3D Model Preview System Using Partial Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for previewing 3D models in development environments do not allow users to preview pre-existing 3D models without disclosing complete content data, which can lead to unsuitable model purchases and conflicts between protecting content rights and facilitating user previews.
Innovation Solution
A computer-implemented preview system that generates representations of 3D models based on partial content data, combining these representations with user environment scenes for display, while ensuring only incomplete data is provided, and authorizing complete data access upon payment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the complete 3D model content data is provided to users for previewing, then users can accurately evaluate whether the model suits their needs, but the content rights of the 3D model provider are compromised
Solution Approach 1:
The patent creates a copy of the 3D model data that contains all visual information needed for previewing but excludes metadata and structural information necessary for actual use. This copy allows users to evaluate the model's appearance and suitability without obtaining the complete content data, thus protecting the provider's rights while enabling accurate previewing.
Solution Approach 2:
The patent extracts and removes critical metadata and structural information from the complete 3D model data before providing it to users for previewing. This extraction process retains sufficient visual information for evaluation while eliminating the components that would enable unauthorized use or duplication of the original model.
2Reliability
If the complete 3D model content data is withheld from users during preview, then content rights are protected, but users cannot accurately evaluate model suitability
Solution Approach 1:
The patent creates a specialized preview copy that contains all visual information needed for accurate evaluation while deliberately excluding metadata and structural information. This copy enables users to assess the model's appearance, geometry, and suitability for their needs without compromising content rights protection.
Solution Approach 2:
The patent applies different quality levels to different portions of the data: the preview copy provides high-quality visual information (textures, geometry visualization) while deliberately reducing or removing critical structural information (metadata, complete mesh data). This local differentiation allows accurate previewing without enabling full model reconstruction or unauthorized use.
3Reliability
If the entire scene is sent to an outside server for rendering, then content rights are protected, but processing time increases and user scene security is compromised
Solution Approach 1:
The patent segments the rendering process into two parts: user-generated scene elements remain on the user's system, while only the 3D model content data is sent to the server for rendering. This segmentation reduces the amount of data transmitted and processed by the server, decreasing processing time while still protecting content rights through controlled data access.
Solution Approach 2:
The patent introduces an intermediary preview copy of the 3D model data that serves as a mediator between the user's scene and the server rendering process. This intermediary contains sufficient information for accurate rendering but excludes proprietary metadata, enabling efficient server processing while protecting content rights and reducing transmission overhead.
4Productivity
If pre-existing 3D models are purchased without previewing, then transaction speed increases, but users may purchase unsuitable models leading to wasted resources
Solution Approach 1:
The patent enables users to perform preliminary evaluation of 3D models by providing preview copies that contain all necessary visual information. Users can assess model suitability, test integration with their scenes, and make informed decisions before purchasing, eliminating the need for post-purchase discovery and reducing wasted resources on unsuitable models.
Data Source
AI summary
A preview system previews 3D content without providing complete 3D model content data. The preview system includes at least one processor that receives a request for a 3D model for preview. The processor generates at least one representation of the 3D model based on a portion of the 3D model content data associated with the requested 3D model. The processor generates a preview scene by combining the at least one representation of the 3D model with a scene from a user image environment. The preview scene included incomplete 3D model content data. The processor outputs the preview scene for display in the user image environment.
