Polygon -Rendering Methods
Now we will see the application of an illumination model to execute the rendering of standard graphics objects that are formed along with polygonal surfaces. Scan line algorithm classically applies lighting model to carry out rendering of polygon surfaces, through using any one of the two techniques:
1) All polygons can be rendered along with a single intensity.
2) The intensity can be acquired at each point of the surface utilizing an interpolation scheme.
Functioning of Input Devices Functioning of input devices-Keyboard, mouse, trackball and space ball, Joystick, data glove, digitizer, scanner, touch panel, light pen, voice sys
Important Points About the Diffuse Reflection An extremely rough surface appears uniformly bright from each viewing direction Q the intensity of reflected light is identical i
Shearing - 2-D and 3-D transformations Shearing transformations are utilized for altering the shapes of 2 or 3-D objects. The consequence of a shear transformation seems like
