Question: what is a ambeant acclusion?

Answer: Ambient occlusion is a shading method used in 3D computer
graphics which helps add realism to local reflection models
by taking into account Source: CoolInterview.com
Question: How to optimize an animated GIF?

Answer: Using fewer colors allows reducing the file size.
Limiting colors and using similar colors from frame to frame.To decrease the file size, one more method is to cut down the pixel dimensions.
The number of frames should be the exact number for the specified animation.

- Identify the file reduction feature in the software that creates GIF image files.

- Implement dithering. Dithering reduces the banding. The image appears smoother by eliminating colors Source: CoolInterview.com
Question: What are known as Image Blocks?

Answer: Image Block is the actual image.

The size of the image can be of any size.

The palette of the image can be of any size.

Other information includes:
1. Size of the picture in pixels.
2. Position of the image on Logical Screen
3. Local palette for the image.

The size of the image cannot be modified.

Changing the image size cases data corruption. Source: CoolInterview.com
Question: What do you mean by Persistence of Vision, in case of GIF Animation?

Answer: A phenomenon of the eye. By this an after image is persisted approximately 1/20th of a second on the retina. Human perception of motion is the end result of vision persistency. Visual form of memory that is referred as Iconic Memory is the cause of Persistence of Vision. The persistence of vision has two distinct illusions ? 1. Phi Phenomenon and 2. Beta Movement. Source: CoolInterview.com
Question: What is Interlacing in case of GIF Animation?

Answer: Displaying of a single frame of video into two frames.Each frame is split into alternating lines.
The first frame displays odd numbered lines, and the second frame displays even numbered lines. The resolution per frame is 480 horizontal lines.
The number of frames displays per second would be 30. Source: CoolInterview.com
Question: What is Simulation in case of GIF Animation?

Answer: An Imitation from real is known as Simulation.

The participating systems may be abstract or physical.

A specific modeling can well be supported by simulation.

By simulation, acquiring and getting information is simple and quick. Source: CoolInterview.com
Question: What are the alternatives to GIF?

Answer: PNG:

GIF images are limited to 256 colors.

PNG format supports palette-based images, Gray Scale images.

PNG also supports full color non palette based RGB images.

PNG format is suitable for transferring images on internet.

PNG is not for professional-quality print graphics.

MNG:

MNG is closed to PNG format.

Better compression standard than GIF

Integration of PNG and JPEG based images.

Supports transparent JPEG images. Source: CoolInterview.com
Question: Where is GPT stored?

Answer: GIF Format:

LZW compression standards are used in GIF images.

Traces the colors of the image and reduces the size of the file.

Best suited for simple animated graphics on the web.

PNG Format:

PNG(Portable Network Graphics) is a graphic file format for lossless compression.

It is suitable for raster images storage.

Indexed-color, grayscale and true color images are supported in PNG format.

Supports cross platform image brightness and color c Source: CoolInterview.com
Question: What is Logical Screen Descriptor (LSD)?

Answer: It is always a second block in GIF file.

An area of pixels usually referred as screen, is defined by Logical Screen Descriptor (LSD).

GIF file size is defined by this area.

When the logical screen is larger than the image, some space is displayed around the image.

As per the size of the images, the logical screen size need to be set based on the width and height of the images. Source: CoolInterview.com
Question: What is the purpose of Global Color Table (GCT) in GIF Animation?

Answer: Global Color Table (GCT) is represented by a sequence of bytes that represents Red, Green and Blue color triplets. Global Color Table is used for images with plain text extensions. Every global color table?s presence is marked by the Global Color Table Flag. The GCT Flag is set to 1 in Logical Screen Descriptor. The block contains the number of byes equal to 3 x 2 size of global color table + 1. One Global Color Table is present per Data Stream. Source: CoolInterview.com
Question: What is the arc in animation?

Answer: arc is known as a curve which determine the poses of the character, it is the most important concept for animation.
To get good knowledge on arc u must have drawing skills
Source: CoolInterview.com
Question: Explain what information Logical Screen Descriptor (LSD) of GIF files has?

Answer: Logical Screen Descriptor has the following information.

Logical Screen Width: The width of the image that represents in pixels

Logical Screen Height: The image height in pixels.

Packed Field: The element of the image for animation.

Background Color Index: A value that is pointing to a color in the Global Color Table.

Pixel Aspect Ratio: The approximate aspect ratio of the pixel in the GIF image. Source: CoolInterview.com
Question:
what is animation?


Answer: Animation is the rapid display of a sequence of images of 2-
D or 3-D artwork or model positions in order to create an
illusion of movement. Source: CoolInterview.com
Question: What is the File Structure of GIF?

Answer: GIF file has fixed size graphical area.It contains one or more images.Every image can be animated by placing them in animation frames.
Every part of GIF file is a frame.All such frames make the complete graphical area or logical screen.

- Every file starts with a fixed length header.

- Every logical area consists of an image, the extension block and the trailer that is referred as the last byte of the file. Source: CoolInterview.com
Question: What are the benefits & limitations of GIF89a Animations?

Answer: Transparency, Compression , Interlacing, various colors palettes are applied
