3D Model Presentation with Cinematic Camera Paths and POI Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D visual design reviews are limited by static views and automatic camera movements that fail to effectively highlight points of interest, leading to audience disorientation and low engagement.
Innovation Solution
An interactive 3D presentation system that allows for the creation and sequencing of shots with predefined camera motion paths, enabling users to attach camera views to specific points of interest and adjust pacing, with a sequencer interface for arranging and playing back shots, and a search function to find relevant shots based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional automatic camera movements are used to transition between POIs, then the presentation can be generated automatically, but the audience becomes disoriented and engagement is low
Solution Approach 1:
The patent transforms static, automatic camera movements into dynamic, user-controllable camera paths. Users can interactively navigate through pre-defined cinematic shots and camera paths, allowing them to control the pace and sequence of viewing different POIs. This dynamic interaction maintains automation benefits while significantly improving audience engagement and reducing disorientation.
2Device complexity
If static views of POIs are used in presentations, then the presentation structure is simple, but the 3D quality of the model cannot be effectively conveyed
Solution Approach 1:
The patent segments the 3D model presentation into multiple cinematic shots, each focusing on specific POIs with carefully designed camera paths. Instead of a single static view or one continuous automatic tour, the presentation is divided into discrete, curatable shots that can be individually optimized to showcase different aspects of the model's 3D quality while maintaining overall structural simplicity.
Solution Approach 2:
The patent introduces cinematic camera movements and multi-angle shots to transform static 2D presentations into dynamic 3D experiences. By incorporating camera paths, panes, and tilt angles, the system conveys the true 3D quality of models through dimensional enrichment while keeping the underlying presentation structure manageable through shot-based organization.
3Ease of operation
If conventional 3D scene navigation tools are used, then users can navigate in real-time, but duplication of views from presentation to presentation is difficult
Solution Approach 1:
The patent pre-defines cinematic shots and camera paths that capture specific POIs from optimized angles and movements. These pre-configured shots ensure consistent, reproducible views across different presentations. Users can navigate real-time within these pre-defined shot frameworks, maintaining both navigational freedom and view duplication consistency.
4Adaptability or versatility
If virtual turntables are used to rotate views about the model, then the view can be rotated, but desired POIs may not be included and time is spent on low-interest areas
Solution Approach 1:
The patent applies local quality by creating specific cinematic shots that focus on individual POIs with customized camera paths, angles, and durations. Instead of uniformly rotating around the entire model, each shot is locally optimized to highlight specific features of interest. Users can selectively navigate between these targeted shots, spending time only on high-interest POIs while maintaining the versatility to view any desired location.

AI summary
An interactive 3D presentation system that utilizes a collection of shots or motion views where each shot can include a combination of a camera view and camera action. A visual transition, such as a fade, can be presented at the end and beginning of sequential shots. Between the end point of a first shot and the beginning of a sequential shot, the scene is not shown. The system allows interactive authoring and/or viewing a 3D visual experience composed by defining a collection of shots where each shot is a combination of a camera view point of interest (POI) plus a camera motion path. The POI is placed on the path in a variety of ways where it can be at the beginning, in the middle or at the end of the path. A collection of predefined, cinematically styled camera motion paths, such as a crane and track shots, can be made available to the author. The pacing and duration of each shot can be adjusted. A graphical user interface showing the scene is provided and includes thumbnails of the POI or sets of POIs where the user can select a thumbnail to play an associated shot or set. The interface allows for the arrangement and ordering of shots to be used in a presentation. The system allows a shot to be retrieved from a collection of shots by indexing the 3D locations of each shot's camera path and using this index to find the nearest neighbors to a user specified mouse cursor position. Variations in the scene can also be selected using the interface.
