1. A rendering technique for generating a three dimensional (3D) weather image, the rendering technique carried out by an aircraft weather display system including a controller having a texture memory, a monitor deployed aboard the aircraft and operatively coupled to the controller, and a vertical scanning radar system operatively coupled to the controller, the rendering technique comprising: obtaining 3D weather data utilizing the vertical scanning radar system included within the aircraft weather display system; writing the 3D weather data into the texture memory as two dimensional (2D) slices; texturizing a first set of overlapping-polygons utilizing the 2D slices; texturizing additional sets of overlapping polygons utilizing the 2D slices, the additional sets of overlapping polygons intersecting and forming a plurality of different angles with the first set of overlapping polygons; and displaying the additional sets of overlapping texturized polygons with the first set of overlapping texturized polygons to produce a 3D weather image indicative of the 3D weather data.
