3D Graphics Rendering Fog Effect Texture Mapping Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D graphics data rendering techniques require a large number of calculations and memory access operations, making it impossible for low-end devices like mobile phones and low-end desktop PCs to render 3D graphics in real time due to their limited hardware performance.
Innovation Solution
The method selectively performs or omits texture mapping based on the fog effect applied to the graphics data, using fog factor calculations to determine whether texture mapping is necessary, thereby reducing memory access operations and minimizing rendering power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If texture mapping is performed on all graphics data, then rendering quality is improved, but memory access operations and power consumption increase
Solution Approach 1:
The patent applies local quality by selectively performing texture mapping only on pixels where the fog factor indicates it is necessary. Instead of uniformly applying texture mapping to all pixels, the system evaluates each pixel's fog factor and applies texture mapping locally only where needed, thereby maintaining rendering quality in visible areas while reducing power consumption and memory access in areas where fog obscures the view
Solution Approach 2:
The patent implements partial action by performing texture mapping on only a subset of pixels rather than all pixels. By using fog factors to determine which pixels require texture mapping, the system performs the necessary texture mapping operations partially, avoiding excessive processing on pixels that will be obscured by fog, thus reducing overall power consumption and memory access operations

3Manufacturing precision
If conventional rendering techniques are used, then comprehensive rendering processing is performed, but real-time rendering is not achievable on low-end devices
Solution Approach 1:
The patent extracts and removes unnecessary rendering operations by evaluating fog factors before performing texture mapping. By taking out the redundant texture mapping operations on pixels that will be obscured by fog, the system reduces the overall processing load and increases rendering speed, making real-time rendering achievable on low-end devices while maintaining completeness of rendering for visible areas
Solution Approach 2:
The system performs partial rendering processing by selectively applying texture mapping only where necessary based on fog factors. This partial action approach avoids excessive processing on obscured pixels, thereby increasing rendering speed and enabling real-time performance on resource-constrained devices while still maintaining comprehensive rendering quality in visible regions

AI summary
A method, medium, and system efficiently rendering 3 dimensional (3D) graphics data. The rendering method includes calculating the strength of a fog effect that is to be applied to graphics data, determining whether texture mapping must be performed on the graphics data, according to the strength of the fog effect, and performing the texture mapping according to the determination result. Accordingly, it is possible to reduce the number of memory access operations for reading textures.
