Complex Vector Graphics Implementation in Java (OpenGL, DirectX)

I need an EXTREMELY EXPERIENCED JAVA PROGRAMMER (not a PHP or Other Web Programmer) to write a highly complex vector mathematics related function for a Java class that one of my programmers has already completed. This class is one of the key components in our project and we need a highly skiller programmer to take this task with immediate effect and deliver on time. If you know your mathematics, know your OpenGL or DirectX API, have extensive experience with Vector Math in Java, this should be a piece of cake for you. I look forward to your bids. Regards, Aron
