Book excerpt: This thesis presents an expressive (non-photorealistic) rendering approach created by combining volumetric rendering techniques with the Line Integral Convolution (LIC) in 3D space. Although some techniques that combine volume rendering with the LIC have beenintroduced in computer graphics, they are mainly used for the scientific visualization fields, such as the visualization of 3D fluid fields. Unlike earlier research, we will focus on artistic representation, which is significantly different than scientific visualization research. We will implement a brush-stroke effect on the implicit surfaces by using the LIC. The implicit surfaces are described as volume datasets that are created by the voxelization of triangular meshes. To acquire smearing effects on the surface we convolve along the vector fields with the densities of the voxels of the datasets. These vector fields are defined by users as texture maps. The final images are rendered with volume ray casting, integrating colors and densities of voxels with Perlin noise along vector fields. The Perlin noise provides randomness and allows us to generate scratches. Smearing effects on the surfaceof an object create the illusion of 3D brush-strokes as if a painter had created brush strokes on a canvas. The rendering system is implemented using standard C and C++ programming languages. 3D models are then created using Alias Maya [superscript]TM and Topmod [superscript]TM.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "We present local and global techniques to visualize three-dimensional vector field data. Using the Line Integral Convolution (LIC) method to image the global vector field, our new algorithm allows the user to introduce colored 'dye' into the vector field to highlight local flow features. A fast algorithm is proposed that quickly recomputes the dyed LIC images. In addition, we introduce volume rendering methods that can map the LIC texture on any contour surface and/or translucent region defined by additional scalar quantities, and can follow the advection of colored dye throughout the volume."

Download or read book Illustrating Surface Shape in Volume Data Via Principal Direction-Driven 3D Line Integral Convolution written by Victoria L. Interrante and published by . This book was released on 1997 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "The three-dimensional shape and relative depth of a smoothly curving layered transparent surface may be communicated particularly effectively when the surface is artistically enhanced with sparsely distributed opaque detail. This paper describes how the set of principal directions and principal curvatures specified by local geometric operators can be understood to define a natural 'flow' over the surface of an object, and can be used to guide the placement of the lines of a stroke texture that seeks to represent 3D shape information in a perceptually intuitive way. The driving application for this work is the visualization of layered isovalue surfaces in volume data, where the particular identity of an individual surface is not generally known a priori and observers will typically wish to view a variety of different level surfaces from the same distribution, superimposed over underlying opaque structures. By advecting an evenly distributed set of tiny opaque particles, and the empty space between them, via 3D line integral convolution through the vector field defined by the principal directions and principal curvatures of the level surfaces passing through each gridpoint of a 3D volume, it is possible to generate a single scan-converted solid stroke texture that may intuitively represent the essential shape information of any level surface in the volume. To generate longer strokes over more highly curved areas, where the directional information is both most stable and most relevant, and to simultaneously downplay the visual impact of directional information in the flatter regions, one may dynamically redefine the length of the filter kernel according to the magnitude of the maximum principal curvature of the level surface at the point around which it is applied. Strokes are constrained in narrowness by the resolution of the volume within which the texture is represented, but may be variably widened, at the time of rendering, to reflect shading information or any other function defined over the volume data, by adaptively indexing into multiple pre-computed texture volumes obtained from advected particles of different sizes."

Available in PDF, EPUB and Kindle. Book excerpt: What Is Volumetric Display A volumetric display device is a graphic display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays create 3D imagery via the emission, scattering, or relaying of illumination from well-defined regions in (x,y,z) space. How You Will Benefit (I) Insights, and validations about the following topics: Chapter 1: Volumetric display Chapter 2: Photolithography Chapter 3: Holography Chapter 4: Stereoscopy Chapter 5: Voxel Chapter 6: Tomography Chapter 7: Display device Chapter 8: Scientific visualization Chapter 9: Optical coherence tomography Chapter 10: Volume rendering Chapter 11: Light field Chapter 12: Stereo display Chapter 13: Autostereoscopy Chapter 14: HoloVID Chapter 15: Holographic display Chapter 16: Structured-light 3D scanner Chapter 17: Spinning mirror system Chapter 18: Multiscopy Chapter 19: Microscanner Chapter 20: MotionParallax3D Chapter 21: Scanning Fiber Endoscope (SFE) (II) Answering the public top questions about volumetric display.

Download or read book Interactive 3D Line Integral Convolution on the GPU written by Vasumathi Lakshmanan and published by . This book was released on 2006 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Line Integral Convolution (LIC) is a mainstay of flow visualization. It is, however, computationally intensive, which limits its interactivity. Also, when used to view three-dimensional (3D) vector fields, the resulting images are dense and cluttered, making it difficult to perceive the flow on the interior parts of the field. This thesis describes research to make the 3D LIC more interactive by implementing it on the Graphics Processor Unit (GPU). It also includes methods to improve the clarity of the 3D LIC images. The volume dataset and a 3D noise volume are placed in GPU memory as 3D textures. The GPU is then used to perform the LIC computations and display the resulting volume. This allows the user to dynamically adjust LIC parameters and derive more insight into the 3D flow field. Various techniques such as introduction of sparsity and the use of stereographics help to de-clutter the scene. Resulting images and timing benchmarks are included.

Available in PDF, EPUB and Kindle. Book excerpt: Exciting developments in earthquake science have benefited from new observations, improved computational technologies, and improved modeling capabilities. Designing models of the earthquake generation process is a grand scientific challenge due to the complexity of phenomena and range of scales involved from microscopic to global. Such models provide powerful new tools for the study of earthquake precursory phenomena and the earthquake cycle. Through workshops, collaborations and publications, the APEC Cooperation for Earthquake Simulations (ACES) aims to develop realistic supercomputer simulation models for the complete earthquake generation process, thus providing a "virtual laboratory" to probe earthquake behavior. Part II of the book embraces dynamic rupture and wave propagation, computational environment and algorithms, data assimilation and understanding, and applications of models to earthquakes. This part also contains articles on the computational approaches and challenges of constructing earthquake models.

Available in PDF, EPUB and Kindle. Book excerpt: Today, many scientists in different disciplines realize the power of graphics, but are also bewildered by the numerous graphics tools. More often than not, they choose the improper software tools and end up with unsatisfactory results. This book introduces and categorizes the most commonly used graphics tools and their applications. The purpose is not to provide an exhausting list of tools and their explicit functions, but rather to provide scientific researchers with different means and application areas in computer graphics, so as to help them efficiently use visualization, modeling, simulation, and virtual reality to complement their research needs. This guide includes coverage of the most widely used commercial software, freeware and open-source software.
