JNTU B.Tech III COMPUTER GRAPHICS Previous Question Paper (May/June - 2019 - R16)
Part A is compulsory (25 marks). Part B consists of 5 Units. Answer any one full question from each unit (10 marks each).
Part A
Define points and lines.
Answer
A point is the simplest geometric primitive representing a single coordinate position (x, y) in space. A line is a straight path connecting two distinct points, defined by the set of all points lying between its two endpoints.
Write the differences between a general graphics system designed for a programmer and one designed for a specific application, such as architectural design.
Answer
A general graphics system provides a broad set of low-level primitives and functions suitable for various applications, offering flexibility but requiring more complex coding. In contrast, an application-specific system (e.g., architectural design) provides high-level, domain-specific tools and pre-defined objects like walls, windows, and doors, which increases efficiency and ease of use for that specific task at the cost of general-purpose versatility.
