Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The interoperability of 3D digital assets among studios or different pipeline versions is difficult and labor-intensive, requiring manual re-modeling and re-texturing, which is costly and time-consuming, and often results in inaccuracies due to the intense reliance on human participation.

Innovation Solution

An image processing system that automates the conversion of high complexity 3D digital models into a pipeline-agnostic format by using virtual cameras to generate renders, UV texture coordinate spaces, and transfer lighting and non-lighting information, including ambient occlusion and normal vectors, to create a flexible and scalable model representation.

2Adaptability or versatility

If manual re-modeling and re-shading is used to convert 3D digital assets, then asset interoperability is achieved, but the process is prone to inaccuracies and deviations from original art direction

Engineering Contradiction:

Improveasset compatibility across pipelinesVSAvoidaccuracy of asset representation

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The automated conversion process creates an accurate digital copy of the original asset by systematically capturing and transferring geometry, materials, and lighting data, preserving the original art direction without human interpretation errors

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent implements feedback mechanisms where the converted asset is compared against the original to ensure accuracy, allowing for verification and correction of any deviations from the source material

Inventive Principle:

Principle #23Feedback

3Manufacturing precision

If proprietary renderer engines and custom pipelines are used to produce final renders, then visual quality and artistic control are improved, but interoperability between different studios and pipeline versions deteriorates

Engineering Contradiction:

Improvevisual quality of rendered assetsVSAvoidcompatibility with other studios and platforms

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal conversion system that can handle assets from different proprietary pipelines and render engines, making them compatible with multiple target platforms while preserving the visual quality achieved in the original pipeline

Inventive Principle:

AI summary

An image processing system includes a computing platform having processing hardware, a display, and a system memory storing a software code. The processing hardware is configured to execute the software code to receive a three-dimensional (3D) digital model, surround the 3D digital model with multiple virtual cameras oriented toward the 3D digital model, and generate, using the virtual cameras, a multiple renders of the 3D digital model. The processing hardware is further configured to execute the software code to generate a UV texture coordinate space for a surface projection of the 3D digital model, and to transfer, using the multiple renders, lighting color values for each of multiple surface portions of the 3D digital model to the UV texture coordinate space.
