Sweep Patches

Page 2: Sweep Patches

Generic swept surfaces consist of 2 or more curves joined end-to-end

In NURBS modelling they are called U,V pairs

Page 3: Sweep Patches

Surface created by uniformly deform one curve to another

The quality of surface is determined by bounding lines

Crease Lines

Differentiate sweep forms from blobs

Created by the meeting of two different planes or surfaces

May be positive or negative, but has more inherent 'integrity' than a feature line

Persistent elements, dominate the form even after filleting

Effective carrier of meaning and emotion

The edges where sweep patches meet in CAD

Voluminous Form

Compare the forms in terms of Useable volume: Most of the internal space can be used to house

mechanisms Stance: Viewers look from the ‘best-looking' side

Virtual Edges

Family of curves add dynamism to forms There are times when it is not possible to place curves on a product form Curves can be ‘drawn’ on near flat surface as high-lights by bending the

surface

Highlights

Highlights are areas of a surface that reflect major light source to the viewer

Compare with planar, cylindrical or ruled surfaces, glossy sweep surfaces produce smaller and more dynamic, flowing highlights

The more pronounce a sweep surface is, the more complicate the highlights will be

The background reflection is intensified by double curvature of sweep surface

Voluminous Form

Transfer the curve family to a 150X150X150 foam cube The new form should be able to house a cube 100X100X100 big Make good use of the 25 thick zone
