Adobe Photoshop is the graphic arts industry standard software for raster image manipulation. Cartographers can also use Photoshop to create effective colored shaded relief for maps.

One important advantage in using Photoshop to create shaded relief is that of familiarity. Most cartographers and graphic artists have Photoshop on their desktop and are skilled in using it for working with images. It is an extremely powerful image-editing tool and a skilled cartographer can make many enhancements to a shaded relief map image once it is rendered.

Before we get into Photoshop I’m going to present to you an idea of what layers are about. If we take a layer of thin glass, and paint a pattern onto it, we can think of it as a single layer! Here you can see that we’ve painted a nice red rectangle onto our sheet of glass. If we put a paint a second (new) sheet of glass with a green circle on it, and place it over the first sheet, where we haven’t painted will show through the second sheet of glass (i.e. we will see the red square).

This piece of article will show you step by step of how the dragon is created using Maya. There are three type of modeling method in Maya, NURBS modeling, Subdivision modeling and Polygon modeling, each of them have their advantages and disadvantages. However we will build the dragon using patch NURBS surface techniques. The tools that I use to model this dragon are Birail tools, NURBS primitive, Fillet Blend Tools and etc.

The content of data production in 3D city model is 3D Model Data (3DMD) including Digital Elevation Model (DEM), Digital Orthoimage Map (DOM) and objects (artificial and natural objects). DEM and DOM should be produced according to the traditional and mature criterion. 3D city model data production based on aerial remote sensing and 2DGIS should include three aspects: aerial survey 3D geometry model building, field texture collecting and building, terrain sight building and CAD model building for parts of objects.

This tutorial covers the basics of how to setup and bake ambient occlusion maps in Maya8. The process is similar for previous versions of Maya only the menu names will be different. As with most things in Maya there are probably many different ways to do this but this method works well for me and is reasonably quick to setup.

AutoCAD is the world’s most popular computer-aided drafting software product for the personal computer available in both DOS and windows by Autodesk, Inc. Anything that can be drawn on a drawing board can be drawn by AutoCAD.

AutoCAD is an interactive drawing system designed to permit a user to construct or edit a drawing on a graphics display screen. It is similar to other word-processing programs except that in this case the thing being processed is a drawing. Each drawing is stored on a disk file, and AutoCAD is only able to edit one drawing at a time. An AutoCAD drawing is made up of entities. All the objects in the drawing space are considered entities such as lines, arcs, circles, text, and so on or blocks (which are groups of entities).

This tutorial covers ways to create a terrain and control a flow of particle moving on the terrain in Virtools. Textured dunes: download at http://www.tinkering.net/sciviz/terraindune.cmo The landscape is created With Dune color, for texture and with Dune black-and-white, for displacement map. Please note that the pictures can be created in Photoshop or from a digital camera. You can use the same image for a texture and for a displacement map. You may end up using a black and white image for the displacement map because sometimes you want to have more control over the topography.
