They are efficient and well suited to solve rotation and orientation problems in computer graphics and animation. This paper describes two new methods for splining quaternions so that they can be used within a keyframe animation system. We also show that quaternions, although up to now solely ...
Input and Output Functions of a Computer The input computer function accepts data from input devices and sends it to the computer processor, while the output function communicates the results of processing. A class of hardware devices known as peripherals are used to perform these functions. Common...

Such a markup denotes the document function, and it could be interpreted as reverse video on a computer screen, underlining by a typewriter, or italics in typeset text. SGML is used to specify DTDs (document type definitions). A DTD defines a kind of document, such as a report, by ...
You can see an example in the fileembed/main.go. The example defines several new functions which can be called by BASIC: PEEK POKE PLOT SAVE CIRCLE When the script runs it does some BASIC variable manipulation and it also creates a PNG file - thePLOTfunction allows your script to set a...
The styles available in MathType are Text, Function, Variable, Lower-case Greek, Upper-case Greek, Symbol, Vector-Matrix, Number, and Extra Math. MathType also has User 1 and User 2 styles. It will assign certain styles to certain kinds of characters automatically, based on its knowledge ...
Note that should anIF-THEN-ELSEstmt be used in aTHENcode block or multipleIF-THEN-ELSEstatements are used in either a singleTHENorELSEcode block, the block grouping is ambiguous and logical processing may not function as expected. There is no ambiguity when singleIF-THEN-ELSEstatements are pla...
