What is viewing transformation in 2D?
Transformation is a process of modifying and re-positioning the existing graphics. 2D Transformations take place in a two dimensional plane. Transformations are helpful in changing the position, size, orientation, shape etc of the object.
What is two dimensional viewing and clipping?
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.
What are the stages involved in 2D viewing transformation pipeline?
The viewing transformation which maps picture co-ordinates in the WCS to display co-ordinates in PDCS is performed by the following transformations. Converting world co-ordinates to viewing co-ordinates. Normalizing viewing co-ordinates. Converting normalized viewing co-ordinates to device co-ordinates.
What is viewing transformation?
Viewing Transformation is the mapping of coordinates of points and lines that form the picture into appropriate coordinates on the display device. World coordinate system (WCS) is the right handed cartesian co-ordinate system where we define the picture to be displayed.
What is 2D viewing and viewing pipeline?
█ 2D Viewing Pipeline. The term Viewing Pipeline describes a series of transformations, which are passed by geometry data to end up as image data being displayed on a device. The 2D viewing pipeline describes this process for 2D data: norm. object- world- viewing- device- device coord.
What is a viewing and clipping?
What is viewing and clipping? The objects, lines and the line segments which are not in the view pane and are outside the view pane are removed in computer graphics by using clipping.
What is viewing pipeline?
The term Viewing Pipeline describes a series of transformations, which are passed by geometry data to end up as image data being displayed on a device. The 2D viewing pipeline describes this process for 2D data: norm.
What is clipping operation in computer graphics?
Clipping, in the context of computer graphics, is a method to selectively enable or disable rendering operations within a defined region of interest. Mathematically, clipping can be described using the terminology of constructive geometry.
Why is viewing transformation needed?
Remember that purpose of the viewing transformation is to orient the objects in a coordinate system where the center of projection is located at the origin. This coordinate system is called either eye space or camera space.
Which of the following co ordinates are not used in 2D viewing transformation?
4. Which of the following co-ordinates are NOT used in 2d viewing transformation? Explanation: Vector co-ordinates are used to denote vectors which are physical quantities having magnitude as well as direction.
What is point clipping and line clipping?
In case of point clipping, we only show/print points on our window which are in range of our viewing pane, others points which are outside the range are discarded. Line clipping:- Line clipping is the process of removing lines or portions of lines outside an area of interest.
