US Patent 11250615 3D bottom surface rendering systems and methods

Techniques are disclosed for systems and methods to provide three dimensional volume rendering of volume data for use when operating mobile structures. A three dimensional volume rendering system includes a logic device configured to communicate with a user interface and receive volume data from a volume data source. The logic device is configured to render a three dimensional representation of the volume data, generate, within the 3D representation, a two dimensional grid having several vertices, adjust vertical coordinates of the several vertices based on the volume data, and render the adjusted 2D grid as a 3D surface.
