Systems and methods for automatically correcting the orientation of three-dimensional models

A three-dimensional (3D) graphics system comprising:

• one or more hardware processors configured to:
• receive a 3D model comprising a plurality of primitives distributed in a 3D space, wherein each primitive of the plurality of primitives corresponds to an original point, polygon, or mesh of the 3D model;
• determine a classification based on the plurality of primitives comprising one or more of a unique pattern, commonality, or feature that differentiates a particular object from a plurality of other objects;
• map points-of-reference associated with the classification to two or more primitives in the 3D space of the 3D model, wherein mapping the points-of-reference comprises:
• selecting a first primitive of the plurality of primitives at a position about the 3D model that corresponds to a first position of a first point-of-reference on the particular object;
• selecting a second primitive of the plurality of primitives at a different position about the 3D model that corresponds to a second position of a second point-of-reference on the particular object, wherein the first point-of-reference and the second point-of-reference on the particular object are for a first orientation vector that is used to align with a first axis of the 3D space;
• selecting a third primitive of the plurality of primitives about the 3D model that corresponds to a position of a third point-of-reference on the particular object for a second orientation vector that is used to align with a second axis of the 3D space;
• and
• selecting a fourth primitive of the plurality of primitives about the 3D model that corresponds to a position of a fourth point-of-reference on the particular object for the second orientation vector:
• generate the first orientation vector as a straight line that connects or passes through the first primitive and the second primitive of the 3D model that map to the first and second points-of-reference of the particular object;
• and
• adjust an orientation with which the 3D model is presented based on an alignment of the first orientation vector with at least the first axis of the 3D space.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a three-dimensional (3D) graphics system, cause the 3D graphics system to perform operations comprising:

• receiving a 3D model comprising a plurality of primitives distributed in a 3D space, wherein each primitive of the plurality of primitives corresponds to an original point, polygon, or mesh of the 3D model;
• determining a classification based on the plurality of primitives comprising one or more of a unique pattern, commonality, or feature that differentiates a particular object from a plurality of other objects;
• mapping points-of-reference associated with the classification to two or more primitives in the 3D space of the 3D model, wherein mapping the points-of-reference comprises:
• selecting a first primitive of the plurality of primitives at a position about the 3D model that corresponds to a first position of a first point-of-reference on the particular object;
• and
• selecting a second primitive of the plurality of primitives at a different position about the 3D model that corresponds to a second position of a second point-of-reference on the particular object, wherein the first point-of-reference and the second point-of-reference on the particular object are for a first orientation vector that is used to align with a first axis of the 3D space;
• selecting a third primitive of the plurality of primitives about the 3D model that corresponds to a position of a third point-of-reference on the particular object for a second orientation vector that is used to align with a second axis of the 3D space;

• generating the first orientation vector as a straight line connecting or passing through the first primitive and the second primitive of the 3D model that map to the first and second points-of-reference of the particular object;
• and
• adjusting an orientation with which the 3D model is presented based on an alignment of the first orientation vector with at least the first axis of the 3D space.
