Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual model coloring techniques cannot achieve a color gradient effect in a single application, limiting the realism of color application in three-dimensional models, such as human body models, where a gradual change in color is desired.
Innovation Solution
A data processing method that determines the current grid position of a touch control operation on a virtual model, collects render textures to mix historical and current colors, and updates the texture map to render a color gradient effect in real-time, allowing for continuous color application.

1Ease of operation
If a single-color brush is used for virtual model coloring, then the operation is simple and fast, but the color gradient effect cannot be achieved
Solution Approach 1:
The system pre-divides the virtual model into a grid model and pre-prepares a texture map corresponding to each grid. When coloring operations are performed, the system can directly reference these pre-prepared structures and combine them with historical rendering textures to generate gradient effects, eliminating the need for complex real-time calculations while achieving sophisticated color transitions.
Solution Approach 2:
The invention introduces a temporal dimension by incorporating historical touch control information and rendering textures from previous time points. By combining current touch position data with historical rendering data across multiple time points, the system generates color gradient effects that transition smoothly from thick to light, transforming a 2D coloring problem into a 3D spatiotemporal solution.
2Manufacturing precision
If real-time color mixing is implemented by collecting historical render textures, then color gradient effect is achieved, but the computational complexity increases
Solution Approach 1:
The system segments the virtual model into discrete grid units, with each grid having its own texture map and rendering history. This segmentation allows the system to process color mixing operations on a per-grid basis rather than globally, significantly reducing computational complexity while maintaining gradient效果的 continuity across the entire model surface.
Solution Approach 2:
The system uses rendering textures from historical time points as copies of previous color states. Instead of recalculating all color information from scratch, the system retrieves and reuses these historical rendering copies, combining them with current touch data to generate new gradient effects. This copying approach dramatically reduces computational load while preserving color realism.
3Manufacturing precision
If multiple time points are used to collect historical touch control information, then the color gradient effect is enhanced, but the time consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-dividing the model into grids and pre-generating texture maps for each grid before coloring operations begin. This pre-preparation eliminates the need for complex real-time calculations during actual coloring, allowing the system to quickly retrieve and combine historical data from multiple time points without significant time penalty.
Solution Approach 2:
The system implements self-service by automatically managing and storing rendering textures from each time point as they are generated during the coloring process. Instead of requiring external intervention or complex queries to retrieve historical data, the system maintains its own rendering history and can instantly access previous states, enabling efficient multi-time-point color mixing without additional time overhead.

AI summary
A data processing method includes obtaining, in response to a touch control operation on a virtual model, a first grid position of the touch control operation in a model grid of the virtual model at a (n+1)-th timepoint, where n≥1; determining, based on the first grid position, a first texture position of a texture map of the virtual model; obtaining information, in a render texture corresponding to the touch control operation at an n-th timepoint, of a color of a historical touch control region of the touch control operation; obtaining, a target color of the first texture position by mixing the color of the historical touch control region with a color of the first texture position; updating the color of the first texture position of the texture map as the target color; and rendering, based on the texture map as updated, the virtual model at the (n+1)-th timepoint.
