A class for drawing cones

int radius_coord

The coordinate that will be the radius of the cones.

virtual DVobject* copy()

We also want a routine that returns a pointer to a copy of the object created with new

DVcones( const float x0=0.0, const float y0=0.0, const float z0=0.0, const float x1=1.0, const float y1=0.0, const float z1=0.0, const float r1=1.0, const float r2=1.0 )

A simple cone, with two extremities and two radius values given. The line between the two points is the center line of the cone. By default it is a cylinder of radius 1.0, starting at the origin, parallel to the x-axis and of length one.

DVcones(LCVMarray_2D<float> &coords)

The coordinates of the points for one string of cones are stored in the array coords. A cone will be drawn (see the description above) between each point in the string and the next one.

DVcones(LCVMarray_3D<float> &coords)

The coordinates of the points for several strings of cones are in the array coords. The strings may not have the same length. Each string of cones is drawn as before.

DVcones& set_data(LCVMarray_2D<float> &coords)
