Rigid body or Non-Rigid body Transformations
2D transformations can be classified as rigid body or non-rigid body transformations. Rigid body transformations keep the shape and size of the objects intact whereas non-rigid body transformations do affect the shape and/or size of the object. Translation and rotation are examples of rigid body transformations. Other transformations come under non-rigid body transformations.
1. By using Digital Differential Analyzer algorithm draw line segments from point (1,1) to (9,7). Ans. We see that the usual equation of the line is specified by: y = mx+c
Viewing Transformation In previous section, we have discussed about the geometric transformations as Translation, Shearing, Reflection, Scaling and Rotation. Rotation, Reflect
For good understanding of the application of the rules specified above see the following figure, where the shaded region demonstrates the clipped polygon. Fi
Automatic Data Capture There are numerous techniques available to collect data automatically without the need for manual entry. Manual entry is slower, more costly (need to emp
y-shear about the origin - 2-d and 3-d transformations Suppose an object point P(x,y) be moved to P'(x',y') in the x-direction, through the specified scale parameter 'b'. that
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
Explain depth buffer method
Write a C-code which generates a font interactively.This means after every n mouse clicks, a Bezier curve is generated and then the terminal point of the last drawn Bezier curve is
1. If you perform a x-direction shear transformation and then a y-direction shear transformation, will the result be the same as the one which is obtained when it is simultaneous s
