Reproduction or distribution is prohibited. • Conceptualized in 2007/08 • Applied first draft in October 2009 • Classification : USPC 703/1 – Computer Aided Design, and more specifically to modeling environments and objects. • Motivation: – Ability to model one or more shape(s) in a combination of methods. Thus sharing parts of a surface. – Real-time rendering without loss of modeling caps Patent Info

Reproduction or distribution is prohibited. • Each has its benefits depending on usage and field. • In CAD both are used in a form of either/or where the end result is one of the object types. • Viewers: transform everything to triangles. – GPUs are powerful enough, and getting more powerful – Maintain 60 fps by hiding objects while moving Which is better?

Reproduction or distribution is prohibited. • Cylinder Definition: – Radius, height, transformation matrix – 1000 triangles – 10000 triangles – Boolean Operation of a larger cylinder cut by two planes. – Extrusion of a curve (defining a circle) – Etc… • Resulting shape is the same • Huge difference in capability and footprint. Example of definitions

The information in this presentation is Confidential and Proprietary to Computers & Communication Technology (CCT). Reproduction or distribution is prohibited. • A semi merge of both forms. • Preserve the properties inherited by objects • Preserve the solid rules locally (if applicable) • Reduce un-important parts • Dynamic rendering; change in representation as needed. Our Approach General

The information in this presentation is Confidential and Proprietary to Computers & Communication Technology (CCT). Reproduction or distribution is prohibited. • Divide a complex object to shells • Depending on shell feature importance, one of the definition is used. • Each shell can be reused in other objects. – In C0, or C1 continuity. • Each Shell/Object will have a contributing factor. Our Approach General
