WebDrawing points and lines isn't that interesting so we're going to get a little creative by using the geometry shader to draw a house for us at the location of each point. We can accomplish this by setting the output of the geometry shader to triangle_strip and draw a total of three triangles: two for the square house and one for the roof. forviamasterchargelogin
