BSCS Bachelor of Science in Computer Science: Computer Graphics Fundamentals Questions 4

Question 1

Which matrix operation converts a point from world space to camera (view) space?

Accepted Answer

View matrix

Answer

The view matrix repositions world-space coordinates relative to the camera's position and orientation.

Question 2

In the graphics pipeline, what is the role of the fragment shader?

Accepted Answer

Compute the final color of each rasterized pixel

Answer

The fragment shader runs once per rasterized fragment and outputs the final color (and optionally depth) for that pixel.

Question 3

What is Phong shading's key advantage over Gouraud shading?

Accepted Answer

It interpolates normals across the surface, producing more accurate specular highlights

Answer

Phong shading interpolates surface normals across each polygon and evaluates lighting per-fragment, producing sharper, more realistic specular highlights.

Question 4

Which data structure efficiently tests ray-triangle intersections by partitioning scene geometry?

Accepted Answer

Both B and C are correct

Answer

Both BVH and k-d trees are spatial acceleration structures that partition scene geometry to reduce the number of ray-triangle intersection tests.

Question 5

What does 'gimbal lock' refer to in 3D rotation systems?

Accepted Answer

Loss of one degree of freedom when two rotation axes align

Answer

Gimbal lock occurs when two rotation axes of an Euler-angle system become coplanar, collapsing three degrees of freedom to two.
