Animation and Games - CAD and CAM
In our childhood, we all have seen that the flip books of cricketers that came free with some soft drink and where some pictures of similar person in diverse batting or bowling actions are sequentially arranged in separate pages, so when we flip the pages of the book the picture shows to be in motion. It was a flipbook several papers of the similar size along with an individual drawing on all papers so the viewer could flip by them. This is an easy application of the basic principle of physics termed as persistence of vision. Such low tech animation was fairly popular in the 1800 year while the persistence of vision that is 1/16th of a second was discovered. This discovery led to several more interesting low tech animation devices as the zoetrope, wheel of life, etc. Later, depending on many basic mathematics and physics principles, some researches were conducted that allowed us to produces 2d/3d animations. In this section we will study the transformations implicated in computer graphics but you will see that all transformations are associated to space and not to time. At this time lies the basic dissimilarity between graphics and animation. The dissimilarity is that animation adds to graphics the dimension of time that vastly raises the amount of information to be transmitted
Animation, Video and Digital Movies : These are sequences of bitmapped graphic scenes or frames, quickly played back. But animations can also be made inside the authoring system t
Perspective Projections - Transformation In this projection the center of projection is at limited distance. This projection is termed as perspective projection since in this
Light Sources - polygon rendering and ray tracing methods Light Sources are key parts in any ray traced scene, since without them; there would be no rays to trace. Light sour
Advantages of Scan line Algorithm: This time and always we are working along with one-dimensional array as: x[0...x_max] for color not a 2D-array like in Z-buffer algorithm.
types of character generation techniques
Put the system of a geometric data table for a 3d rectangle. Solution : Vertex Table Edge Table Polygon Surface Table
Photo and Video were determined in the 19th century: In books Visuals as add on to texts. They enabled distance education. They developed learning where verbal description was n
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 do you mean by Perspective projection? Perspective projection is one in which the lines of projection are not parallel. Instead, they all converge at a single point known
What is orthographic oblique projection? When the direction of the projection is not normal (not perpendicular) to the view plane then the projection is called as oblique proj
