Using voxel hierarchies as a generic 3D scene representation makes ray marching, antialiasing, and LOD easy. The drawback is the huge amount of memory required to store voxels, even with empty space compression. Still, GigaVoxels showed that by using a ray-guided cache to produce and store only visible voxels bricks on demand, it is possible to wal...
Rendering realistic virtual environments requires intense computation that will always scale to the generational expectations of what users consider high-quality. With the renewed interest in Virtual Reality and display technologies becoming more proficient, computational requirements will increase even further. However, human perception is limited...
VR devices have recently been actively promoted as tools for knowledge workers and prior work has demonstrated that VR can support some knowledge worker tasks. However, only a few studies have explored the effects of prolonged use of VR such as a study observing 16 participants working in VR and a physical environment for one work-week each and rep...
Collision detection is a fundamental computational problem in various domains, such as robotics, computational physics, and computer graphics. In general, collision detection is tackled as a computational geometry problem, with the so-called Gilbert, Johnson, and Keerthi (GJK) algorithm being the most adopted solution nowadays. While introduced in ...
Creating 360-degree 3D content has gained traction in the past few years, being used for Virtual Reality environments. However, creating such content is challenging because it requires a multi-camera setup or a collection of images from different perspectives. This paper proposes 3D Pano Inpainting, a pipeline capable of transforming a single equir...
The objective of this project is to train a model that transforms a tree with its foliage into only its branch structure. This is achieved by employing machine-learning techniques, specifically Generative Adverserial Networks (GANs). By utilizing the proposed method, a predictive model is built that automatically minimizes its own error function th...
Trees are essential components of both real and digital environments. Therefore, it is important to have 3D models of trees that are of high quality and computationally efficient. One way to achieve this is by compressing a high-quality model using billboard rendering, which involves partitioning the tree into multiple planes to produce a similar r...
Extended Reality (XR) encompasses immersive technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), which blend the physical and digital worlds. For XR experiences to captivate users and seamlessly integrate with reality, photorealistic content is essential. Photorealism ensures that virtual elements convincingly ...
Modelling objects and simulating them do not always map to each other, and often requires defining additional information outside the scope of the original model to achieve an accurate simulation. For example: cables in \textit{AGX Dynamics} (a simulation library from Algoryx AB) are entirely defined by its physical parameters (e.g. Young's modulus...
The subject of the thesis consists in developing a new vision of 3D for monumental heritage. It is both to respond to questions in the art history by incorporating enriched visual information, and to the needs for scientific validation. For this, it relies on the spatial structuring offered by 3D for restitutions, to be a medium for aggregating the...
