Graphics Designing

Question: What does the term "constraint" imply?
A
A graphics processing technique that simulates transparency or translucency for objects in a 3D scene to create visual effects like smoke, glass, or water.

B
The section of the graphics memory that stores the stencil data.

C
A rule or condition that must be followed regarding how the individual objects within an graphic can or cannot move, such as a wrist having to be attached to both a hand and an end of the lower arm.

D
Memory that is dedicated to the graphics processor and used to store rendered pixels before they are displayed on the monitor.

Question: What is meant by the term fog?
A
The mixing of an image with a fixed color that thickens as the image's pixels get further away from the viewpoint.

B
A special type of channel used in graphics software for saving selections.

C
a technique of blending bitmap-based images and text to reduce the stair-stepping or jagged appearance.

D
The relationship of an image's width to height or its proportions.

A
Image that continues from one page of a publication across the gutter or spine to the facing page.

B
The stair-step effect seen along curves and edges in text or bit-mapped graphics.

Question: The first procedure in the OpenGL pipeline is to transform a 3-D point that is defined in the object coordinate system into the world coordinate system. This step has three possible transformations: rotation, scaling, and translation. Which one of those below is typically the correct order for executing these three transformations?
A
First rotation, then translation, and then scaling.

B
First scaling, then rotation, and then translation.

C
First translation, then scaling, and then rotation.

D
First scaling, then translation, and then rotation.

Question: Which of the following best describes the term "vertex-vertex polygon mesh?"
A
A process by which color information is interpolated across the face of the polygon to determine the colors at each pixel.

B
A method of using two buffers, one for display and the other for rendering.

C
The simplest mathematical representation of a mesh, but which is not widely used due to the lack of explicit face and edge information.

D
A method of increasing the quality of a texture map by applying different-resolution texture maps for different objects in the same image, depending on their size and depth.
