Add CSG to your ray tracer: Assume that your scene is built of solid "basic" objects, such as the solid interiors of spheres and ellipsoids (or even cylinders, and cubes). You can define new derived volumetric objects as the volumetric unions, differences, and intersections of these basic objects. This representation is called constructive solid geometry (CSG). You can continue recursively and define CSG objects applying set operations to other CSG objects. In full generality, a CSG object is defined by an expression tree with set operations in the interior nodes and basic objects at the leaves. One can easily ray trace a CSG object, as long one has code that computes ray intersections with the basic objects. When computing the intersection of a ray with a basic object, one stores not just the point of nearest intersection but instead computes and stores the entire interval of intersection. This interval starts where the ray enters the object and ends where the ray exits the object. To compute the ray intersection with, say, the intersection of two basic objects (each represented with its own interval), one simply compute the interval-intersections of the two input intervals. This same idea can be applied to a general CSG expression tree. (Note that a general CSG object may be non-convex and thus the intersection between a ray and a general CSG object may be composed of several intersection intervals.)
Is this still true when there are no messages in transit?
I need help with this assignment. The application will consist of a single frame that allows a user to add, edit, or delete songs from the database. Thanks.
Create a new Hash class that uses an arraylist instead of an array for the hash table. Test your implementation by rewriting (yet again) the computer terms glossary application.
What is the minimum value of p necessary to meet your goal.
Write and explain briefly three guidelines for sound policy, as stated by Bergeron and Bérubé. Are policies different from standards? In what way? Are policies different from procedures? In what way?
Suppose that we wish to partition an undirected graph into two components with the minimum number of arcs between the components. HoW, would you solve this problem?
Discuss the vulnerabilities associated with four of the ten networks described in your readings. Make sure you identify the network, potential vulnerabilities, and what the result could be from an attack against it.
Explain in your own words the power of the IF function in Excel, and indicate at least one way in which a person could utilize this function in work or personal life. Provide a rationale for your response.
(1) Compared with other younger adults, what are additional specific interface requirements expected when you design a computer interface for aging users? (2) Please provide two good interface examples solely developed for aging or senior people.
Write an application that prints the following diamond shape. Don't print any unneeded characters. (That is, don't make any character string longer than it has to be.)
Create the incident response policy which covers the development of incident response team, disaster recovery process and business continuity planning.
