Outputting

The functions in this section are are called, directly or indirectly, by Picture::output(). See Picture Reference; Outputting.

void output (void)

Virtual function

Writes the MetaPost code for drawing, filling, filldrawing, undrawing, unfilling, or unfilldrawing the Solid to out_stream.

void suppress_output (void)

Virtual function

Used in Picture::output(). Sets do_output to false, if the Solid cannot be projected using a particular set of arguments to Picture::output().

void unsuppress_output (void)

Virtual function

Used in Picture::output(). Resets do_output to true, so that the Solid will be tested for projectability again, if the Picture it's on is output again.

vector<Shape*> extract (const Focus& f, const unsigned short proj, real factor)

Virtual function

Tests whether all of the Shapes belonging to the Solid are projectable, using the arguments passed to output(). If it is, this function returns a vector of pointers to Shape containing a single pointer to the Solid. If not, an empty vector is returned.

bool set_extremes (void)

Virtual function

Sets projective_extremes to contain the maximum and minimum values for the x, y, and z-coordinates of the Points on the Shape. Used for determining projectability of a Solid using a particular set of arguments.

const valarray<real> get_extremes (void)

const inline virtual function

Returns projective_extremes.

real get_minimum_z (void)	const virtual functions
real get_maximum_z (void)
real get_mean_z (void)

Returns the minimum, maximum, or mean z-value, respectively, of the Points belonging to the Solid. Used for surface hiding. See Surface Hiding.
