These two objects are then used to create a blendshape in order to create a linear deformation from one phase to another. https://static1.squarespace.com/static/5c381c343e2d09316f384de5/t/5c84445df9619a8b1624beee/1552172125981/ Portfolio Pre-procedural planning using an interactive 3D viewer created with Unity 3D, instead of physical models. The viewer allowed physicians to discuss the anatomy, and the spatial relationships to other structures in a novel manner prior to performing the intervention. Above: test case where spatial relationships of the apex of the heart, lungs and ribs were required to determine optimal approach for valve replacement. https://static1.squarespace.com/static/5c381c343e2d09316f384de5/t/5c8362abe2c48349ec6d326f/1552110686364/ Portfolio Helix curve speaker design, sized around a Norwegian 10 cm full range driver. https://static1.squarespace.com/static/5c381c343e2d09316f384de5/t/5c835d230d9297e183b3c719/1552112648482/ Portfolio A simple cardiac anatomy App made with Unity 3D.

In 2006 the 3D Lab started utilizing rapid prototyping to aid in pre-planning of complex cases. This developed into a cardiac modeling project, which I directed, with extensive customization and project design, primarily for the device industry (used both in device training and bench top testing).

While experimenting in Rhino with the helix curve, a shape arose that looked like a ram’s horn, which brought Norse imagery to mind. With that design insight, the project quickly focused, sized around a 10cm full range driver manufactured in Norway - the speaker is just over 18 inches tall. https://static1.squarespace.com/static/5c381c343e2d09316f384de5/5c385da7c2241b0b75ec3422/5c5808bba4222f53ddf9e0a7/1552030501230/ARHansgen_067.png Personal - Hard Surface: Design The cross-section curves blend from circular to octagonal, providing a clean round edge for the driver mount, creases along the length of the horn, and a uniform flat edge at the base. Wall thickness increases as the horn narrows, adding weight and strength. The unified object centroid is minimally offset from the centroid of the driver’s magnet. https://static1.squarespace.com/static/5c381c343e2d09316f384de5/5c385da7c2241b0b75ec3422/5c57eac6652dead3278cabb2/1550210263216/ Personal -
