Hierarchical levels of details (HLODs) have proven to be an efficient way to visualize complex environments and models even in an out-of-core system. Large objects are partitioned into a spatial hierarchy and on each node a level of detail is generated for efficient view-dependent rendering. To ensure correct matching between adjacent nodes in the hierarchy care has to be taken to prevent cracks along the cuts. This either leads to severe simplification constraints at the cuts and thus to a…

Hlod refinement driven by hardware occlusion queries

TLDR
A novel error metric is introduced, taking visibility information (gathered from HOQs) as an integral part of refining an HLOD model, this being the first approach within this context to the best of the authors' knowledge.

Real-time appearance preserving out-of-core rendering with shadows

TLDR
A novel LOD selection and prefetching method for real-time rendering of hard shadows that entirely runs on a single CPU system is presented.

Real-time out-of-core trimmed NURBS rendering and editing

TLDR
A high quality, out-ofcore trimmed NurBS rendering algorithm that supports both an automatic preprocessing of gigabyte sized models and a real-time rendering of the preprocessed models allowing for the seamless integration of interactive editing of the NURBS surfaces is presented.

High qualitiy simplification and repair of polygonal models

TLDR
Of the three mesh simplification approaches presented here, the first one attempts to simplify polygonal models with the highest possible quality, the second, applies the developed technique to out-of-core simplification, and the third, prevents selfintersections of the model surface that can occur duringMesh simplification.

A high quality end-to-end out-of-core mesh simplification algorithm that is capable to guarantee a given geometric error compared to the original model and that uses a high quality simplification method during the whole reduction.

Towards predictive rendering in virtual reality

TLDR
This thesis briefly introduces the necessary background and identifies the steps required for real-time predictive image generation, and existing techniques targeting these steps are presented and novel techniques proposed to solve some of the remaining problems.

RealReflect - Real-time Visualization of Complex Reflectance Behaviour in Virtual Protoyping

TLDR
The RealReflect project is an endeavor to increase the realism of VR technology to levels where it can be used for meaningful qualitative reviews of real objects and provides a considerable benefit to those VR users groups who routinely have to make important design decisions about object appearance long before the actual product is first assembled.

Fat Borders : Gap Filling For Efficient View-dependent LOD Rendering

TLDR
A novel solution to the gap problem of deformable trimmed NURBS models with dynamic neighbourhood in real-time by combining the new gap filling algorithm with an on-the-fly tessellation of the individual trimmed NurBS patches.

This paper defines efficient refinement criteria based on the view frustum, surface orientation, and screen-space geometric error, and develops a real-time algorithm for incrementally refining and coarsening the mesh according to these criteria.

Adaptive Real-Time Level-of-Detail-Based Rendering for Polygonal Models

TLDR
The approach is more effective than the current level-of-detail-based rendering approaches for most scientific visualization applications, where there are a limited number of highly complex objects that stay relatively close to the viewer.

TLDR
This paper presents a method for performing adaptive simplification of polygonal meshes that are too large to fit in-core, and exhibits output-sensitive memory requirements and allows fine control over the size of the simplified mesh.

A cubic‐spline‐based distance metric is proposed that can be used to unify the geometry and topology simplifications by considering the vertex positions and normals in an integrated manner.

View-dependent simplification of arbitrary polygonal environments

TLDR
HDS is dynamic, retessellating the scene continually as the user's viewing position shifts, and global, processing the entire database without first decomposing the environment into individual objects.
