Frequently asked questions: Explain rotation transformation and transition transformation. What is clipping?  Briefly explain about DDA line drawing algorithm, with an example. Explain the Cohen-Sutherland line clipping algorithm. Explain 3D Transformation? Programming based questions: Answers: 1.)  DDA line drawing algorithm Digital Differential Analyzer (DDA):  is an algorithm,  for the simple line generation.  And it is used for  interpolation of variables over an interval between the start and end point.  Such as rasterization of lines, triangles, and polygons. This method can be implemented using floating-point or integer arithmetic.

Purpose We explore the soil to know it's detailed information of soil and also for groundwater conditions such as : Engineering properties of soil and it's nature or nature of the formation. Locations of groundwater, their condition, and variation. Sometimes for survey purpose, to check the soil properties of various locations. Methods:
