IDEA

To assist Oakley Mobile in optimising 2 highly detailed CAD Boat Engines consisting of multiple elements, down to a Virtual Reality ready model for integration into unity.

CHALLENGES

The original models consist of around 1 million polygons, the total desired number after optimisation needed to be around 100,000 polygons.

SOLUTION

Stage one was to use a process of deleting the interior parts of the engine that would never been seen as well as interior surfaces. Stage 2 involved looking at all the pipe work and recreating the complex pipes with simpler Cylinders or lathed splines again reducing the polygon dramatically. Stage 3 involved selecting all the large major part of the engine like the engine block and completely rebuilding them from scratch, modelling only the essential details and no interiors. The last stage before exporting as an FBX was to merge multiple parts of the model together to reduce the workload on the GPU when the models was imported into unity. Once the model was imported into unity textures and materials were applied to match the original supplied reference photographs.

TECHNOLOGIES USED

3DS Max, Unity, Photoshop

RESULT

The final polygon count for each model were both in the 100,000 range as desired. The models themselves can be seen on the 2 WEBGL links below the images.
