Examples by Tom Hasenauer of EDAG
T points
- T points allow greater control and detail in some areas of the model
- They are G2 (curvature) continuous
Use T points to reduce number of edges
Simplify surface using T points
Simplified
Star points
- Star points allow non-rectangular shapes
- 3, 5, or more faces meet in a star point
- Only G1 (tangent) continuity
Star points should not be placed near T points
- A rule is that T points and star points have to be at least 3 edges away from one another
- If not, SpeedForm will automatically extend the edge beyond the T point until the rule is fulfilled
Extended edge at T point deforms the white edge
No star point, no extension at T point – the white edge is evenly curved
Use as few star points as possible
The shape is built with 14 star points
Reflections are not smooth
Solution
Only 6 star points, in a small and fairly flat area
Improved reflections
