Gouraud Shading
The faceted appearance of a Lambert shaded model is due to each polygon having only a single colour. To avoid this effect, it is necessary to vary the colour across a polygon :
In order to achieve this, the colour must be calculated for each pixel instead of one colour for the entire polygon. By ensuring that the method we use to calculate the colour results in the neighbouring pixels across the border between two polygons end up with approximately the same colours, we will be able to blend the shades of the two polygons and avoid the sudden discontinuity at the border. Lambert shading is based upon calculating a single normal vector for the surface (which is then compared to the lighting vector and the viewpoint vector to determine the colour). Gouraud shading is based upon calculating a vertex normal rather than a surface normal. A vertex normal is an artificial construct (a true normal cannot exist for a point such as a Visual Realism vertex). A vertex normal can be thought of as the average of the normals of all the polygons that share that vertex.
In the amortized analysis, the time needed to perform a set of operations is the average of all operations performed. Amortized analysis considers as a long sequence of operations
In this unit, we will describe a data structure called Graph. Actually, graph is a general tree along no parent-child relationship. In computer science, Graphs have several applica
A connected graph is a graph wherein path exists among every pair of vertices. A strongly connected graph is a directed graph wherein every pair of distinct vertices is connecte
QUESTION Explain the following data structures: (a) List (b) Stack (c) Queues Note : your explanation should consist of the definition, operations and examples.
Acyclic Graphs In a directed graph a path is said to form a cycle is there exists a path (A,B,C,.....P) such that A = P. A graph is called acyclic graph if there is no cycle in
