8.11.13 Tube (Pure C)

These functions draw the tube with variable radius r along the curve between points {x[i], y[i], z[i]}. The plots are drawn for each row if one of the data is the matrix. By any case the sizes of 1st dimension must be equal for all arrays x.nx=y.nx=z.nx=r.nx. String pen specifies the color and style of line and marks (see section Line styles). By default (pen=NULL) solid line with color from palette is used (see section Pallete and colors). See also Plot(). See section Tube sample, for sample code and picture.

C function: void mgl_tube_xyzr (HMGL gr, const HMDT x, const HMDT y, const HMDT z, const HMDT r, const char *pen)

C function: void mgl_tube_xyz (HMGL gr, const HMDT x, const HMDT y, const HMDT z, float r, const char *pen)

The function draws tube with radius r between points {x[i], y[i], z[i]} in 3D space.

C function: void mgl_tube_xyr (HMGL gr, const HMDT x, const HMDT y, const HMDT r, const char *pen)

C function: void mgl_tube_xy (HMGL gr, const HMDT x, const HMDT y, float r, const char *pen)

The function draws tube with radius r between points {x[i], y[i]} in plane z=Min.z.

C function: void mgl_tube_r (HMGL gr, const HMDT y, const HMDT r, const char *pen)

C function: void mgl_tube (HMGL gr, const HMDT y, float r, const char *pen)

The function draws tube with radius r between points {x[i], y[i]} in plane z=Min.z, where x[i] values are equidistantly distributed in interval [Min.x, Max.x].
