You have written a collision-detection algorithm to find out whether a ball hits a wall.
However, the ball sometimes passes completely through the wall and no collision is
detected.
Which two reasons can explain this? (Choose two.)

What asset contains the individual frames of a 2D animation?

DRAG DROP
Match each collision-detection method to its description. (To answer, drag each method from
the column on the left to its description on the right. Each method may be used once, more
than once, or not at all. Each correct match is worth one point.)

Which formula should you use to find the distance between the two points (xl, yl, zl) and (x2,
y2, z2) in 3D space?

DRAG DROP
Match each GraphicsDevice method to its purpose. (To answer, drag each method from the
column on the left to its purpose on the right. Each method may be used once, more than
once, or not at all. Each correct match is worth one point.)

What are three ways to perform rotation in 3D space? (Choose three.)

Which two are the benefits of using a quaternion? (Choose two.)

DRAG DROP
You are writing per-pixel collision-detection code for a game in which two objects collide. All
requisite variables have been predefined.
Match each code segment to its action. (To answer, drag each code segment from the
column on the left to its action on the right. Each code segment may be used once, more
than once, or not at all. Each correct match is worth one point.)

This question requires that you evaluate the underlined text to determine if it is correct.
In the Direct3D transformation pipeline, the view transformation converts vertices that are in
the viewing frustum to screen space.

Select the correct answer if the underlined text does not make the statement correct. Select
“No change is needed” if the underlined text makes the statement correct.

The aspect ratio of the screen is described as the:
