Computer graphics-boundary fill algorithm

  • How does boundary fill algorithm works?

    This algorithm picks a point inside an object and starts to fill until it hits the boundary of the object.
    The color of the boundary and the color that we fill should be different for this algorithm to work.
    In this algorithm, we assume that color of the boundary is same for the entire object..

  • What are the advantages of flood fill algorithm in computer graphics?

    Another real-life use of the Flood Fill algorithm is in image processing.
    It enables various image editing tasks, like color replacement, segmentation, and boundary tracing.
    For instance, it can remove or replace a specific color from an image by filling the entire region of pixels with that color..

  • What are the disadvantages of boundary fill algorithm in computer graphics?

    Boundary fill and flood fill algorithms have some disadvantage like if an inside pixel is in some other color then the fill terminates and the polygon remains unfilled.
    Boundary fill and flood fill method does not work for large polygons.
    Whereas scan line fill algorithm does not have these disadvantages..

  • What is polygon filling algorithm in computer graphics?

    This algorithm works by intersecting scanline with polygon edges and fills the polygon between pairs of intersections.
    The following steps depict how this algorithm works.
    Step 1 − Find out the Ymin and Ymax from the given polygon.
    Step 2 − ScanLine intersects with each edge of the polygon from Ymin to Ymax..

  • What is seed fill algorithm in computer graphics?

    Flood fill, also called seed fill, is a flooding algorithm that determines and alters the area connected to a given node in a multi-dimensional array with some matching attribute..

  • Which algorithm is used to fill a polygon?

    Scanline Polygon filling Algorithm
    Scanline filling is basically filling up of polygons using horizontal lines or scanlines.
    The purpose of the SLPF algorithm is to fill (color) the interior pixels of a polygon given only the vertices of the figure..

  • Why use Floodfill in graphics?

    Flood fill is an algorithm mainly used to determine a bounded area connected to a given node in a multi-dimensional array.
    It is a close resemblance to the bucket tool in paint programs..

  • In solid modeling and computer-aided design, boundary representation (often abbreviated B-rep or BREP) is a method for representing a .
    1. D shape by defining the limits of its volume.
      2. A solid is represented as a collection of connected surface elements, which define the boundary between interior and exterior points.
  • In this method, edges of the polygons are drawn.
    Then starting with some seed, any point inside the Polygon we examine the neighbouring pixels to check whether the boundary pixel is reached.
    If boundary pixels are not reached, pixels are highlighted and the process is continued until boundary pixels are reached.
  • The main advantage of scanline rendering over Z-buffering is that the number of times visible pixels are processed is kept to the absolute minimum which is always one time if no transparency effects are used—a benefit for the case of high resolution or expensive shading computations.
  • The traditional flood-fill algorithm takes three parameters: a start node, a target color, and a replacement color.
    The algorithm looks for all nodes in the array that are connected to the start node by a path of the target color and changes them to the replacement color.
Boundary fill is the algorithm used frequently in computer graphics to fill a desired color inside a closed polygon having the same boundary color for all of its sides. The most approached implementation of the algorithm is a stack-based recursive function.

Boundary Filled Algorithm: This algorithm uses the recursive method. First of all, a starting pixel called as the seed is considered. The algorithm checks boundary pixel or adjacent pixels are colored or not. If the adjacent pixel is already filled or colored then leave it, otherwise fill it.
