Function Documentation

double UT3D_angr_el_corr ( double  aa,
double  da,
double  db 
* UT3D_angr_el_corr get angle-circ from angle of elli.
* compute point on elli from corrected angle with sin|cos * lmay|lmin
double UT3D_angr_elpt ( Point pti,
Point ptc,
Vector va,
Vector vb 
* UT3D_angr_elpt real angle for point on elli
* real angle (not angle on innerCircle. Used for dxf).
double UT3D_angr_par1_ell ( double  lpar,
CurvElli el1 
* UT3D_angr_par1_ell par 0-1 --> angle
* par1 always 0-1 (relative); if el1 is relimited to 0deg-90deg, then
* par1=0.5 gives 45deg.
* par_Angle = StartAngle + (OpeningAngle * par1)
double UT3D_par1_angr_ell ( double *  lpar,
CurvElli el1 
int UT2D_2angr_el ( double *  angs,
double *  ango,
CurvEll2C el2c 
* UT2D_2angr_el get starting- and opening angle of ellipse
* angs real-angle between major-axis and startpoint
* ango real-opening-angle between startpoint and endpoint
* CCW ?
