11.126 Sample ‘surfa’ ¶

Function surfa is similar to surf but its transparency is determined by another data.

MGL code:

call 'prepare2d'
title 'SurfA plot':rotate 50 60:light on:alpha on:box:surfa a b

C++ code:

void smgl_surfa(mglGraph *gr)
{
	mglData a,b;	mgls_prepare2d(&a,&b);
	if(big!=3)	gr->Title("SurfA plot");
	gr->Rotate(50,60);	gr->Alpha(true);	gr->Light(true);	gr->Box();
	gr->SurfA(a,b);
}
