CAD2VIS – GAPLESS TESSELLATION
Fraunhofer IGD, Darmstadt
n CAD2Vis provides the possibility to close these gaps while tessellating
n Tolerances in CAD model may yield gaps in the tesselation
© Fraunhofer IGD
n CAD models may contain arbitrarily oriented normals
CAD2VIS – NORMALS ORIENTATION
Fraunhofer IGD, Darmstadt
n CAD2Vis provides the possibility to consistently orient these normals in a healing stage
