• Name of the three font editing tools.
ResEdit, FONTographer
• Differentiate between serif and sans serif fonts.
Giving oneexampleSerif fonts has a bit of decoration at the end of the letter, but the serif font does not. The times, textbooks of the new century are examples of serif fonts. Arial, potima are examples for sansserif fonts
• Distinguish between the window port and the port of view?
A part of an image that is to be displayed in a window is known as a window port. The display area of the selected parts or the way the selected part is viewed is referred to as the viewport.
• Define the cut?
Clipping is the method of cutting a graphical screen that fits tune- ly to a predefined graphic region or viewport
• What is the need for homogeneous coordinates?
To perform more than one transformation at a time, use homogeneous coordinates or matrices. Reduce unwanted calculations, intermediate steps save time and memory and produce a sequence of transformations
• Distinguish between uniform scaling and differential scaling?
When the scaling factors sx and sy are assigned to the same value, a uniform scaling is produced which maintains the proportions of the representative objects. Unequal values for sx and syresult in a differential scaling that is often used in the design application
• What is the fixed-point scale?
The location of a scaled object can be controlled by the apposition called the fixed point that must remain unchanged after the scale transformation.
• What is the basic function of Bezier?
Bezier The basic functions are a set of polynomials, which can be used instead of the primitive polynomial base, and have useful properties for the design of interactive curves
• What is a surface patch? A single surface element can be defined as the surfacent as two parameters (u, v) take all possible values between 0 and 1 in a two-parameter representation. Such a simple surface element is known as a surface patch
• Define the B-Spline curve?
A B-Spline curve is a set of polynomial segments per piece (usually cubic) passing near a set of control points. However, the curve does not pass through the control points, only happens near them
• What is a spline?
To produce a smooth curve through a set of design points, a flexible strip called a spline is used. Said scan structure can be described mathematically with a polynomial function in the form of a homokinetic piece whose first and second derivatives are continuous through several sections of curves.
