Recently has been stuck in one place, more than a week now,
Made a java3d, mouse and keyboard in linkage is something wrong with the above, I want to make "mouse, keyboard will continue movement according to the direction of the mouse after the rotation, but I my application results after rotating object is the mouse, keyboard and press down will return to its original position,
Feeling should be the object using the above make a mistake, but where is the specific error is can't find,
Now is to achieve the object related to place my card for a long time, there is multithreaded, mysql, redis, file operations, high concurrency, all want to use on the project, the graduation design all don't know when will it be ready, before the end of may be on June 10th will reply, I good food!!!
Why use java3d anything so old, I wrote a feeling: https://liu-endong.blog.csdn.net/article/details/104854301
