Returns points of an ellipse

Hi,
Dose any one know, How can i return a 3D ellipse points if i have these information about the ellipse?
All 3 length of axes, dip of each plane and azimuth of each axes.
Code:
i.e., axes length=(1 cm, 2 cm, 3cm);dip of planes=(15 deg, 80 deg);azimuth of each axes=(10 deg,50 deg, 120 deg).

I think at first i have to solve the ellipse equations and then returns it's points.
I want to use these point to plot a 3D ellipse with GMT package.

I want the plot to look like this: - points in map view (no 3D view) - color of each point should depend on its z-value. - I want to define my own color scale -... (0 Replies)

DTK_MOVE_SHAPE(3)						Draw Toolkit manual						 DTK_MOVE_SHAPE(3)

NAME
dtk_move_shape, dtk_relmove_shape, dtk_rotate_shape, dtk_relrotate_shape - shape displacement SYNOPSIS
#include <drawtk.h> void dtk_move_shape(dtk_hshape shp, float x, float y); void dtk_relmove_shape(dtk_hshape shp, float dx, float dy); void dtk_rotate_shape(dtk_hshape shp, float deg); void dtk_relrotate_shape(dtk_hshape shp, float ddeg); DESCRIPTION
These functions control the position and the rotation with which the shape shp will be next drawn. dtk_move_shape() set the translation the shape for the next draws. The position defined by x and y corresponds to the position of the ori- gin of the shape (corresponding to the point (0,0) when the shape has been created). dtk_rotate_shape() set the rotation (counter-clockwise) of the shape around its origin of the shape. This rotation is performed relatively to the initial posture of the shape (at creation time). The argument deg specify the angle of rotation expressed in degrees. dtk_relmove_shape() and dtk_relrotate_shape() do the same excepting that their arguments dx, dy and ddeg updates the current parameters of the translation and rotation. RETURN VALUE
None of these functions returns value. SEE ALSO
