Probably most of you know Mr. Marners 'Evaluating Java for Game Development' report already, but anyway: http://www.rolemaker.dk/articles/evaljava/Evaluating%20Java%20for%20Game%20Development.pdf He essentially compares C++/OGL, Java/GL4Java/OGL and J3D with some (fair, as I believe) benchmarks (not full apps though). Some results from the report mostly regarding performance (as I have remebered for my own opinion :-) - unoptimized/un'tweaked' Java is around 2.5 to 4 times slower than untweaked C++ - tweaked Java is only 1.2 to 1.5 times slower than tweaked C++ - in some benchmarks tweaked Java actually was FASTER than C++ - there is enough unexploited potential in the Java HotSpot compiler to make (tweaked) Java often faster than C++ in the future - significantly reduced development cost with Java3D - Java3D is currently about 2.5 times slower than equivalent GL4Java code I personally believe, that there is more potential in Java3D itself to make it even faster, because it still is under heavy development. But don't believe me, read the report for yourself and take your own conclusions. regards Georg ___ ___ | + | |__ Georg Rehfeld Woltmanstr. 12 20097 Hamburg |_|_\ |___ [EMAIL PROTECTED] +49 (40) 23 53 27 10 PS: you might also want to read the discussion to this report at http://www.javagaming.org/Forums/forums.html, there click 'Topics', follow the link 'The Business of Java Games', then 'Odds and Ends'. =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
