Project Neon is a rendering service that offers greater productivity and a faster turnaround of photorealistic renderings by leveraging the power and compute capabilities of the cloud. Rendering is a time and hardware intensive process that translates 3D models into photorealistic images that allow the design team to optimize the results they deliver to their clients. By harnessing the power of the cloud, customers no longer you have to wait for long periods of time to generate single or multiple views of their designs, The Project Neon service eliminates the need for customers to purchase and maintain expensive hardware for their rendering needs. Providing a realistic view into designs during the entire design process delivers superior results for your customers.
