DESCRIPTION

Sweep Patches. Generic swept surfaces consist of 2 or more curves joined end-to-end. In NURBS modelling they are called U,V pairs. The quality of surface is determined by bounding lines. Surface created by uniformly deform one curve to another. Products With Sweep Surfaces. - PowerPoint PPT Presentation

  • Sweep Patches

  • Generic swept surfaces consist of 2 or more curves joined end-to-endIn NURBS modelling they are called U,V pairs

  • Surface created by uniformly deform one curve to anotherThe quality of surface is determined by bounding lines

  • Products With Sweep SurfacesDePadova by Xavier LustMisfits sofa by ARAD RonSwingline stapler by Scott Wilson

  • Crease LinesDifferentiate sweep forms from blobsCreated by the meeting of two different planes or surfacesMay be positive or negative, but has more inherent 'integrity' than a feature linePersistent elements, dominate the form even after filletingEffective carrier of meaning and emotionThe edges where sweep patches meet in CAD

  • Voluminous FormCompare the forms in terms of Useable volume: Most of the internal space can be used to house mechanismsStance: Viewers look from the best-looking' side

  • Virtual EdgesFamily of curves add dynamism to formsThere are times when it is not possible to place curves on a product formCurves can be drawn on near flat surface as high-lights by bending the surfaceDePadova by Xavier LustDesktop audio by barouche

  • HighlightsHighlights are areas of a surface that reflect major light source to the viewerCompare with planar, cylindrical or ruled surfaces, glossy sweep surfaces produce smaller and more dynamic, flowing highlightsThe more pronounce a sweep surface is, the more complicate the highlights will be

  • The background reflection is intensified by double curvature of sweep surface

  • Edge enhancementFace-breaking

  • Voluminous FormTransfer the curve family to a 150X150X150 foam cubeThe new form should be able to house a cube 100X100X100 bigMake good use of the 25 thick zone
