Intersection Test - Visible Surface Detection
Test: It called Intersection Test also: we go for intersection test, if Min-max test fails. Now we take each edge individually and notice if it is intersecting. For illustration, as in the figure 12 there for each edge of P1 the intersection of all edges of P2 that we determined.
Procedural Animation - Computer Animation This category of animation is utilized to produce real time animation that permits a more diverse series of actions to occur. These a
Polygon or Area Clipping Algorithm - Sutherland-Hodgman Algorithm There are different algorithms as Liang-Barsky, Line clipping, Weiler-Atherton Polygon Clipping,
What is meant by Addressability? Ans. Addressability is the number of individual dots per inch (d.p.i.) that can be formed. If the address of the current dot is (x, y) then the
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
Notes for Specular reflection (1) In addition to diffuse reflection, light sources produce highlights or bright spots termed as specular reflection. Such highlighting is extre
De Casteljau Algorithm For computation of Bézier curves an iterative algorithm known as de Casteljau algorithm is used. The algorithm uses repeated linear interpolation.
An animation demonstrates a car driving along a road that is given by a Bezier curve along with the subsequent control points: X k 0 5
What is a dot size? Dot size may be explained as the diameter of a single dot on the devices output. Dot size is also known as the Spot size.
Functions Available in Animation Packages Some broad functions available in animation packages are as: Object Function to manage and store the object database , where
Q: For the following polygon, prepare an initial sorted edge list and then make the active edge list for scan lines y = 5,20,30,35 Coordinates of the vertices are as shown in Figur
