Texture mapping overview
Texture mapping is a technique that uses images to add detail and texture to 3D objects. There are several types of texture mapping including bump mapping, normal mapping, parallax mapping, and displacement mapping. Bump mapping simulates bumps and wrinkles without changing the object's surface, while normal mapping is commonly used to fake lighting of bumps and dents. Parallax mapping enhances bump mapping techniques to give the illusion of depth as the viewing angle changes. Displacement mapping uses height maps to displace the actual geometry of surface points, giving surfaces great depth but at a higher computational cost.
Texture Mapping
Mip stands for the Latin multim im parvo, meaning "many things in a small place." Mipmapping uses some clever methods to pack image data into memory. When using mipmapping, OpenGL automatically determines which texture map to use based on the size (in pixels) of the object being mapped.
DPI 1 and DPI 2 Texture Mapping
Texture mapping is a graphic design process where a 2D texture map is wrapped around a 3D object to give it a surface texture. It accounts for the object's 3D position. Avatar used texture mapping extensively to create its virtual world. Textures played a key role in developing rich, varied character and environmental assets. Texture mapping techniques can also be applied to photography by layering texture photos over object photos, using layer masks and blending modes like Overlay. Warping and liquifying textures allows reshaping them to match the object. Students are assigned to take photos of textures and objects, then create texture maps by overlaying textures onto objects.
texture mapping in computer graphics
Texture mapping is a common method to add surface detail by mapping texture patterns onto object surfaces. The texture can be defined as a rectangular array or a procedure modifying surface intensity values. This approach, called texture mapping or pattern mapping, was illustrated by mapping a unit square pattern to a cylindrical surface through a series of linear transformations. Pixel positions were mapped to texture space and averaged to obtain each pixel intensity from the texture pattern.
Sprite Rendering
The document discusses the key steps and concepts involved in rendering sprites for games. It explains that rendering involves describing a virtual scene and camera, defining light sources and surface properties, and solving the render equation. It also discusses triangle meshes, texture mapping, 3D projection, coordinate systems, sprite components like transformation matrices, and orthographic projection. The overall rendering process for sprites involves applying transformations, scaling, rotation and translation to the sprites.
THE 3D MODELLING USING FRAME CAMERAS AND PANORAMIC CAMERA
The frame camera is used by users of digital single-lens reflex cameras (DSLRs) as a shorthand for an image sensor format which is the same size as 35mm format (36 mm × 24 mm) film.
Panoramic imagery is created either by digitally stitching together multiple images from the same position (left/right, up/down) or by rotating a camera with conventional optics, and an area or line sensor.

Accuracy Analysis of Three-Dimensional Model Reconstructed by Spherical Video...National Cheng Kung University
This document summarizes research analyzing the accuracy of 3D models reconstructed from spherical video images. The study acquired 134 spherical images of an indoor environment using a Garmin VIRB 360 camera. Images were extracted from video and reference points were collected. Aerial triangulation, dense image matching, and registration with TLS point clouds were performed. Results showed reconstruction accuracy was higher when reference points were distributed across images rather than clustered in the middle. However, the model had significant noise due to glass surfaces and stitching challenges. While geometric detail and accuracy were low, the 3D model could still enable some applications. Factors like calibration, stitching, resolution, and illumination variability affected the results.3D Indoor and Outdoor Mapping from Point Cloud Generated by Spherical Camera

Terms 3d-artist
Texture mapping involves adding graphics like photographs or designs to 3D polygon objects to make them appear more realistic. Shaders describe an object's material properties like how light is reflected. UV mapping projects a 3D model onto a 2D plane to make texture application easier. Specularity defines how surfaces reflect light to appear shiny. Normals indicate surface direction. Bump maps simulate small surface details without extra geometry. Transparency maps use black/white values to determine opacity. Normal maps store surface orientation data to mimic detail. Baking combines textures, materials, and lighting into single images to streamline rendering.
Color and appearance information in 3d models
This document discusses methods for representing color and visual appearance on 3D models. It describes how color is determined by the interaction of lighting and material properties. Common representations of visual appearance include reflectance functions, BSSRDFs, SVBRDFs and BRDFs. Texture mapping and color projection from photographs are introduced as ways to encode color information onto 3D geometry. Issues with photo shooting, registration, material estimation and color projection are discussed. The document recommends resources for learning more about these topics.

Double Patterning
Double patterning lithography is a technique used to print integrated circuit designs when feature sizes shrink below the resolution limits of a single exposure. It involves splitting the circuit layout into two masks and exposing the photo-resist layer twice to print the full design. Decomposing the circuit layout and assigning patterns to the two masks is an NP-hard graph coloring problem. The document describes techniques for decomposing the conflict graph that represents incompatible patterns, including using SPQR trees to decompose into tri-connected components and solving each independently. Experimental results show the proposed method can achieve a 3-10x speedup over other approaches.
Double Patterning (4/2 update)
This document discusses double patterning lithography techniques. It introduces how optical lithography is approaching its limits and double patterning is needed for smaller feature sizes. It describes the double patterning process and challenges including feature distortion and decreased yield. The document outlines techniques for polygon cutting, priority search trees, and decomposing conflict graphs into tri-connected components to solve the layout splitting problem. Experimental results on test cases including a 320k polygon design show the method achieves 3-10x speedup.

代表的なオープンソース空間データサーバの1つであるGeoServerは、多くの強力な機能を提供します。 特に、さまざまなデータソースからの空間データへの接続とパブリッシングをサポートします。 GeoServerはOpen Geospatial Consortiumによって地理空間フィーチャデータを要求するために設定された標準プロトコルであるWeb Feature Service（WFS）もサポートしています。 しかしながら、GeoServerは2次元ジオメトリのための関数しか提供しないため、3D空間データを処理する関数はほとんどありません。 GeoServerの重要なコンポーネントであるJTS Topology Suiteは3D空間操作をサポートしていないため、ソリッドジオメトリもサポートしていません。 この講演では、3D空間データを扱うために私たちが実装したGeoServerの拡張モジュールを紹介します。
GeoServer, one of the representative open source spatial data servers, provides many powerful features. In particular, it supports connecting to and publishing spatial data from a variety of data sources. GeoServer also supports Web Feature Service (WFS), which is a standard protocol established by the Open Geospatial Consortium to request geospatial feature data. However, GeoServer provides functions only for two-dimensional geometry, so it provides few functions for handling 3D spatial data. Because JTS Topology Suite, which is an important component of GeoServer, does not support 3D spatial operations, it also does not support solid geometries. In this talk, I will introduce extension modules of GeoServer that we have implemented to handle 3D spatial data.
Normal Mapping / Computer Graphics - IK
Normal mapping is a technique used in 3D computer graphics to add detail to 3D models without increasing the number of polygons. It works by encoding normal vector information for light calculation into RGB texture maps. This allows more detailed surface shapes and lighting than would be possible with just the base polygon mesh. The technique was introduced in the late 1990s and became widely used in video games starting in the early 2000s as hardware accelerated shaders became available, enabling real-time normal mapping rendering. It provides a good quality to performance ratio for complex surface details.

This document discusses several topics in image enhancement and processing including:
1. Spatial filtering which involves applying a weighted mask over an image to replace pixel values.
2. Logarithmic transformation which expands darker pixel values more than brighter ones for enhancement.
3. Thresholding, logarithmic transformation, negative transformation, contrast stretching, and grey level slicing as common nonlinear image transformations.
4. Weighted average filtering which applies different coefficients to pixels to give more importance to some over others.
5. High boost filters and unsharp masking as types of high pass sharpening filters used to highlight fine image details.

DPSNet is an end-to-end deep learning model that estimates dense depth maps from stereo image pairs. It generates cost volumes from multi-scale feature maps of reference and paired images. It then refines the cost slices with dilated convolutions considering contextual information. Finally, it regresses the depth maps from the initial and refined cost volumes. Evaluation on various datasets shows DPSNet achieves state-of-the-art performance in depth map estimation, outperforming other methods in terms of accuracy metrics while maintaining full completeness of predictions.

Know More About 3D Modeling
3D modeling involves using computer simulation software to mathematically represent real-life objects in three dimensions - width, height, and depth along the x, y, and z axes. There are two main types of 3D models: solid models, which show objects realistically for CAD, and shell boundary models, which show just the surface. 3D modeling is widely used in computer games, simulations, and other fields to create highly detailed and realistic looking 3D graphics, animations, and virtual objects.
TYBSC (CS) SEM 6- DIGITAL IMAGE PROCESSING
The document discusses image segmentation techniques. It defines image segmentation as partitioning a digital image into multiple segments or regions that are similar in characteristics such as color or texture. The main goal of image segmentation is to simplify an image into meaningful parts for analysis. Common techniques discussed include thresholding, clustering, edge detection, region growing, and neural networks. Thresholding uses threshold values to separate pixels into multiple classes or objects. Clustering groups similar image pixels together while edge detection finds boundaries between objects. The document also provides an example of the split and merge segmentation method.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
