Available in PDF, EPUB and Kindle. Book excerpt: What is Hidden Surface Determination In 3D computer graphics, hidden-surface determination is the process of identifying what surfaces and parts of surfaces can be seen from a particular viewing angle. A hidden-surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics. The process of hidden-surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. When referring to line rendering it is known as hidden-line removal. Hidden-surface determination is necessary to render a scene correctly, so that one may not view features hidden behind the model itself, allowing only the naturally viewable portion of the graphic to be visible.

Download or read book Computer Graphics from Scratch written by Gabriel Gambetta and published by No Starch Press. This book was released on 2021-05-13 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer Graphics from Scratch demystifies the algorithms used in modern graphics software and guides beginners through building photorealistic 3D renders. Computer graphics programming books are often math-heavy and intimidating for newcomers. Not this one. Computer Graphics from Scratch takes a simpler approach by keeping the math to a minimum and focusing on only one aspect of computer graphics, 3D rendering. You’ll build two complete, fully functional renderers: a raytracer, which simulates rays of light as they bounce off objects, and a rasterizer, which converts 3D models into 2D pixels. As you progress you’ll learn how to create realistic reflections and shadows, and how to render a scene from any point of view. Pseudocode examples throughout make it easy to write your renderers in any language, and links to live JavaScript demos of each algorithm invite you to explore further on your own. Learn how to: Use perspective projection to draw 3D objects on a 2D plane Simulate the way rays of light interact with surfaces Add mirror-like reflections and cast shadows to objects Render a scene from any camera position using clipping planes Use flat, Gouraud, and Phong shading to mimic real surface lighting Paint texture details onto basic shapes to create realistic-looking objects Whether you’re an aspiring graphics engineer or a novice programmer curious about how graphics algorithms work, Gabriel Gambetta’s simple, clear explanations will quickly put computer graphics concepts and rendering techniques within your reach. All you need is basic coding knowledge and high school math. Computer Graphics from Scratch will cover the rest.
Download or read book Hidden Line Removal written by Fouad Sabry and published by One Billion Knowledgeable. This book was released on 2024-05-05 with total page 109 pages. 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. How you will benefit (I) Insights, and validations about the following topics: Chapter 1: Hidden-line removal Chapter 2: Painter's algorithm Chapter 3: Computational geometry Chapter 4: Ray casting Chapter 5: Hidden-surface determination Chapter 6: Point location Chapter 7: Euclidean minimum spanning tree Chapter 8: Art gallery problem Chapter 9: High-dynamic-range rendering Chapter 10: Straight skeleton (II) Answering the public top questions about hidden line removal.

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.
Download or read book Hidden Surface Removal Through Object Space Decomposition written by Robert Monroe Simmons and published by . This book was released on 1982 with total page 256 pages. 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: We present three applications of this general technique: (i) For disks (or balls in space) we have U(n) = O(n), thus the visibility map can be computed in time O((n + k)log2 n). (ii) For 'fat' triangles (where each internal angle is at least some fixed [theta] degrees) we have U(n) = O(n loglog n) and the algorithm runs in time O((n loglog n + K)log2n). (iii) The method also applies to computing the visibility map for a polyhedral terrain viewed from a fixed point, and yields an O((n[alpha](n) + k)log n) algorithm."
