RENDERING, SHADING AND COLOURING
By introducing hidden line removal we have already taken one step away from wire-frame drawings towards being able to realistically model and display 3-D objects. Perhaps the biggest step down that road comes when attempting to "colour in" our simple line drawings. The various algorithms for rendering, the process of applying lighting, colouring, shadow and texture to an object or scene in order to obtain a realistic image, are all based to a greater or lesser extent on the study of the physical properties of light. In this unit we shall examine various properties of light and the way it interacts with objects and develop some simple mathematical models of its behaviour. It is worth setting the following discussion in the context of our system as developed so far. Currently our 3d model is made up of surfaces, each of which we represent on the screen by drawing its outline. If we wanted to shade each polygon ("colour it in") what color would we use? What we basically are trying to achieve in this chapter is to derive a method for calculating that colour. Figure 3.16 shows the difference between a wire-frame representation and a simple rendered version
Q. Explain the technique to calculate the address of an element in an array. A 25 × 4 matrix array DATA is stored in memory in 'row-major order'. If base address is 200 and
what is boot algorithm and some example
Task If quicksort is so quick, why bother with anything else? If bubble sort is so bad, why even mention it? For that matter, why are there so many sorting algorithms? Your
The two famous methods for traversing are:- a) Depth first traversal b) Breadth first
The below formula is used to calculate n: n = (x * x)/ (1 - x). Value x = 0 is used to stop the algorithm. Calculation is repeated using values of x until value x = 0 is input. The
A queue is a, FIFO (First In First Out) list.
This algorithm inputs number of hours of sunshine recorded every day for a week (7 days). Output is the highest value for hours of sunshine and average (mean) value for numbers of
Surrounding of sub division method A polygon surrounds a viewport if it completely encloses or covers the viewport. This happens if none of its sides cuts any edge of the viewp
Q. Describe what do you understand by the term array? How does an array vary from an ordinary variable? How are the arrays represented in the specific memory?
It is a useful tool for indicating the logical properties of data type. It is a collection of values & a set of operations on those values. Methodically, "a TYPE is a set, & elemen
