fastCCD_v1.0 is Released by Suejung Huh ( Ohhh! Inc. ) and Young-ju Lee (Texas State Univ), Apr 2015. ================================================= < How to Use > For the usage sample, please refer main() in main.cpp. The current implementation is only for FACE-VERTEX collisions. ================================================= < Makefile Options > 1) HANDLE_ROUNDING This is to make fastCCD to handle rounding error. We recommend to turn this option on. 2) IGNORE_EVEN This is to ignore even-number collisions. Mainly used to benchmark with exactCCD. We recommend to turn this option off. 3) _DEBUG This reports the detailed messages of each computation step. ================================================= < Detailed Information > 1) False Negatives False Negatives are the cases where CCD reports no collision for the collision case. We have not withnessed any false negatives so far in fastCCD. If found, please let us know firstname.lastname@example.org 2) Time of Contacts fastCCD generally reports the actual collision time when a collision is found. However at times, when a collision found, the actual collision time may not be correct due to rounding error. However even such case, fastCCD still detect the collision. 3) Number of Contacts In some special cases, given a found collision, the possibility of having the other collisions are ignored and only the original found collision is reported. This was our implementation choice, which can be modified based on the need of user application. Note this is not a false negative. ================================================= < BACKGROUND > fastCCD is implemented by Suejung Huh to test the practicality of the idea proposed in the paper [Reference1].
