3D Primitive and Composite Transformations
Previously you have studied and implemented 2D geometric transformations for object definitions in two dimensions. These transformations can be extended to 3D objects by including considerations for the z coordinate. In this unit, you will study certain methods to implement such transformations.
You must have noticed here that the translation is as simple as in 2D. Rotation however requires a little more effort in 3D. Standard rotations about three coordinate axes are simpler to perform. In order to apply rotation about an arbitrary axis, you need to have a composite transformation while scaling, shear and reflections are generalized to 3D in a natural way.
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
Q. Why are all resolutions in ratio of 4:3? The bad news is that almost every monitor can only display upto a maximum of 262,144 colours (i.e. 18 bits/pixel Colour Depth). The
Transformation for 3-D Scaling As we already seen that the scaling process is mainly utilized to change the size of an object. The scale factors find out whether the scaling i
Important points about Types of light resources - illumination model Note: While we see an opaque non-luminous object, we notice reflected light by one surface of the object
Remark for the Bresenham Line Generation Algorithm Remark: The algorithm will be properly the same if we suppose | m | Algorithm | m | (a) Input two line endi
Write short notes on active and passive transformations? In the active transformation the points x and x| show different coordinates of the similar coordinate system. Here all
Distinguish between uniform scaling and differential scaling? When the scaling factors sx and sy are assigned to the similar value, a uniform scaling is produced that maintain
