that the HPC increases from being 2.2 times faster than the Mac Pro to 3.3 times faster than it by removing the breaking foam on the waves from the animation. This identifies a need for a more optimised code for the HPC to run wave animation within Blender.

Table 5 Render process times for computers benchmarked (without foam in the animation)
By reducing the animated ocean size to 250 square metres, with a simple plane extending to the horizon the rendering time was further reduced to around 28 minutes on the HPC with a rendered output of 1920x1080 pixels. This optimisation of animation render setup reduces the overall time by
over 80%, these are critical considerations in the design workflow.
With many of today’s software programs incorporating their own distributed rendering systems to allow multiple users within a work environment to utilize the other machines for rendering it would appear that an office equipped with around 10 high end dual
The benefits of this technology do not only stop at visual representation as with the use of real-time ray tracing and live 3D stereo viewing, it enables users to fully interact with their environment and to ergonomically resolve the design in ways that are currently difficult to simulate without building full scale mock ups. An example of this is in boat and engine maintenance which in small craft can prove to be exceptionally challenging, due to the confined spaces required to work with.

workstations linked to a central server machine could effectively and cost efficiently produce high quality animations overnight and at weekends with minimal initial outlay.
9. THE FUTURE
With technology ever increasing what is the future going to hold for this industry? One of the most revolutionary developments
has been in the area of GPU based
rendering that utilizes CUDA technology [7] in order to use graphics card accelerated rendering. CUDA based graphics cards such as the new Nvidia Quadro 6000 [8] can utilize up to 448 cores to render with which although slower than a conventional CPU it means that the sheer number of them makes computational time a lot quicker and has enabled the creation of 3d Real Time Ray tracing in programs such as V-ray RT [9] which allow the user to walk around and manipulate the rendered scene in the same manner that they would navigate around a 3D model.
The uses for this technology are great because a single workstation utilizing up to four of these graphics cards could produce real time 3D images in front on the screen. Couple this with the recently released 3d monitors and glasses or recently developed depth cameras as used in Microsoft’s Kinect products and it enables designers and possible customers to virtually interact with a product on a whole new level. The great possibilities include fully customizing a product such as a boat interior with the client within a matter of hours [10].
