Introduced first in SolidGeometry 2.4, Creation date: 2015-08-08, Last change: 2025-09-14
returns a convex solid for a transformed vertex list
Description
Useful state of the art function to move/rotate a base contour first, the create a convex delaunay solid, a returns it with index lists for the individual surfaces (uses SGofVLdelaunay).
Translation support: dz, t-vector, 3x3 matrix, 3x4, 4x4 matrices
Example Illustration
Syntax
[SG,ViL,FiL,FNL,FoL]=SGofVLtrans(VL,T,[TS,comp])
Input Parameter
VL: | | Vertex list (nx3) or (nx2) |
T: | | required translation; if scalar the t==>t=[0 0 t]; |
TS: | | transformation of the solid afterwards; default is []; |
comp: | | compensates the contraction for phi-x or phi-y; default is false |
Output Parameter
SG: | | Solid geoemtry |
ViL: | | Vertex index list for the surface |
FiL: | | Facet index list for the base and tranformed contour |
FNL: | | facet normal list for the base and transformed contour |
FoL: | | Facet index list for the outside shell of the solid |
Examples
SGofVLtrans(PLcircle(10,4),[rotdeg(0,0,45),[0 ;0 ;40]]) % rotz-45 and t=40
SGofVLtrans(PLcircle(10,4),-30); % z=-30
