Question

[Lê Quỳnh Anh]

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  Animation traditionally is done by hand-drawing or painting successive frame of an object, each slightly different than the proceeding frame. In computer animation, although the computer may be the one to draw the different frames, in most cases the artist will draw the beginning and ending frames and the computer will produce the drawings between the first and the last drawing. This is generally referred to as computer-assisted animation, because the computer is more of a helper than an originator.

  In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity

information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.

  High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.

          A camera can be used to film directly from the computer’s display screen, but for the highest quality images possible, expensive film recorders are used. The computer computers the positions and colors for the figures in the picture, and sends this information to the recorder, which captures it on film. Sometimes, however, the images are stored on a large magnetic disk before being sent to the recorder. Once this process is completed, it is replaced for the next frame. When the entire sequence has been recorded on the film, the film must be developed before the animation can be viewed. If the entire sequence does not seem right, the motions must be corrected, recomputed, redisplayed, and rerecorded. This approach can be very expensive and time - consuming. Often, computer-animation companies first do motion tests with simple computer­generated line drawings before selling their computers to the task of calculating the high-resolution, realistic-looking images.

According to the passage, in computer-assisted animation the role of the computer is to draw the ______________      .

A. first frame

B. middle frames

C. last frame

D. entire sequences of frames

Answer 1

[Dương Hoàn Anh]

Đáp án B.

Key words: computer - assisted animation, role of computer, draw.

Câu hỏi: Theo đoạn văn, trong mô hình hoạt hình hỗ trợ máy tính thì vai trò của máy tính là vẽ gì?

Clue: “In computer animation, although the computer may be the one to draw the different frames, in most cases the artist will draw the beginning and ending frames and the computer will produce the drawings between the first and the last drawing”: Trong hoạt hình máy tính, mặc dù máy tính có thể vẽ những khung hình khác nhau, trong nhiều trường hợp, họa sĩ sẽ vẽ khung hình đầu và cuối và máy tính sẽ sản xuất những bức hình ở giữa.

Do đó, chọn đáp án B. middle frames: Các khung hình ở giữa.

Các đáp án khác không phù hợp:

  A. first frame: khung hình đầu tiên

   C. last frame: khung hình ở cuối

   D. entire sequences of frames: tất cả chuỗi khung hình
