Dimensionality reduction algorithms transform high-dimensional datasets with many attributes per observation into lower-dimensional representations (called embeddings) such that the structure of the dataset is maintained as well as possible. In this research, the use of Virtual Reality (VR) to analyse these embeddings has been evaluated and...

Lighting design is a computational expensive task, commonly done using Computer-aided design (CAD) software in a virtual scene. The designer places and tunes the virtual light sources and, yet the virtual environment is ideal for physically correct light tracing, the costly simulation might not provide the desired impression in the real scene....

Quantifying the anthropogenic impacts such as reservoir characterization is a big challenge in the field of water management. In this work, a computer graphics based geometric approach is presented which can predict the underlying topology of large-scale reservoirs. The proposed algorithm uses freely available, satellite based landscape data of...

This study focuses on the question how the bandwidth utilization of a high-quality video-stream from the Exposure Rendering framework can be minimized. Exposure Render uses a Monte-Carlo based rendering system to render volumetric data. The earliest estimation of lighting show high degrees of noise, leading to grainy images before...

Image colourization is the task of providing colour to grayscale images or videos. Image colourization can be valuable to the entertainment industry and of cultural interest. Current methods colourize images by either providing an interface for easier colourization by a person or by using an automatic method which nowadays are often driven by a...

Catoptric anamorphosis is an image which seems to be distorted, but looks normal when observed from a specific point of view and indirectly via a reflective object. While some methods already exist that can create such images, they are limited in the amount of differently shaped reflective objects they support or they require you to obtain a 3D...

In recent years, there has been a widespread increase in the adoption of virtual reality and 3d displays which require many images as input, e.g. head mounted displays or lightfield displays. Real-time rendered imagery for such displays is commonly computed using brute-force rendering pipelines based on forward(+) or deferred rendering pipelines...

Volumetric light scattering caused by participating media has been and still is a complicated, but visually pleasing lighting effect that increases the sense of realism of digital scenes tremendously. Various solutions to rendering these effects in real-time exist, basing themselves upon the single scattering approximation. Transparency is...

Vector-based graphics are not directly compatible with the raster-based structure of dedicated graphics hardware. They suffer from a locality problem where, in order to check if a specific display pixel lies inside or outside the shape, the entire shape needs to be taken into account. This negates the advantage that the graphics pipeline’s...

Photographers suffer from many challenging problems when separating and compositing images, such as the color camouflage and unpleasant color bleeding artifacts. To tackle these issues, we present a solution to fore- and background segmentation for images taken from multiple cameras, which introduce the parallax that leads to the foreground...

Games such as Skyrim use a narrative world, which is a game world that is used to tell stories. Creating narrative worlds is a time-consuming process because of the collaboration of writers, 3D artists and game designers, the story adjusting the world over time and the requirement for diverse and interesting environments. This thesis focuses on...

Path tracing has been successfully utilized in modern animated films to produce photorealistic images. However, with path tracing being a Monte Carlo method, a large amount of light paths must be sampled to reduce image noise to acceptable levels. Although a wide variety of acceleration and importance sampling techniques have been developed to...

The acoustics of a space contribute much to the perceived size and atmosphere of the environment. Modeling these acoustics in virtual environments can make a big improvement to the immersion of the player. There are very accurate models that can reproduce realistic acoustics in virtual spaces, but these are computationally very expensive....

We present a fast and accurate general relativity raytracing algorithm to visualise the distortion of space around a fast spinning Kerr black hole, as seen from a position nearby. Different parallel numerical ray integration methods were tested to solve this problem. An adaptive grid of rays, stored in efficient data structures with fast access,...

Energiepaleis, a company that realizes sustainable home renovations, requested an application that uses augmented reality to show their customers beforehand, what certain sustainable devices would look like in their homes after renovations. A marker is placed on the spot where the device needs to stand and then the application will show the...

Inaccurate and slow positional tracking are fundamental problems of low-cost VR solutions. These factors can induce motion sickness and therefore significantly deteriorate the user experience. There are already a variety of solutions available to track the position of a VR HMD, some of which can be made robust and
low-latency by inexpensive...

During the Bachelor End Project we have been tasked with developing a web portal for the Exposure Render. The Exposure Render is able to interactively visualize volumetric data to photo realistic images. This means that the web portal would allow users to view a visualization of their medical data.
The requirements of the web portal have...
