Nevercenter’s Silo 1.3 is the latest subdivision-surface (sub-d) modeller to come to Mac OS X, and it’s one of the best bargains in years.
Sub-d modelling lets artists model complex, smoothly blended surfaces. The classic example is a human head: by manipulating simple polygonal shapes in Silo, you can define the complicated geometry where the nose meets the upper lip, creating perfect, smooth blends. Silo has a powerful package of polygon-editing tools, but added control over the weighting of creases isn’t available, and there’s no UV-mapping control.
Silo’s interface is fast, efficient and customizable. Smart tools let you work on half-models with symmetric mirroring; you can quickly join faces on separate objects and blend shapes into single surfaces. Silo 1.3 lets you draw directly on sub-d surfaces to create new geometry – a capability we’ve yet to see in more-expensive suites.
Silo is exclusively a modeller: to render, you can choose an export format and render it in another app.
As an add-on to a capable 3D environment, Silo 1.3 is a work of art.
