Modeling & Texturing
Regardless of what kind of animation you are planning, the first thing you must do is create the objects you plan to use in your animation. In keeping with the live action metaphor, objects can be thought of anything that is in front of the camera, this includes actors, props, and scenery. Modeling is the process through which you can build all of the objects that does appear in your scene.
The easiest way top get started modeling is by using primitives which are simple 3D shapes that come with most software packages. These cubes, spheres, cylinders, cones, pyramids and planes can be combined to create more complex objects. This process is very much like building with blocks of legos. You don’t actually build the pieces you use you just put them together. Once you have built an object by combining some primitives it is likely you would want to link these together, so that whenever you move one piece the rest will move together. A second way to create a model is by starting in 2 dimensions. Almost every 3D package gives you the ability to draw a curve or a shape, manipulated and use it as a basis for creating a model. The types of curves you can create vary from program to program and each time has its own set up characteristics. In addition most software’s will allow you to import 2D curves from some other programs such as adobe illustrator. After creating a curve there are a number of ways to bring it into the third dimension. The simplest being revolving an extruding.
Once you have finished modeling you are ready to create the next step in the 3D process. If objects are your actors then textures are their costumes. While modeling defines the shape of your objects textures define what their surfaces look like there are 2 basic types of textures, materials and image maps. You will find that most projects both types of textures. Most programs come with a set up of materials that you can simply select from a menu and apply to your objects there is a wide variety of metal, stone, wood, skin, glass and liquid to choose from. As in the real world, materials differ from one another in a way that they reflect light. The different ways in which objects appear to the eye, say glass vs. metal, is the result of the combination of several different properties; these include colour , diffused shading, ambience shading, reflectivity and transparency. All of the pre made materials that come with software packages have these properties already defined. Glass is defined as transparent, partially reflective and a little diffused. Stainless steel is complete opaque, very reflective and barely diffused. These properties can be combined in an infinite no. of ways to produce any desired result.
Image maps are 2D images that are “placed” on the surface of the object. Image, maps can also be tile4d to cover an entire object. Some software packages also allow you to apply moving images as textures allowing you to map.
