Output Primitives and Geometric Transformations
You learnt how some basic geometric objects such as line segments, circles, ellipses and other curves are processed for plotting on a display unit. In most of the graphics packages you will find that polygons are also used as standard output primitives. Filled polygons with single solid color (or other alternatives for filling the interior) are provided as shape primitives.
Illumination Model - Polygon rendering and ray tracing methods Theoretically illumination is exposure of a thing to the light that contributes to light reflected by an object
Question 1 How does GIS differ from traditional Maps? Explain Question 2 Explain vector data model with examples Question 3 What is spatial analysis? explain
State the technology used in LCD Some passive matrix (Pixels are illuminated in scanline order like a raster display but the lack of phospherescence causes flicker) LCDs have
What is resolution? Ans. The maximum number of points that can be shown without an overlap on a CRT is known as resolution.
Panning and zooming Components (such as your Polybounce or Animation) is simply a matter of reFrameing the world window. To pan right or left horizontally, one shifts it in the pos
Basic Tests - Producing Polygon Surface A few basic tests that must be performed before producing a polygon surface through any graphic package as: 1) All vertexes are list
This question is about linear filtering concepts using the built in filtering functions (it is not about edge detection methods). Load an MRI image and perform the following: i.
1. Modify the DDA algorithm for negative sloped lines; discuss both the cases i.e., slope > 1 and 0 Ans. For the generation of lines along with negative slopes as:
Categorization of Light resources - Point source This is the easiest model for a light emitter. Currently rays from source obey radically diverging ways from the source positi
What are the advantages of electrostatic plotters? They are faster than pen plotters and very high quality printers. Recent electrostatic plotters contain a scan-conv
