I decided to see if i can write an algorithm to print out the fibonacci sequence in Java. I got really frustrated because it was something so simple, and used the debugger to ...
I'm currently looking for a Java Mesh Library. If my understanding is correct, this would be something similar to OpenMesh. All I've found at moment is JMesh 'A Polygonal Mesh Library in Java' (http://jmesh.origo.ethz.ch/) which is still in development. Context : turning a very large stl file into a Mesh structure (probably winged- or...

The problem is that, since the points of the polygon were randomly generated, some of the polygon are overlap with other polygon. How can I avoid this, so that every po...
I used to think that each memory location contains 8, 16, 32 or 64 bits. So 0101 would be stored in an 8 bit machine as 00000101 (sign extended if it was negative). This was all fine and dandy until I wrote a program in java out of curiosity to find out some more inner workings of this system. The method in question looks like this: p...
