Abstract
In a method, a visual hull is generated based on intersections of first 3D primitives of a plurality of first silhouettes with a bounding box of a 3D model. The first silhouettes are generated by projecting the 3D model onto planes perpendicular to a number of selected view directions of the 3D model. Each of the first 3D primitives is obtained by extruding a connected loop of a respective first silhouette along a view direction of the number of selected view directions that is associated with the respective first silhouette. A carved mesh is be generated based on subtractions of second 3D primitives derived from positive parts of the 3D model to carve out redundant structures from the visual hull. The positive parts are obtained based on fitting planes that slices the 3D model. A low-poly mesh sequence is generated based on progressive simplifications of the carved mesh.
