion brings innovations in computer graphics and related fields to users in industrial design, marketing and engineering through a fast and easy to use software application. We are a leading developer of advanced 3D rendering, animation and lighting technology with expert knowledge in areas related to daylighting (atmospheric scattering), light scattering by materials (BRDF and BSSRDF models), light transport algorithms such as photon mapping, and real-time rendering technology. KeyShot is the first real-time ray tracing application that uses a physically correct render engine based on scientific research in the areas of scientifically accurate material representation and global illumination. Luxion ApS office is located in Aarhus, Denmark. The candidate will benefit from Luxion’s expertise with VR including having access to state of the art VR equipment. In addition, Luxion under the guidance of Dr. Mosegaard has developed a VR application based on classic rasterization techniques that provide guidance for the goals of VR in general. This project will benefit from Dr. Mosegaard, who has a PhD in realtime rendering and more than ten years of experience in VR and real-time rendering as well as Dr. Jensen, who has been working on advanced light transport algorithms for more than 30 years. The academic supervisor will be Dr. Frisvad at DTU, Copenhagen. As such the candidate should expect to also spend time in Copenhagen and travel back and forth accordingly.
The ESR 04 PhD position within PRIME is about developing robust error bounds for light transport algorithms. Sophisticated light transport algorithms are used throughout product design, architectural rendering, and movie production. Often the quality of the final image depends simply on the presence of noise in the image. With the increasing use of deep learning for denoising there is less understanding of the actual error in the final image. Simple algorithms such as path tracing support stochastic error bounds by analysing the variance in the image, but bidirectional methods such as photon mapping and path tracing in combination do not have a metric developed that enables computing error bounds. The goal of this task is to develop error bounds for state of the art light transport algorithms and if necessary modify these algorithms to support robust error bounds. Having error bounds will facilitate accurate predictions of lighting in architecture and product design. Understanding the error properties of advanced light transport algorithms will also help to guide future refinements of these algorithms for the purpose of faster convergence.

The ESR 05 PhD position within PRIME is about synthesising training data for machine learning. Computer vision, for instance when used for autonomous driving, relies heavily on machine learning. Large sets of training data are required to effectively “teach” the computer how to handle complex real-world scenarios. Some critical real-world events that a machine learning method needs to handle well are either too rare (e.g., specific weather conditions) or too dangerous (e.g., a toddler falling in front of a car) to gather in the real world. The research undertaken by this ESR will identify what level of physical accuracy is required to successfully train machine learning approaches from synthetic data. Further, advanced algorithms and high-performance implementations will be investigated, to achieve sufficiently large data sets.

We are doing research in computer graphics, high performance rendering, and their applications in artificial intelligence. Both our research group and our university are highly international.
The ESR 06 PhD position within PRIME is about simulating non-visible light. Light transport simulation via Monte Carlo methods is seeing an increased use in, e.g., optics to simulate non-visible wavelengths like infrared or ultraviolet. They are also used in telecommunications and electrical engineering to simulate, e.g, radar. In recent years, however, the majority of improvements to light transport algorithms were made mostly with visible light in mind. Effects such as diffraction, which become increasingly important for longer wavelengths, have not received much attention. The research undertaken by this ESR tackles the efficient simulation of such effects.

The visual appearance of real-world materials does not remain static over time, as the physical objects are subject to environmental effects. Faithfully predicting such changes has a wide range of applications. In industrial designs, certain surfaces attract fingerprints right away, others scratch easily, colours fade through light exposure, and surfaces attract dirt or dust. In architectural applications, the influence of weather and seasons changes materials over time, even to the extent of erosion and build-up of matter. In computer graphics, realistic wear of surfaces is often what separates a “photo-real” look from an unrealistically clean “computer graphics” appearance.
Based on the state of the art in both machine learning and physical modelling, the ESR 07 PhD candidate within PRIME will be developing phenomenological models of material ageing, to plausibly age objects across a wide range of materials and environments, including previously unobserved materials, achieving plausible, photo-realistic renditions of their weathered and worn surface characteristics. These models will be driven by data from physical simulations and from photographs under controlled conditions and time series. The work will be supported through secondments and collaboration with industry leaders in surface appearance authoring.

The department is located in central London, close to the British Museum and British Library.
The ESR 08 PhD position within PRIME is about developing controllable GANs to produce realistic content in the form of both geometry and associated material specifications. For example, in the context of indoor room design, an essential requirement is to have a ‘realist’ layout so that the users can use the provided visualizations to make design decisions. Realism in such a context refers to both aspects relating to semantic (e.g., object types, their relative layout, envisioned usage and affordability of the space) and photo-realistic (e.g., object color, assigned material, ‘natural’ illumination) details. The goal of this task is to develop a data-driven machine learning approach to capture and subsequently jointly perform geometry and associated material generation. While we plan to use procedural methods to create geometric content – both in terms of object selection and their placement – by utilizing a database of high-quality object collections and material assignment based on examples provided by professional designers. ESR 08 will focus on developing controllable GANs that help with high quality 3D assets both in terms of scene composition as well as functionality of the environment.

The ESR 09 PhD position within PRIME is about predictive rendering of powder materials (or, more generally, particulate materials). The task of ESR 09 will be to learn and model the distribution of particles in surfaces of particulate materials and estimate the reflectance properties of such surfaces based on light scattering by particles. This is an interesting research challenge because particles are currently considered independent scatterers in a volume, but in this project we will explore the surface reflectance properties of powder materials made of tightly packed particles. Our objective is appearance models that provide predictive rendering of particulate materials with relevance in 3D printing or other production. Parameters of the appearance models should be linked to relevant print/production parameters, so that the models are useful for rendering synthetic datasets for training neural networks to perform quality assurance tasks.

The ESR 10 PhD position within PRIME is about the global formulation of the appearance of an object in terms of a macroscopic scattering function (the BSSRDF), and the role that such functions can play in the specification of material appearance. There is currently no standardized way of specifying reflectance properties that include subsurface scattering. The BSSRDF is a general reflectance function including both in-surface and subsurface scattering of light. It is thus a good candidate for specifying product appearance, but it is also a function of high dimensionality, which makes it hard to find practical representations for the BSSRDF. Existing BSSRDF models are typically either impractical or limited in predictive quality. In this project, the ESR will explore the predictive quality of existing BSSRDF models and develop new BSSRDF models for practical, predictive appearance specification. This research includes development of practical techniques for rendering with the BSSRDF, and the models should be informed by the microgeometry of the materials that they can specify the appearance of.

Visual appearance helps us recognise real-world objects and convey information about them, such as whether an object is wet or dry, a surface is hard or soft, etc. However, simulating and editing such visual appearance is a challenging goal involving fields like computer science, applied mathematics, or physics. The ESR 14 PhD candidate within PRIME will develop novel ways to model and edit material appearance in a manner that is intuitive and correlates well with human perception. In particular, the candidate will develop a descriptive semantic space for material appearance, which will bridge the current gap between low-level appearance optical properties, and high-level, intuitive traits.
