What is C3D?
What is C3D? C3D Geometric Kernel It offers functions for 3D solid and hybrid modeling, sketching, and 2D drawing C3D Parametric Kernel It boasts functions for creating and solving parametric constraints on 2D and 3D geometry C3D Convertion Module It reads and writes geometric models in all primary exchange formats C3D Visualization Module performs detailed visualization of geometric models and provides interaction with the interface of CAD systems 14
C3D Kernel r1 ( u 1, v 1) = p + u 1 i x + v 1 i y ; r2 ( u 2, v 2) = p + u 2 i y + v 2 i z ; r3 ( u 3, v 3) = p + u 3 i x + v 3 i z ; r4 ( u 4, v 4) = p + u 4 i x + v 4 i y + z i z ; r5 ( u 5, v 5) = p + u 5 i y + v 5 i z + x i x ; r6 ( u 6, v 6) = p + u 6 i x + v 6 i z + y i y ; 0 u 1 x , 0 v 1 y , 0 u 2 y , 0 v 2 z , 0 u 3 x , 0 v 3 z , 0 u 4 x , 0 v 4 y , 0 u 5 y , 0 v 5 z , 0 u 6 x , 0 v 6 z . Used in software products as the component responsible for geometric model construction and constructed model control 15
C3D Kernel Used in software products as the component responsible for geometric model construction and constructed model control 16
C3D Kernel Originally developed by ASCON Group, now by C3D Labs , using C++ and written in Microsoft Visual Studio 17
C3D Kernel The most known software in which C3D is typically used are ● computer aided design ( CAD ) systems ● computer-aided manufacturing ( CAM ) systems ● computer-aided engineering ( CAE ) systems 18
