3D Applications and Virtual Camera
Top, front, left, right, back, bottom, and isometric (a kind of angled bird's eye view) are all different angles from which a model can be viewed.
Since there are lines converging, objects appear the same size whether they are close or far away The advantages of this sort of viewpoint include the ease in which you can align objects.
However, one orthographic view by itself is fairly useless because you cannot tell depth.
Therefore, the best use of orthographic views is one in which you have multiple orthographic views open so that you can adjust the vertical aspects from one angle, the horizontal from another, and the depth from the third-a view for each dimension.
Most 3D applications allow you to place a virtual camera that you can move around within the digital space and look through.
Cameras are the views from which 3D projects are usually finally rendered and presented.
Because of this, most cameras present perspective views.
One of the most popular ways to view digital space is to have three orthographic views open (front, side, and top), and another view or camera view that is using perspective projection.
Computer "drawing" methods: As you give the computer directions on what to do in its digital space, the computer tries to let you know what is going on by drawing or rendering the information on your screen.
We have already looked at the ways the computer attempts to show the shapes of the objects, but there are also a variety of ways that it tries to show the form.
Rendering refers to the way the computer draws or paints the information it has on the projection plane (your computer screen).
3D is the process of creating the world and then telling the computer to paint it and how to paint it.
Sometimes, you will want the computer to paint or render for you in beautifully finished ways.
However, at other times, more informative forms of illustration will be necessary.
The most intuitive form of rendering is the various algorithms of shaded rendering.
Shaded rendering forms are those where you see an object that is shaded to show roundness of form, or source of light.
