http://archive3d.net/ http://www.3dmodelfree.com/ http://tf3dm.com/ http://www.creativecrash.com/ https://clara.io https://3dwarehouse.sketchup.com/ http://www.thepixellab.net/freebies http://3dsky.org/ There are some free 3D models on  http://www.cgtrader.com/ , like this detailed microscope: Available here:  http://www.cgtrader.com/free-3d-models/science-medical/lab-equipment/microscope--6 And of course  http://www.turbosquid.com/ , if you look hard enough you might find some surprisingly good 3d models amongst the lower quality stuff.

Some Qt and C++ tickles for UNISA COS2614

Some simple things to remember for the UNISA COS2614 exam, in no particular order: Download Qt here:  https://www.qt.io/download/ Nice simple Qt examples here:   http://zetcode.com/gui/qt4/ Nice Qt videos here:   https://youtu.be/6KtOzh0StTc?list=PL2D1942A4688E9D63 C++ if-else shorthand (ternary operators):   condition ? value_if_true : value_if_false Command Line Arguments:   int main ( int argc, char *argv[] ) The integer, argc is the ARGument Count (hence argc).

The array of character pointers is the listing of all the arguments. argv[0] is the name of the program, or an empty string if the name is not available. After that, every element number less than argc is a command line argument. You can use each argv element just like a string, or use argv as a two dimensional array. argv[argc] is a null pointer.
