LOW-POLY MESH GENERATION FOR THREE-DIMENSIONAL MODELS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18517914 titled 'LOW-POLY MESH GENERATION FOR THREE-DIMENSIONAL MODELS

Simplified Explanation

The abstract describes a method for generating a visual hull based on intersections of 3D primitives of silhouettes with a bounding box of a 3D model, followed by carving out redundant structures and generating a low-poly mesh sequence.

  • Generation of visual hull:
 - First silhouettes are generated by projecting the 3D model onto planes perpendicular to selected view directions.
 - First 3D primitives are obtained by extruding connected loops of the silhouettes along associated view directions.
  • Carving out redundant structures:
 - Carved mesh is generated by subtracting second 3D primitives from positive parts of the 3D model.
 - Positive parts are obtained by fitting planes that slice the 3D model.
  • Generation of low-poly mesh sequence:
 - Progressive simplifications of the carved mesh result in the generation of a low-poly mesh sequence.

Original Abstract Submitted

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.
