Pixar Animation Studios has launched a new cloud-based rendering service called RenderMan On Demand.

Developed in collaboration with cloud services provider GreenButton, Pixar says RenderMan On Demand offers nearly instantaneous burst rendering access to hundreds and even thousands of additional cores, enabling artists and studios to deliver the highest-quality cinematic imagery with unprecedented economy and efficiency.

The service is available now on Microsoft’s Windows Azure with Linux availability following later in 2012. The initial phase of RenderMan On Demand is targeted at small- to medium-sized studios using Microsoft Windows. Over the next two years, RenderMan On Demand will be expanded into a comprehensive solution for users of all levels and studios of all sizes.
