If you are familiar with Adobe Illustrator and Photoshop, you know that vector artwork is scalable to any size, from business card to billboard, and it will look good. A raster or pixel-based image will not look good if you try to print or display it larger than it was created for.
Similarly, most 3D models are created with a level of detail appropriate for the intended output; different models for animating, higher resolution for rendering, even higher (billions of polygons) for 3D printing…
Animation:Master’s splines are very similar to Illustrator’s curves. You can create a very detailed model without a lot of polygons (actually A:M doesn’t use polygons at all). The splines connect to form a network called “patches”. Because the model is light, there is usually no need to use a proxy model when animating.
Because the geometry is spline-based, you can view it at any scale and it still looks good. It is resolution independent, so you can render it at any size. Technology continues to evolve, and what is considered high-definition today may seem low-res in a few years. However, the models that you create in Animation:Master today will still be good no matter what future display requirements might be.
