A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture . They may be stored in common image file formats , referenced by 3D model formats or material definitions , and assembled into resource bundles .
The purpose of this tutorial is to show how to create a vector graphics topological map of a single rapid transit, tram, railway, waterway, road or long footpath, etc, route. Topological maps are straight-line diagrams or schematics that display not only the routes, but also other information such as stations and travel zones (as in the case of ...
Ray-traced model demonstrating specular reflection. Reflection in computer graphics is used to render reflective objects like mirrors and shiny surfaces. Accurate reflections are commonly computed using ray tracing whereas approximate reflections can usually be computed faster by using simpler methods such as environment mapping.
Cube maps provide a fairly straightforward and efficient solution to rendering stable specular highlights. Multiple specular highlights can be encoded into a cube map texture, which can then be accessed by interpolating across the surface's reflection vector to supply coordinates. Relative to computing lighting at individual vertices, this ...
Specular highlights are high and realistically modeled at the appropriate edge of the tread using a normal map. Physically based rendering (PBR) is a computer graphics approach that seeks to render images in a way that models the lights and surfaces with optics in the real world. It is often referred to as "Physically Based Lighting" or ...
An environment texture mapped onto models of spoons, to give the illusion that they are reflecting the world around them. In computer graphics, reflection mapping or environment mapping [1] [2] [3] is an efficient image-based lighting technique for approximating the appearance of a reflective surface by means of a precomputed texture.
In fact "Specular" is defined in optics as Optics. (of reflected light) directed, as from a smooth, polished surface (opposed to diffuse). A specular surface is a highly smooth surface. When the surface is very smooth, the reflected highlight is easy to see. As the surface becomes rougher, the reflected highlights gets broader and dimmer.
Producing maps with xplanet is a wikipedia tutorial showing how to use xplanet as a piece of GIS kit, to make map images suitable for use on wikipedia and other such websites. By the end of the tutorial, you should be able to quickly and accurately produce maps of any region suitable for publication.
