3D Graphics

Prefab in Unity 3D is referred for pre-fabricated object template (Class combining objects and scripts). At design time, a prefab can be dragged from project window into the scene window and added the scene’s hierarchy of game objects. If desired the object then can be edited. At the run time, a script can cause a new object instance to be created at a given location or with a given transform set of properties.

AssetBundles are files that can be exported from Unity to contain asset of your choice. AssetBundles are created to simply downloading content to your application.

Just because this isn’t posed as a question, do not accept it as a fact. What is a fact is that despite a concern that you are overqualified, you still were granted an interview. Since interviewers don’t like wasting their time, this means they’re expecting you to answer this question well enough for them to justify hiring you.

Properties of video display devices are persistence ,resolution, and aspect ratio.

Computer graphics remains one of the most existing and rapidly growing computer fields. Computer graphics maybe defined as a pictorial representation or graphical representation of objects in a computer.

Fixed Timestep feature helps to set the system updates at fixed time interval. A queue like mechanism will manage all real-time events that are accumulated between time epochs. If frame-rate drops below some threshold limit set for fixed timestep, then it can affect the game speed.

Following are the advantages of electrostatic plotters-

☛ 1. They are faster then pen plotters and very high quality printers.

☛ 2. Recent electrostatic plotters includes a scan conversion capability.

☛ 3. color electrostatic plotters are available. They make multiple passes over the paper to plot color picture.

The ratio of vertical points to the horizontal points necessary to produce length of lines in both directions of the screen is called the Aspect ratio. Usually the aspect ratio is ¾.

Circle is defined by its center xc, yc and its radius in user coordinate units. The equation of the circle is (x-xc) + (yyc)= r2.

A 2-D rotation is done by repositioning the coordinates along a circular path, in the x-y plane by making an angle with the axes. The transformation is given by:X| = r cos (q + f) and Y| = r sin (q + f).

Features of inkjet printers are

☛ 1. They can print 2 to 4 pages per minute.

☛ 2. resolution is about 360d.p.i. Therefor better print quality is achieved.

☛ 3. The operating cost is very low. The only part that requires replacement is ink cartridge.

☛ 4. Four colors cyan, yellow, magenta, black are available.

The difficulty of this question is directly proportional to the amount of preparation you did. If you didn’t prepare at all, this question is impossible to answer.

Demonstrate your knowledge of the company and show the interviewer you did your homework by discussing how the company’s vision and mission align with your values. If you do this at all, let alone well, you will be able to succinctly explain why you would rather work for this company than for their competitor.

The Raster and Vector graphics can be explained as-

☛ RASTER- In computer graphics image, or BITMAP, is a dot matrix data structure representing a generally rectangular grid of pixels or points of color, viewable via a monitor, paper, or other display medium. Raster image are stored in image files with varying formats.

☛ VECTOR- Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon, which are all based on mathematical expressions, to represent image in computer graphics. “Vector”, in this context, implies more than a straight line.

The process of determining the appropriate pixels for representing picture or graphics object is known as rasterization.

The maximum number of points that can be displayed without overlap on a CRT is referred to as the resolution.

Some system has only one bit per pixel; the frame buffer is often referred to as bitmap.

Some system has multiple bits per pixel, the frame buffer is often referred to as pix map.
