PREVIOUS YEAR SOLVED PAPERS - July 2016 Paper 3
- Option : C
- Explanation :
- In perspective projection, if a line segment joining a point which lies in front of the viewer to a point in back of the viewer is projected to a broken line of infinite extent. This is known as topological distortion.
- In perspective projection (from 3D to 2D), objects behind the centre of projection are projected upside down and backward onto the view-plane. This is known as view confusion.
- Vanishing point: Where all parallel points appear to meet is called vanishing point.
- Perspective foreshortening: As we move from centre of projection size of object varies inversely with distance, this is known as perspective foreshortening.
So, option (C) is correct.
- Option : D
- Explanation :
- Hermite curves are generated using the concepts of interpolation.Correct
- Bezier curves are generated using the concepts of approximation.Correct
- The Bezier curve lies entirely within the convex hull of its control points.Correct
- The degree of Bezier curve does not depend on the number of control points.Incorrect
The degree of Bezier curve depends on the number of control points. So, option (D) is correct.
- Option : D
- Explanation :
- To implement Abstract Data Type, a programming language require a syntactic unit to encapsulate type definition.Correct
- To implement ADT, a programming language requires some primitive operations that are built in the language processor.Correct
- C++, Ada, Java 5.0, C#2005 provide support for parameterised ADT.Correct
So, option (D) is correct.
20. Match the following types of variables with the corresponding programming
| (a) Static variables | (i) Local variables in Pascal |
| (b) Stack dynamic | (ii) All variables in APL |
| (c) Explicit heap dynamic | (iii) Fortran 77 |
| (d) Implicit heap dynamic | (iv) All objects in JAVA |
- Option : C
- Explanation :
- Static variables are used in Fortran 77
- Stack dynamic are local variables in Pascal
- Explicit heap dynamic are all objects in JAVA
- Implicit heap dynamic are all variables in APL
So, option (C) is correct.
