Matching the exact range is extremely important, as otherwise you can get weird bugs when you get the values outside, which will happen exceeding rarely, making them very hard to debug. Also, if the implementation really is > minimum + (maximum - minimum) * rand() / RAND_MAX; then the range is neither (min,max] nor (min,max) -- it's [min,max] _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
