What is the primary purpose of shadow mapping in game graphics?
-
To create realistic and accurate shadows
-
To improve the performance of lighting calculations
-
To reduce the number of polygons required to model an object
-
To enhance the realism and quality of textures
A
Correct answer
Explanation
Shadow mapping is a technique used to create realistic and accurate shadows by projecting the depth of objects onto a texture map.
What is the primary purpose of ambient occlusion in game graphics?
-
To create realistic shadows and highlights
-
To simulate the effects of global illumination
-
To add depth and dimension to objects
-
To enhance the realism and quality of textures
A
Correct answer
Explanation
Ambient occlusion is a shading technique that simulates the effects of ambient light being occluded by objects, resulting in more realistic shadows and highlights.

What is the purpose of the nodal point in panoramic photography?
-
It is the point where the optical axis of the lens intersects the plane of the sensor.
-
It is the point where the lens is attached to the camera body.
-
It is the point where the tripod is attached to the camera.
-
It is the point where the camera is positioned relative to the subject.
A
Correct answer
Explanation
The nodal point is the point where the optical axis of the lens intersects the plane of the sensor. It is important in panoramic photography because it is the point around which the camera rotates to create a panoramic image.
What is the primary function of a panoramic clamp?
-
It secures the camera to the tripod head.
-
It allows for precise rotation of the camera.
-
It compensates for lens distortion.
-
It helps to level the camera.
A
Correct answer
Explanation
