In this project we have a plane, a sphere, a cylinder, and a cube. These objects represent the basic types of Texture Mapping in Electric Image. Let's open up the Material Window for the plane. This time we'll bypass the model's Info Window and Command double-click the model. Just hold down the Command key on your keyboard and double-click the model. That's a shortcut to the Material Window. In the Diffuse tab in our Texture list we see a single image. Let's turn on the Texture by clicking in the column next to it, and we have our back on, and this Texture's now being used by EI. Also, next to the name there's a very small Icon. It looks like a square. This Icon lets you know what kind of mapping is being applied to the image. The square means that a planar, or flat map type, is being used. Flat Mapping is the default Map type and will be used every time a new Texture is added. Of course, the Mapping Type can be changed. Double-click the name of the Texture and its Texture Window appears. Click the Projection tab and we see a popup menu for the Map Type. Click on this to reveal the basic types of Mapping techniques: Flat, Cylindrical, Spherical, and Cubic. Now let's visit each model in our scene. Command double-click on the sphere to open its Material Window and turn on its Texture. The Icon next to its name looks like a small sphere. Next, the cylinder Ð open its Material Window, turn on the Texture and see that its Icon looks like a small cylinder. And last, the cube Ð turn on its Texture and its Icon looks like a small cube. In the Camera Window we now see our models with their textures. The Mapping Types match the shape of the model, so for the sphere the map is applied with a spherical projection, the cylinder cylindrical, the cube cubic. You should choose a Mapping Type that matches the general shape of your model. Obviously I've got 3D primitives that are an exact match to the Mapping Types used, but think of a vase, for example. If it's a tall vase it might match the basic shape of a cylinder, so you might want to use Cylindrical Mapping. If your vase was short and round, or you wanted to texture a rock, then you might want to choose Spherical Mapping.
