Book excerpt: Abstract: "In this paper we study the following generalization of the classical hidden surface removal problem: given a set S of objects, a view point and a point light source, compute which parts of the objects in S are visible, subdivided into parts that are lit and parts that are not lit. We prove tight bounds on the maximum combinatorial complexity of such views and give efficient output-sensitive algorithms to compute the views for three cases: (i) S consists of non-intersecting triangles, (ii) S consists of horizontal axis-parallel rectangles, (iii) S is the set of faces of a polyhedral terrain."

Available in PDF, EPUB and Kindle. Book excerpt: Hidden surface removal is a computer graphics problem involving a great deal of computation. The problem involves two facets: determining which objects should appear in front of others (prioritization), and elimination of invisible portions of the objects through geometric calculations. Prioritization is accomplished using object space decomposition, which divides object space in a binary fashion such that the objects in a scene (or critical portions of those objects) occupy unique sub-volumes of the object space. An octal-tree is used to map the decomposition, and a simple traversal of the tree, with minor interruptions for more sophisticated decision-making, results in a stream of objects in priority order. The second phase of the hidden surface problem, removal of invisible portions of objects, often requires a great deal of computation. Parallel processing offers potential for savings in response time, and the second part of this thesis investigates a number of algorithms which attempt to take advantage of inherent concurrency. Three algorithms are presented: a quad-tree image space decomposition algorithm, a purely geometric algorithm, and an algorithm which combines ideas from the first two. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A Pascal based ACM proposed standard (CORE) graphics system from the University of Pennsylvania was converted to run on an 086/8087 microcomputer. Additionally, a non-restrictive full 3-D hidden surface removal algorithm for surfaces modelled by opaque polygons was implemented. This algorithm is an extension of the list priority algorithm created by Newell, Newell, and Sacha. By saving the priority list created by the algorithm from one batch of updates to the next, computational savings are possible. Although the present algorithm can only be used on raster type display surfaces, this algorithm could be used as a prelude to other scan line hidden surface removal algorithms to provide support for vector type displays.

Available in PDF, EPUB and Kindle. Book excerpt: What is Hidden Line Removal Solid objects are typically modeled as polyhedra in the field of three-dimensional computer graphics. Within a polyhedron, a face is a planar polygon that is surrounded by straight line segments that are referred to as edges. When attempting to imitate curved surfaces, a polygon mesh is typically used. It is necessary for computer programs that are used to create line drawings of opaque objects to have the capability of determining whether edges or sections of the edges are hidden by the object itself or by other objects. This allows for the edges to be clipped during the rendering process. The difficulty in question is referred to as hidden-line removal.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "We present an algorithm for the hidden-surface elimination problem for rectangles, which is also known as window rendering. The time complexity of our algorithm is dependent on both the number of input rectangles, n, and on the size of the output, k. Our algorithm obtains a trade-off between these two components, in that its running time is [formula], where 1 [less than or equal to] r [less than or equal to] log n is a tunable parameter. By using this method while adjusting the parameter r 'on the fly' one can achieve a running time that is O(n log n+k(log n/log(1+k/n))). Note that when k is [Theta](n), this achieves an O(n log n) running time, and when k is [formula] for any positive constant [epsilon], then this achieves an O(k) running time, both of which are optimal."

Download or read book Ray Shooting Depth Orders and Hidden Surface Removal written by Mark de Berg and published by Springer Science & Business Media. This book was released on 1993-08-30 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational geometry is the part of theoretical computer science that concerns itself with geometrical objects; it aims to define efficient algorithms for problems involving points, lines, polygons, and so on. The field has gained popularity very rapidly during the last decade. This is partly due to the many application areas of computational geometry and partly due to the beauty of the field itself. This monograph focuses on three problems that arise in three-dimensional computational geometry. The first problem is the ray shooting problem: preprocess a set of polyhedra into a data structure such that the first polyhedron that is hit by a query ray can be determined quickly. The second problem is that of computing depth orders: we want to sort a set of polyhedra such thatif one polyhedron is (partially) obscured by another polyhedron then it comes first in the order. The third problem is the hidden surface removal problem: given a set of polyhedra and a view point, compute which parts of the polyhedra are visible from the view point. These three problems involve issues that are fundamental to three-dimensional computational geometry. The book also contains a large introductory part discussing the techniques used to tackle the problems. This part should interest not only those who need the background for the rest of the book but also anyone who wants to know more about some recent techniques in computational geometry.
