Reducing 3D CAD data is a necessary step to insure your interactive experience runs fast and smooth. Usually CAD data comes with hundreds of thousands of polygons that your interactive application can’t handle. Reducing 3D CAD data especially helps when you are visualizing many 3D models in virtual or augmented reality. The simulation or experience might only need to see the outside shell of a model and not any internal parts. Typically we are able get a 60% – 99% model reduction per 3D object.
Why do we reduce 3D CAD data?
Reducing 3D data makes your interactive experience run smooth and on as many devices as possible. Getting your message in front of as many people as possible. These optimized 3D models are streamlined for real-time visualization and can be used on the web, in augmented reality or virtual reality; on mobile phones and tablets.
How we reduce 3D models.
Rebuilding from a model from scratch is one of the best ways to reduce 3D data. We start by using existing 2D or 3D CAD data, drawings, photos, or sketches. Roughing the forms out using primitive geometry and modifying them until the model matches the original aesthetically. Another method is Decimating your model in a 3D package. This will reduce the polygon count of your models in a very efficient way while keeping all their sculpted details. This solution is one of the fastest available and is able to optimize your high polycount models. At Photonic we use 3D software such as ZBrush, Maya, and 3DSMAX to prepare models for real-time environments, such as, websites, mobile phones, touchscreen devices and virtual or augmented mixed reality headsets.
