Frequently Asked Questions (FAQ)
What are the basics of Computer Graphics?
Computer Graphics involves creating images and animations using computers. The basics include understanding pixels, coordinate systems, and basic drawing algorithms like line and circle drawing.
What is the DDA algorithm?
The Digital Differential Analyzer (DDA) algorithm is used for rasterizing lines between two points in computer graphics. It incrementally generates points between the start and end positions.
What is Bresenham's line drawing algorithm?
Bresenham's line algorithm is a more efficient alternative to DDA, using integer calculations to determine the points of a line, which minimizes computational overhead.
How does the Midpoint Circle Drawing Algorithm work?
The Midpoint Circle Drawing Algorithm calculates the points needed to draw a circle by determining the midpoint between the current pixel and the expected circle path, optimizing for symmetry.
What is the Midpoint Ellipse Drawing Algorithm?
This algorithm extends the midpoint technique to draw ellipses, determining pixel positions by calculating the midpoint for each quadrant of the ellipse.
What are Boundary Fill and Flood Fill algorithms?
Boundary Fill and Flood Fill are algorithms used to fill closed polygons with color. Boundary Fill fills the area until it hits a boundary color, while Flood Fill fills the area starting from a seed point.
What are 2D transformations in Computer Graphics?
2D transformations involve changing the position, size, orientation, or shape of objects in a 2D plane using operations like translation, rotation, scaling, and reflection.
What are 3D transformations in Computer Graphics?
3D transformations extend 2D transformations to three dimensions, allowing for the manipulation of objects in 3D space, including translation, rotation, scaling, and projection.
