   Nyckelord :Physically based animation; Soft body deformation; Volumetric models; GPU parallel computing;

   Sammanfattning : Background. Several methods have been used to simulate soft body deformation, such as mass-spring systems and position-based dynamics. This has been done using tetrahedral mesh models for preservation of shape and volume. LÄS MER

3. 7. Optimizing Realistic 3D Facial Models for VR Avatars through Mesh Simplification

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Beiqian Liu; [2023]
   Nyckelord :Mesh Simplification; Virtual Reality; Realistic Avatars; 3D Face Reconstruction;

   Sammanfattning : The use of realistic 3D avatars in Virtual Reality (VR) has gained significant traction in applications such as telecommunication and gaming, offering immersive experiences and face-to-face interactions. However, standalone VR devices often face limitations in computational resources and real-time rendering requirements, necessitating the optimization of 3D models through mesh simplification to enhance performance and ensure a smooth user experience.

4. 8. Evaluation of Physics Informed Neural Networks in engineering simple structural analysis problems

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Georgios Nentidis; [2023]
   Nyckelord :;

   Sammanfattning : Neural Networks have found many applications for a long time in Machine Learning in different disciplines, and have especially flourished in the last decade because of the ever-increasing processing power especially from GPUs. Because of their ability to operate as universal function approximators and model nonlinear processes, attempts have been made in recent years to be also used for modeling partial differential equation (PDE) solutions.

5. 9. Particle-Oriented Bounding Box Skeletal Animation in real-time applications

   Kandidat-uppsats, Blekinge Tekniska Högskola

   Författare :Simon Strand; Karlos Napa Häger; [2023]
   Nyckelord :Skeletal Animation; Particle; Velocity; Collision;

   Sammanfattning : Background. Skeletal animation is a technique used for displaying animated movement that uses bones in a hierarchy to get a structure; these bones are transformed based on their parent bones. Vertices in a mesh are connected to one or more bones with a weight, and the vertices will move based on the bone transformation, creating an animation. LÄS MER

7. 10. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Klara Lindroth; [2023]
   Nyckelord :automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

   Sammanfattning : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. LÄS MER
