dList := glGenLists(1);
glNewList(dList, GL_COMPILE);
glBegin(GL_QUADS);
PL is an array of 15 colors

Code:=4;
glColor4ubv(@PL[Code]); //
glVertex3f(P.X, P.Y, height);
glVertex3f(P1.X, P1.Y, height);
glVertex3f(P3.X, P3.Y, height);
glVertex3f(P2.X, P2.Y, height);

Code := 5; //
glColor4ubv(@PL[Code]); //
glVertex3f(P4.X, P4.Y, height);
glVertex3f(P5.X, P5.Y, height);
glVertex3f(P6.X, P6.Y, height);
glVertex3f(P7.X, P2.8, height);

glenable(GL_BLEND);
gldisable(GL_DEPTH_TEST);
glMatrixMode(GL_PROJECTION);
glLoadIdentity;
gluPerspective(230, 1, 1, 500);

each one of these is a GL_quads with one color, the next quad im gonna plotting might, or might not be the same color.

give you a little idea what im working with, perhaps some bells will ring, http://nexrad.cjb.net

1. glNewList without glEndList is not good
2. glBegin(GL_QUADS) without glEnd() is not good
3. using gluPerspective after drawing your quads is not good
4. glEnable(GL_BLEND) and glDisable(GL_DEPTH_TEST) have no effect, either.
5. in glVertex3f(P7.X, P2.8, height); P2.8 seems to be a typo ?
6. your links leads to nowhere

yes im not a pro,

you get the basic idea tho, right?

yes i mistyped the site, http://nexrad.addwiz.cjb.net/

also my very first post shows what (part of) this code does. Also the effect im after.

really dont believe i can achieve that with masking
