1 :: Write The Properties Of Video Display Devices?

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

2 :: Tell me what is the use of AssetBundle in Unity3D?

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.

3 :: Tell us what is Prefabs in Unity 3D?

Prefab in Unity 3D is referred for pre-fabricated object template (Class combining objects and scripts).

7 :: What Is Scaling?

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).

8 :: Define Me Circle?

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.

9 :: What Is Aspect Ratio?
