2-d and 3-d transformationspreviously we have presented approaches for the generation of polygonal regions and lines we identified that once the
important points for windowing transformations1 window explains what is to be viewed and viewpoint describes where it is to be displayed2 frequently
windowing transformations - raster graphics and clippingfrom the above section of introduction we understood the meaning of the viewport and term
cases of the sutherland hodgman polygon clipping algorithmin order to clip polygon edges against a window edge we move from vertex vi to the
sutherland-hodgman algorithmany polygon of any type of arbitrary shape can be explained with the assist of some set of vertices connected with it
polygon clipping - raster graphics and clippingafter considerate the idea of line clipping and its algorithms we can currently extend the idea of
cases of clip a line segment-pqcase 1 as we determine a new value of te that is value of parameter t for any potentially entering pe point we select
a convex polygonal region having n- vertices p0 p1 p2 pn - 1 pn p0 or lattice points to be identified by the user includes the convex window area to
limitations of cohen sutherland line clipping algorithmthe algorithm is merely applicable to rectangular windows and not to the other convex shaped
geometrical examine types of line clippinggeometrical examine of the above kinds of clipping it assists to get point of intersection of line pq along
trivial acceptance case of cohen sutherland line clippingscase 1 it is trivial acceptance case whether the udlr bit codes of the end points p q of a
line clipping algorithm - cohen sutherland algorithmline is a series of endless number of points here no two points contain space in among them hence
point clipping - 2-d viewing and clippingpoint clipping is the method related to suitable display of points in the scene though this type of clipping
objectives of 2-d viewing and clippingafter going through this section you should be capable to1 describe the concept of clipping2 observe how line
polygon or area clipping algorithm - sutherland-hodgman algorithmthere are different algorithms as liang-barsky line clipping weiler-atherton polygon
2-d viewing and clipping - raster graphics and clippingin the previous two units of this block we illustrated the basic elements of computer
1 distinguish among scan line polygon fill and seed fill or flood fill algorithmscan line polygonflood fill algorithms1 this algorithm
1 do we have need of to generate the full circumference of the circle utilizing the algorithm or can we can produces it in a quadrant or
1 compare bresenham line generation with digital differential analyzer line generationans bresenham line generation algorithm is better than
1 by using digital differential analyzer algorithm draw line segments from point 11 to 97ans we see that the usual equation of the line is specified
1 how does the resolution of a system influence graphic displayans in a high resolution system the adjacent pixels are so near spaced such
1 what is the purpose behind the staircase effectans the approximation concerned in the calculation for finding of pixel position concerned in the
1 what do you understood by the term graphic primitivesans graphic primitives are the basic graphic objects that can be united in any number and
summary of graphic primitivesin this all section we have illustrated the basic graphic primitives that are line point and circle we have also
polygon filling algorithm - raster graphics and clippingin several graphics displays this becomes essential to differentiate between different
