Abstract
A method and apparatus of a device for obtaining a geometric representation of an object including a thin structure having a first surface and a second surface; generating one or more 2D blocking faces as a simplified representation of one of the first surface or the second surface; generating one or more 3D blocks based on an extrusion of the one or more 2D blocking faces; and determining a 3D mesh of the object based on the one or more 3D blocks.
Claims16
A non-transitory machine-readable medium having executable instructions to cause one or more processing units to perform a method comprising:
- obtaining a geometric representation of an object including a thin structure having a first surface and a second surface;
- generating one or more 2D blocking faces as a simplified representation of one of the first surface or the second surface;
- generating one or more 3D blocks based on an extrusion of the one or more 2D blocking faces;
- and
- determining a 3D mesh of the object based on the one or more 3D blocks.
A computer implemented method comprising:
- obtaining a geometric representation of an object;
- determining a surface of the object as a thin surface indicating the object including a thin structure based on the geometric representation of the object, wherein the thin surface is adjacent to a first surface and a second surface of the thin structure, the first surface and the second surface being larger in size than the thin surface;
- identifying one of the first surface or the second surface of the thin structure as a source surface for an extrusion;
- determining one or more 2D blocking faces as a simplified representation of the source surface;
- performing the extrusion from the one or more 2D blocking faces toward another one of the first surface or the second surface, wherein a 3D representation of the object is established based on the extrusion of the one or more 2D blocking faces;
- and
- generating a 3D mesh based on the 3D representation of the object.
A system comprising:
- a memory storing instructions;
- one or more processors coupled to the memory, the one or more processors executing the instructions from the memory to perform a method comprising:
- obtaining a geometric representation of an object, the geometric representation including a narrow surface, a first surface and a second surface for a thin structure of the object and wherein the narrow surface being adjacent to the first surface and the second surface;
- generating at least one blocking face as a simplified representation of the first surface;
- generating a volume block based on an extrusion from the at least one blocking face towards the second surface;
- and
- generating a 3D mesh for the object based on the volume block.
