MICROARCHITECTURE OF A HIGH THROUGHPUT TEXTURE MAPPING PROCESSOR FOR INTERACTIVE 3D GRAPHICS
Texture mapping provides realistic details without producing large quantities of geometric objects in real-time applications such as animation, virtual reality, scientific visualization and interactive 3D games. An implementation of hardware texture mapping at interactive rates for the mainstream …

The design and implementation of a 3D graphics pipeline for the raw reconfigurable architecture
… transform and lighting, perspective correct texture mapping, and depth buffering, and is intended to be used as a slave processor receiving rendering commands from a host system. The design process is described in detail, along with difficulties encountered along the way, and a comprehensive …

An enhance framework on hair modeling and real-time animation
… hair animation based on 2D representation and texture mapping. Due to its 2D nature, it lacks of the volumetric effect as the real hair. This thesis presents a technique to solve the problem. The hair is still modeled in 2D strip. However, each visible strip is warped into U-shape for rendering …

Color and form
… processing, geometrical modelling, and color/ texture mapping in a "subtractive" color system.

Human face modeling, analysis and synthesis
… model of a particular person can be created by mapping a generic 3-D face model to these feature points followed by texture mapping using the face images. A facial motion analysis scheme is used to obtain the motion parameters associated with the face model. Either two end frames or sequences of …

Surface modeling and rendering with line segments
… rendering, we extend the anti-aliasing theory in texture mapping to anti-aliased line segment rendering, and present an approximation algorithm to render high quality anti-aliased opaque, transparent and textured line segments in 3D models. The anti-aliasing rendering technique is empirically …

Understanding the Structure of 3D Shapes
… important in a number of applications, such as texture mapping, spline fitting and hex-meshing. The second part will focus on medial descriptors. In particular, two new algorithms for the generation of curve-skeletons will be presented. These methods are completely based on the visual appearance …

A projective approach to computer-aided drawing
… applied to drawing primitives using conventional texture-mapping techniques, thereby enriching drawings and providing another way of incorporating hand-drawn images. I demonstrate the system with a variety of drawings.

Creating Geo-specific Road Databases From Aerial Photos For Driving Simulation
… cross section profiles. In the phase of texture mapping, five major uniform textures are considered - pavement, white marker, yellow marker, concrete and grass. They are automatically mapped to polygons. In the chapter of results, snapshots of road/visual database are presented.

Charting Presence in Virtual Environments and its Effects on Performance
… visual display resolution, field of view, sound, textures, head-tracking, stereopsis, virtual personal risk, number of possible interactions, presence of a second user, and environmental detail. Participants performed a set of five tasks in the VE and rated perceived presence at the end of each …

Constrained parameterization with applications to graphics and image processing.
… the application of the foldover-free constrained texture mapping. The basic idea is to split the usual parameterization procedure into two steps, 2D parameterization with the constraints of convex boundaries and 2D re-parameterization with the interior positional constraints. Moreover, we further …

Morphological quantitation software in breast MRI: application to neoadjuvant chemotherapy patients
The work in this thesis examines the use of texture analysis techniques and shape descriptors to analyse MR images of the breast and their application as a potential quantitative tool for prognostic indication.Textural information is undoubtedly very heavily used in a radiologist’s decision making …

Computational Modelling and Treatment Optimization of Acute Endovascular and Respiratory Conditions
… novel search algorithm using 3D to 2D projection mapping was developed to determine the optimal placement of fenestrations on the endograft at reduced computational cost, and a bijective conformal mapping algorithm was developed for texture mapping of the fenestrations to the 3D aortic graft …

OPTIMIZATION OF PHOTOGRAMMETRIC 3D ASSETS
… reduce the fragmentation of photo-reconstructed texture atlases, producing a more compact UV-map encoding with significantly fewer seams while minimizing the resampling artifacts introduced when synthesizing the new texture images. Next, we design a method to address texturing defects. Our …
