NONFACTURE Posted September 26, 2009 Share Posted September 26, 2009 HI ALL Sorry to bother you, but i have a major issue. I have a Graphic which needs to be applied i.e a image onto sphere which is going to large and printed,,,, the sphere will be produced in 8 parts I have the dims and cad file per panel I have been looking for software in which I can apply the graphic onto the sphere i.e image mapping the image to the contour of the sphere and then export the file. is this possible in Vectorworks can anybody help me and advise asap as I think Vectorworks is what I need Stu Quote Link to comment
islandmon Posted September 26, 2009 Share Posted September 26, 2009 Per wikipedia: "A gore is a segment of a three-dimensional shape fabricated from a two-dimensional material.[1] The term was originally used to describe triangular shapes, but is now extended to any shape that can be used to create the third dimension." There's a kool Photoshop Plug-in called "Flexify" that maps images to segments. The problem comes with the translation to 3D. VW can map images to NURBS surface gores , but the images are distorted by the curvature. Try: 1) create the 8 image gores in PS using Flexify 2 2) export the image file for each of the 8 gores 3) Use the gore images as textures 1-8 in VW 4) Map those textures to the NURBS surfaces being careful to maintain proportionality. Getting the image > gores >map > NURBS curved surface is very challenging. Here's a quick test of the concept: Quote Link to comment
islandmon Posted September 26, 2009 Share Posted September 26, 2009 Here's an analysis of the Gores texture mapping problem showing: 1 of 8 Gores as a 2dPoly fold-out >3dPoly>NURBS textured surface. This illustration helps to clarify the NURBS mapping issue: Quote Link to comment

go2greece Posted September 27, 2009 Share Posted September 27, 2009 we do it with sketchup>export 3ds in VW > import 3ds islandmoons way is more elegant http://img19.imageshack.us/img19/3676/picture4de.png islandmoon how do you create this nurbs sphere slices? ps. the overlay function from GOOGLE EARTH would be nice in VW Quote Link to comment
islandmon Posted September 27, 2009 Share Posted September 27, 2009 islandmoon how do you create this nurbs sphere slices? Requires 3 NURBS arcs : 2@90?, 1@45? 1@ Y ( Sideview= 90? arc ) > Topview Z = 0? 1@Y ( Sideview= 90? arc )> Topview Z rotated= 45? = gore segment angle 1@ Z ( Topview )= 45?= hemisphere gore segment angle then Loft 2 rails = Y arcs with 1 profile= Z arc viola ! one gore = 45? NURBS surface Quote Link to comment
