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

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.

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.

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.

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.

Following are the applications of computer graphic
☛ 1. computer graphics is used in the field of computer aided design.
☛ 2. It is used to produce illustrations for reports or to generate slide for with projections.
☛ 3. Computer graphic methods are widely used in both fine are and commercial are applications.
☛ 4. The artist uses a combination of 3D modeling packages, texture mapping, drawing programs and CAD software.
☛ 5. In the field of entertainment CG methods are now commonly used in making motion pictures. music videos and television shows.
☛ 6. Computer-generated models of physical, financial and economic systems are often used as educational aids.

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).

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.

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.

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.
