Research & Development
Weta Digital is active in both practical and foundational research and development as a means to improve the quality of our work and to stay competitive in the global market for visual effects. We believe in pursuing new and promising scientific inquiry that can provide efficiency and introduce a greater level of creativity. Our efforts include partnership with universities and other centers of research as well as other visual effects facilities. Open Source initiatives and relationships with the commercial market are both important avenues to help us to push the boundaries of what can be done. In a world where today’s innovation is tomorrow’s limitation, staying out in front is vital in an industry that thrives on creativity.
