In-Depth Information
Photoshop can treat these cameras as diferent viewing angles for the model
when you import the model to Photoshop as a 3DS ile.
In Chapter 10, I talk about camera and views in 3D scenes, and we cover two
issues: the views of the camera and the properties of the camera.
Camera Views
The camera views are like moving your camera to reveal unseen parts of the
scene or model; these views can reveal only one side of the mode, when
the camera is typically vertical to the model side, or multiple sides, when the
camera views the model at a slope. You can set the camera view to show
the top, bottom, right, left, front, or back view.
The camera views are like having presets for the diferent positions of the
camera—without the need to move the camera manually to reach this
position. For example, if you choose the top view, you would view only the
parts of the model that can be seen from the top. This applies to the other
views, such as the side, bottom, right, and left as well.
Camera Features
When you create a camera or choose a camera to view a 3D object, there are
some features associated with the camera that let you control the camera.
To get a better understanding of the camera features, compare it with the
features and capabilities that you might have with a real camera; these
features include the ability to zoom and to use the camera to navigate
around the object, such as panning, walking around the object, and
rotating the camera around the object, which is known as
orbiting
.
Light
Of all the 3D terms, light takes top billing, based on its importance on the 3D
scene and for 3D models. The light makes us see objects; when light falls
over an object, it relects of it and to our eyes, to let us see things and feel
the depth of the object.
Light afects a 3D scene or 3D object based on the light's properties, such
as the softness, the intensity, and the type of the light. On the other
hand, the light is afected by the object's material, color, type of texture,
and details.
Light is critical to create a good design. However, it is essential not only in
regard to the technical parameters assigned, but also its placement and how
it afects the visual composition in total.
When you do not create a light source for a 3D scene or object, global light
sources are created by default. These default lights are helpful in viewing the
3D object and in the inal output for the project. But adding your own light
