Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a particle system is used to simulate visual special effects, then various effects such as fire, explosion, smoke, and water flow can be achieved, but a realistic trailing visual effect cannot be obtained
Solution Approach 1:
The patent changes the parameters of the particle system by introducing an extending trajectory parameter that defines the path along which particles are generated and distributed. This parameter modification enables the particle system to produce trailing visual effects while maintaining realistic appearance, resolving the contradiction between realism and trailing capability.
2Reliability
If three-dimension computer graphics technology is used to render virtual space, then realistic visual presentation is achieved, but trailing visual effects cannot be generated
Solution Approach 1:
The patent segments the trailing effect generation process into distinct components: acquiring an extending trajectory, generating particles along the trajectory, rendering particle primitive models, and combining these elements. This segmentation makes it easier to implement trailing effects within the three-dimension graphics rendering pipeline while maintaining visual realism.
3Adaptability or versatility
If existing particle system methods are applied, then various natural phenomena can be simulated, but trailing effects with realistic appearance cannot be produced
Solution Approach 1:
The patent enhances the universality of the particle system by making it multi-functional: it can now produce both traditional natural phenomena effects (fire, smoke, water flow) and trailing visual effects with realistic appearance. The extending trajectory parameter allows the same particle system to adapt to different effect types while maintaining realism, resolving the contradiction between versatility and trailing effect quality.
