Previous Year Question (PYQs)
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.
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.
Solution
When a triangle is clipped against a rectangular viewport, new vertices may be created at clipping boundaries.A triangle has $3$ sides initially.
After clipping with a rectangle, the resulting polygon can have at most $6$ sides.
So, Statement I is true.
In $3D$ graphics, perspective transformation involves division by depth value $z$.
Because of this division by $z$, the transformation is not linear in $z$.
So, Statement II is also true.
Hence, both Statement I and Statement II are true.
