Subdivision modeling: When is good enough, good enough? The cylinder on the left has 20 segments. The cylinder in the middle has 64 segments. The cylinder on the right has 12 segments. So why can't the geometry on the left hold its shape when subdivision smoothing is applied? [Arguably] one of the most common answers to…
Subdivision modeling: mesh density Vs loop structure on curved surfaces. Sharpening corner details by adding support loops that interrupt the segment spacing of a curved surface will generally result in some kind of smoothing artifact. The example below demonstrates how adding the highlighted support loops to the existing…
Subdivision modeling: use more geometry or create better geometry? Removing subdivision smoothing errors from shape intersections on curved surfaces is a common theme for questions about hard surface subdivision modeling. A lot of these questions are about pinching and stretching issues near corners and around shape…
