List out the various Text clipping?
All-or-none string clipping -if all of the string is inside a clip window, keep it or else discards. All-or-none character clipping - discard only those characters that are not completely inside the window. Any character that either overlaps or is outside a window boundary is clipped. . Individual characters - if an individual character overlaps a clip window boundary, clip off the parts of the character that are outside the window.

Polygon Rendering and Ray Tracing Methods In previous section we had discussed various methods for visible-surface detection, although in order to produce visibility the prese
Define B-Spline curve? A B-Spline curve is a set of piecewise (usually cubic) polynomial segments that pass close to a set of control points. Though the curve does not pass by
What are the advantages of rendering polygons by scan line method? i. The max and min values of the scan were simply found. ii. The intersection of scan lines with edges i
Implement Cohen Sutherland and Liang Barsky line clipping algorithms in C-language. Test your code for line segments with end points falling in various regions.
Distinguish between uniform scaling and differential scaling? When the scaling factors sx and sy are assigned to the similar value, a uniform scaling is produced that maintain
Objects - polygon rendering and ray tracing methods Objects could be any state of material as solid, liquid. Gas and plasma. Though ray tracers can merely assist objects whic
Polygon representation methods - Boundary representations Boundary representations: now the 3-D object is shown as a set of surfaces which separate the object interior from
Limitations of Cohen Sutherland line clipping Algorithm The algorithm is merely applicable to rectangular windows and not to the other convex shaped window. Consequently, a
In contrast to depth-buffer method, here we identify one surface at one time, scan-line method deals along with multiple surfaces. Since it processes each scan-line at one time, al
