Q74.Marks: +2.0UGC NET Paper 2: Computer Science 26th Nov 2021
Given below are two statements
Statement I : The maximum number of sides that a triangle might have when clipped to a rectangular viewport is 6.
Statement II : In 3D graphics, the perspective transformation is nonlinear in z.
In light of the above statements, choose the correct answer from the options given below
1.Both Statement I and Statement II are true.
2.Both Statement I and Statement II are false
3.Statement I is true but Statement II is false
4.Statement I is false but Statement II is true✓ Correct
Solution
The correct answer is option 4.
Concept:
Statement I: The maximum number of sides that a triangle might have when clipped to a rectangular viewport is 6.
False,The maximum number of sides that a triangle might have when clipped to a rectangular viewport is 7. Here is an example of the above statement.
Statement II: In 3D graphics, the perspective transformation is nonlinear in z.
True, In 3D graphics, A linear projection in which three-dimensional objects are projected on a picture plane is called perspective projection or perspective transformation. As a result, faraway items look smaller than objects closer to the viewer. Perspective transformation is a non-linear transformation and the perspective transformation is nonlinear in z.
Hence the correct answer is Statement I is false but Statement II is true.
