What is canonical view volume in computer graphics?
Likewise, what is view volume in computer graphics?
The volume of space that is actually rendered into the image is called the view volume. Things inside the view volume make it into the image; things that are not in the view volume are clipped and cannot be seen. For purposes of drawing, OpenGL applies a coordinate transform that maps the view volume onto a cube.
Similarly, what is viewing in computer graphics? The two dimensional viewing is a transformation process of real world object into position point which is relative to the viewing volume, especially, the points behind the viewer. Clipping is a computer graphics process to remove the lines, objects, or line segments, all of which are outside the viewing pane.
In respect to this, what is view volume?
The view volume defines the three-dimensional volume in space that, once projected, is to fit within the viewport. There are two parts to the view volume: the viewplane rectangle and the near and far clipping planes.
What is projection and types of projection in computer graphics?
Projection is defined as mapping of an object point P(X ,Y, Z ) into its imageP'(X' ,Y', Z' ) on the viewing surface called view plane or projection plane . Here the third coordinate of the projected image Z' will be zero and 'll be used for depth information.
