Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Constructing three-dimensional landscapes in computer-generated environments is complex and time-consuming.
Innovation Solution
An electronic device generates and updates three-dimensional landscapes by receiving two-dimensional objects and transforming their semantic representations to create a two-dimensional semantic map, which is then used to construct the three-dimensional landscape.

Engineering Contradiction Analysis
1Manufacturing precision
If traditional methods are used to construct three-dimensional landscapes, then the landscapes can be created with detailed features, but the process becomes complex and time-consuming
Solution Approach 1:
The patent uses two-dimensional semantic maps as simplified copies or representations of the three-dimensional landscape features. Instead of directly manipulating complex 3D terrain data, the system works with 2D semantic representations that capture essential landscape characteristics, thereby reducing construction time while maintaining feature detail fidelity
Solution Approach 2:
The patent introduces two-dimensional semantic maps as an intermediary representation between user input and the final three-dimensional landscape. This intermediate layer simplifies the transformation process by providing a structured, semantically-enriched 2D representation that can be efficiently converted into 3D terrain, reducing both complexity and time
2Reliability
If complex three-dimensional landscape construction methods are used, then realistic environments can be achieved, but the device complexity increases
Solution Approach 1:
The patent segments the landscape construction process into distinct stages: creating 2D semantic maps with specific features, transforming these maps into 3D representations, and then generating the final terrain. This segmentation breaks down the complex task into manageable components, reducing system complexity while maintaining realism through structured processing
Solution Approach 2:
The patent transforms the landscape from 2D semantic representation to 3D terrain by changing key parameters such as elevation, depth, and spatial distribution. By systematically modifying these parameters based on the semantic map data, the system achieves realistic environments through controlled parameter transformation rather than complex geometric modeling
3Adaptability or versatility
If dynamic updates to three-dimensional landscapes are implemented, then the environments become more adaptable, but the processing time and complexity increase
Solution Approach 1:
The patent enables dynamic landscape updates by allowing modification of the underlying 2D semantic maps, which automatically propagate changes to the 3D terrain. This dynamic approach maintains adaptability while reducing update time by working with the simpler 2D representation rather than directly modifying complex 3D geometry
Solution Approach 2:
The patent performs preliminary construction of the 3D landscape based on the 2D semantic map before final rendering or user interaction. This preliminary action prepares the terrain structure in advance, so that subsequent updates only require modifying the 2D semantic layer and regenerating affected portions, rather than reconstructing the entire 3D environment
Data Source
AI summary
Devices, methods, and graphical user interfaces are used for generating, updating, and/or presenting three-dimensional landscapes in a computer-generated environment. In some examples, an electronic device presents a three-dimensional environment. In some examples, while presenting the three-dimensional environment, the electronic device receives, via one or more input devices, a request to add one or more first two-dimensional objects to the three-dimensional environment. In some examples, in response to receiving the one or more first inputs, the electronic updates an appearance of the three-dimensional environment based on the one or more first two-dimensional objects added to the three-dimensional environment.
