Visualization of SDF Based Scenes
Fusek, Petr ; Karas, Matej (oponent) ; Milet, Tomáš (vedoucí práce)
Signed Distance Fields (SDF) provides an alternative method of describing 3D surfaces. A surface is represented by an SDF function that returns the distance to the nearest point on the surface. These functions can be combined using techniques similar to Constructive Solid Geometry (CSG). However, ray-casting algorithms commonly used to visualize these models are not scalable enough to render large and complex scenes with many SDF objects in real time. Inspired by the Dreams game and the GigaVoxel technology, this thesis presents a data structure for representing and creating 3D models using the aforementioned SDF-CSG method, along with a real-time rendering technique capable of rendering scenes with a large number of these objects using a Sparse Voxel Octree (SVO) data structure evaluated on a GPU in real-time. The rendering uses Level Of Detail (LOD) techniques and a view frustum culling algorithm to select visible SDF blocks with a level of detail proportional to the distance from the camera. An application developed in Rust using the wgpu graphics API allows the creation of these SDF models and demonstrates the introduced rendering techniques. This application could serve as a basis for future development of a simple 3D tool for artists looking for an alternative to traditional polygonal modeling.
