•Morphing: object shape's transformation from one form to the other is termed as morphing that is short form of metamorphism-morphing processes can be applied to any of motion or transition including a change in shape.
• Panning: (that is: shifting of background or foreground to offer the illusion that the camera appears to follow the moving object, hence the background or foreground seems to be in motion etc.
Illustrate the Advantages of using virtual reality - it's safer (As techniques can be tried out in advance without the dangers of real operation for example maintaining a nucle
Perspective Distortion - Polygon Rendering and Ray Tracing Methods Anomalies are introduced since interpolation is performed after perspective transformation in the 3-D scree
Polygonal Meshes - Clipping and 3D Primitives Apart from polygonal surfaces, polygonal meshes are also used extensively in 3D geometric modelling.A mesh is essentially a polyg
Algorithm (scan-line): For each scan line perform from step (1) to (3). 1) For all pixels on a scan-line, arrange depth [x]=1.0 i.e. max value and Intensity [x] = background
Polygon Tables - curves and surfaces All polygons are analogous to a graph G (V, E). Remember that the analogy in which a polygon surface can be specified along with as a set
What are the various representation schemes used in three dimensional objects? Boundary representation (B-res) - explain the 3 dimensional objects as a set of surfaces that se
Rotation - 2-d and 3-d transformations Given a 2-D point P(x,y), that we want to rotate, along with respect to an arbitrary point A(h,k). Suppose P'(x'y') be the effect of ant
2D Shape Primitives You have already learnt to plot a point or a pixel on any display device. In this unit, we shall introduce you to various devices available for data input o
1. For the polygon shown in Figure on the next page, how many times will the vertex V 1 appear in the set of intersection points for the scan line passing through that point? How
xy-Shear about the Origin - 2-d and 3-d transformations Suppose an object point P(x,y) be moved to P'(x',y') as a outcome of shear transformation in both x- and y-directions a
