11.44 Sample ‘dens_xyz’ ¶

Functions densz, densy, densx draw density plot on plane perpendicular to corresponding axis. One of possible application is drawing projections of 3D field.

MGL code:

call 'prepare3d'
title 'Dens[XYZ] sample':rotate 50 60:box
densx {sum c 'x'} '' -1:densy {sum c 'y'} '' 1:densz {sum c 'z'} '' -1

C++ code:

void smgl_dens_xyz(mglGraph *gr)
{
	mglData c;	mgls_prepare3d(&c);
	if(big!=3)	gr->Title("Dens[XYZ] sample");
	gr->Rotate(50,60);	gr->Box();	gr->DensX(c.Sum("x"),0,-1);
	gr->DensY(c.Sum("y"),0,1);		gr->DensZ(c.Sum("z"),0,-1);
}
