maybe Posted November 16, 2008 Report Share Posted November 16, 2008 Hello all, Recently I have encountered another problem for 3D display. On top of all, I am using the ActiveX CwGraphic3D control. Now assuming I have 3 points: P1 (P1_x, P1_y, P1_z) P2 (P2_x, P2_y, P2_z) P3 (P3_x, P3_y, P3_z) And I know the normal: N: <N_x, Ny, Nz> If I am asked to plot the plane (rather than the triangle surface bounded by P1, P2 and P3, just a flat plan), how could I plot it on the 3D control? I saw that with 3DplotCurve and 3DplotMesh I have to give 3 vectors (x, y and z vectors); Is there a way that I can just give the normal and a point and I can draw a plan? Thanks for help.
