System and method for optimal geometry configuration based on parts exclusion
System and method are provided for building and rendering a 3D graphics dataset of an object that consists of multiple parts, wherein the 3D graphics dataset includes a 3D geometry dataset and a configuration file, and in the configuration file each of the multiple parts is identified as used (e.g., visible, actionable) or unused (e.g., not visible, not actionable) in each of multiple display features (e.g., in display states, such as in animations, or in display relationships). The method determines which of the multiple parts are unused in each of the multiple display features and identifies those parts, which are unused in all of the display features, as excluded parts, and saves a list of the identified excluded parts in association with the object. In rendering the object on a display, the method does not load data directed to the excluded parts, to thereby speed up the loading/rendering process.
1. A computer-implemented system comprising a processor, a memory, and a display, wherein:
the memory is configured to be loaded with 3D graphics data of an object that consists of multiple parts, wherein the 3D graphics data includes a 3D geometry dataset and a configuration file, and in the configuration file each of the multiple parts is user-specified as used or unused in each of multiple display features; and
the processor, when loaded with computer-executable instructions, executes an algorithm including:
(i) determining which of the multiple parts are user-specified as unused in each of the multiple display features;
(ii) determining those parts that are user-specified as unused in all of the multiple display features as excluded parts, while determining those parts that are user-specified as used in at least one of the multiple display features as non-excluded parts;
(iii) saving a list of the excluded parts in association with the object; and
(iv) in rendering the object on the display, loading only 3D geometry data of the non-excluded parts independently of animation key frames that depict the non-excluded parts, while not loading 3D geometry data of the excluded parts, wherein not loading the 3D geometry data of the excluded parts is different from not loading animation key frames in which the excluded parts are not visible.
2. The system according to claim 1 , wherein the configuration file defines processing of the 3D geometry dataset, and (iii) includes saving the list of the excluded parts in the configuration file.
3. The system according to claim 1 , wherein a part user-specified as used in a display feature is a part user-specified as visible in the display feature, while a part user-specified as unused in a display feature is a part user-specified as not visible in the display feature.
4. The system according to claim 1 , wherein a part user-specified as used in a display feature is a part that is user-specified as actionable in the display feature, while a part user-specified as unused in a display feature is a part user-specified as not actionable in the display feature.
5. The system according to claim 1 , wherein each of the multiple display features defines a display state in which the object is rendered on the display, or a display relationship according to which the multiple parts of the object are rendered on the display.
6. The system according to claim 5 , wherein the multiple display features includes an animation feature, which is a display feature defining a display state, and a constraint feature, which is a display feature defining a display relationship.
7. The system according to claim 1 , wherein the algorithm further includes, prior to (i), providing a UI indication on the display that (i)-(iv) will be executed.
8. The system according to claim 1 , wherein (iv) further includes not loading metadata of the excluded parts.
9. A computer-implemented method comprising:
(i) loading, to a memory device, 3D graphics data of an object that consists of multiple parts, wherein the 3D graphics data includes a 3D geometry dataset and a configuration file, and in the configuration file each of the multiple parts is user-specified as used or unused in each of multiple display features;
(ii) determining which of the multiple parts are user-specified as unused in each of the multiple display features;
(iii) determining those parts that are user-specified as unused in all of the multiple display features as excluded parts, while determining those parts that are user-specified as used in at least one of the multiple display features as non-excluded parts;
(iv) saving a list of the excluded parts in association with the object; and
(v) in rendering the object on a display, loading only 3D geometry data of the non-excluded parts independently of animation key frames that depict the non-excluded parts, while not loading 3D geometry data of the excluded parts, wherein not loading the 3D geometry data of the excluded parts is different from not loading animation key frames in which the excluded parts are not visible.
10. The method according to claim 9 , wherein (iv) includes saving the list of the excluded parts in the configuration file.
11. The method according to claim 9 , wherein a part user-specified as used in a display feature is a part that is user-specified as visible or actionable in the display feature, while a part user-specified as unused in a display feature is a part user-specified as not visible or not actionable in the display feature.
12. The method according to claim 9 , wherein each of the multiple display features defines a display state in which the object is rendered on the display, or a display relationship according to which the multiple parts of the object are rendered on the display.
13. The method according to claim 9 , wherein (v) includes not loading metadata of the excluded parts.
14. A non-transitory computer-readable storage medium whose contents configure a computing system to perform a method, the method comprising:
(i) loading, to a memory device, 3D graphics data of first and second objects that share at least one common part, wherein the first object includes at least one first part unique to the first object and the second object includes at least one second part unique to the second object, wherein the 3D graphics data includes a 3D geometry dataset for the first and second objects;
(ii) generating a first list of excluded parts for the first object, by determining which parts are user-specified as unused in each of multiple display features for the first object and by identifying those parts that are user-specified as unused in all of the multiple display features for the first object as first excluded parts;
(iii) generating a second list of excluded parts for the second object, by determining which parts are user-specified as unused in each of multiple display features for the second object and by identifying those parts that are user-specified as unused in all of the multiple display features for the second object as second excluded parts;
(iv) in rendering the first object on a display, loading only 3D geometry data of non-excluded parts of the first object independently of animation key frames that depict the non-excluded parts of the first object, while not loading 3D geometry data of the first excluded parts, wherein not loading the 3D geometry data of the first excluded parts is different from not loading animation key frames in which the first excluded parts are not visible; and
(v) in rendering the second object on the display, loading only 3D geometry data of non-excluded parts of the second object independently of animation key frames that depict the non-excluded parts of the second object, while not loading 3D geometry data of the second excluded parts, wherein not loading the 3D geometry data of the second excluded parts is different from not loading animation key frames in which the second excluded parts are not visible.
15. The medium according to claim 14 , wherein (iv) includes loading only metadata of the non-excluded parts of the first object while not loading metadata of the first excluded parts, and (v) includes loading only metadata of the non-excluded parts of the second object while not loading metadata of the second excluded parts.
