Parametric Representation of Vehicle Form Based on Abstract Form Construction Principles

The constitution rule of abstract form of automobile modeling puts forward that abstract form can be dominated by two kinds of element sources: point line and block. In this study, the algorithm framework for parameterized representation of approaching vehicle shape, which is the two dominant element sources of the body, is classified. The algorithm framework for parameterized representation of approaching vehicle shape is built and run by using the built-in calculator of grasshopper platform and the third-party plug-in calculator. The shape appearance perception evaluation experiment is carried out by VR and eye tracker to evaluate the generation effect, and the generation effect is iterated repeatedly from the logical level until the generation effect reaches the expectation. Use C# language to rewrite the logic built in the trial to the encapsulated arithmetic unit, so as to achieve more efficient, high-quality and high-stability morphology generation. The form generated by the framework can be quickly transformed into automobile modeling, simplifying the design process, and improving the efficiency and quality of automobile modeling design.
