A forthcoming PS2 version of Gran Turismo was built using Maya, Kerris revealed. Kerris said that the Mac port is aimed at smaller professional design houses. The physics system is customizable, with different environmental rules being applied. These dynamic effects can be applied to all the elements of the 3D image - including wind direction, luminescence, gravity, and object behaviours, which can be customized by project. This also applies to moving elements of the animation, such as trees and plants, with elements such as growth rate being controllable.
Brushes can also add objects such as trees, clouds or grass to animations.
These then behave in the manner specified in the dynamic physics model. QuickTime movies Images can also be imported from other applications and QuickTime movies can be added to the piece. Maya can take a QuickTime image and use it as a reference model. In this way, a variety of moving objects can be placed within the environment, and all the elemnents of the piece will interact according to the settings made in the physics model. A designer can develop a project on a Mac, save it, and then work on it using Maya on a Windows NT workstation, for example.
