Our goal to provide creators of 3D worlds with a set of tools to easily reflect the complexity of reality fits DS’s vision perfectly,” says Sébastien Deguy, CEO and founder, Allegorithmic. “Our tools are designed to enable artists to drive the production process, based on mathematical principles. There is a clear fit with 3DVIA’s broad target audience.”
