3D Graphics

The term computer graphics include almost every thing on computer that is not text or sound. It is an art of drawing pictures, lines. charts, etc. using computers with the help of programming. Or we can say that graphics is the representation and manipulation of image data by computer with the help from specialized software and hardware. Graphic designing is done using the various available softwares for computers which can produce the 3D images in the required shape and dimension. Computer graphics help us in getting the real display experiences.

To hide gameobject in Unity 3D, you have to use the code

gameObject.transform.SetActive(false);

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).

A special purpose processor, which is used to control the operation of the display device, is known as video controller or display controller.

In the CRT, heat is applied to the cathode by directing a current through a coil of wire, is called filament

Impact printer press formed character faces against an inked ribbon on to the paper. A line printer and dot-matrix printer are examples. on-impact printer and plotters use Laser techniques, inkjet sprays, Xerographic process, electrostatic methods and electro thermal methods to get images onto the papers. Examples are: Inkjet/Laser printers.

Beam penetration method, shadow mask method.

Video controller is used to control the operation of the display device. A fixed area of the system is reserved for the frame buffer, and the video controller is given direct access to the frame buffer memory.

Unity 3D is a powerful cross-platform and fully integrated development engine which gives out-of-box functionality to create games and other interactive 3D content.

When a key is pressed on the keyboard, the keyboard controller places a code carry to the key pressed into a part of the memory called as the keyboard buffer. This code is called as the scan code.

The process of adjusting intensities of the pixels along the line to minimize the effect of aliasing is called ant aliasing.

In plasma panel display, the region between two glass plates is filled with neon gas. In thin film electroluminescent display, the region between two glasses plates are filled with phosphor, such as zinc sulphide doped with manganese.

A Unity3D files are scene web player files created by Unity; an application used to develop 3D games. These files consist of all assets and other game data in a single archive, and are used to enable gameplay within a browser that has the Unity Web Player Plugin. The assets within a 3D unity file are saved in a proprietary closed format.

A major task of the display processor is digitizing a picture definition given in an application program into a set of pixel-intensity values for storage in the frame buffer. This digitization process is called scan conversion.

The merits and demerits of direct view storage tubes[DVST] are as follows. It has a flat screen. Refreshing of screen is not required. Selective or part erasing of screen is not possible. It has poor contrast Performance is inferior to the refresh CRT.

A line is of infinite extent can be defined by an angle of slope q and one point on the line P=P(x,y). This can also be defined as y=mx+C where C is the Y intercept.

The line type, width and color are the attributes of the line. The line type include solid line, dashed lines, and dotted lines.

The merits and demerits of the Penetration techniques areas follows. It is an inexpensive technique. It has only four colors. The quality of the picture is not good when it is compared to other techniques. It can display color scans in monitors. Poor limitation etc.

In raster scan display, at the end of one frame, the electron beam returns to the left top corner of the screen to start the next frame.
