Study On Application For Landform In Landscape Architecture Planning And Design Based On Rhino And Grasshopper Parametric Technique

With the rapid development of landscape architecture industry,connotation and extension are enlarging continuously.Planning and design requires more assistant techniques to help complete its scientificalness.The design for geodetic landscape is one of the important subject studies to landscape architecture planning and design.In the initial period,it requires series of relative scientific analysis to the site so as to provide scientific suggestions for all kinds of green space planning and design.Landform is still the base of landscape architecture.This is directly related to the environment factors and morphological feature and influences natural biological systems of the site.To make use of landform and allocate landform scientifically require specific scientific status.It is especially important to scientifically and effectively analyze landform during the process of landscape architecture design.At the present stage,the survey to the present site for relief analysis is the initial work to landscape architecture planning and design.The data of assistant software to be used is complicated and difficult to obtain.The whole process lasts long and needs lots of labour.There exists differences which is lack of scientific and objective pursuance between the analysed result and actual situation.Serving as an entry point,this research aims to scientifically and effectively analyze landform with Rhino and Grasshopper parametric technology assistant technical platform and find out the measures and models to landform analysis which is suitable for landscape architecture planning and design.Rhino and Grasshopper parametric technology is a technology with three dimensional visualization which has great ability of building up models,utilizing logic to make up of administration and analyzing huge status,to meet analysis requirements to different types of landscape architecture planning and design and scientifically analyze the landform of project with the help of status base of digital landform construction and by getting DEM status to build up landform models and by making up system by the logic of Grasshopper.According to the utility advantage of the study object and paratrised techology,the writer has chosen the parametrised techiqual platform of combining Rhino and Grasshopper and defined the main content,measures,technological route and innovation point.With study and survey,the writer has summarised the steps and measures for obtaining DEM data and building up relief model and expressed the principles and logical structure for Rhino and Grasshopper paratrised technology on relieves,elevations,contour lines,slope,aspects,sunshine,surface rain runoffs and visible zones and summersized the expression function to all kinds of relief analysis result.The writer has chosen Huicheng Forest Park as empirical study and guidiance to entire design to furtherly proove the practicalility and precise scientificalness by using the parametrised technology of Rhino and Grasshopper to analyse the relief and finally expressed that this techology can greatly help designers obtain relief data and present direct and clear 3D visible resutl to relief and more satisfy the demand to present desgin,strongly push the development of landscape architecture industry.With this chance,the writer hopes to dialectically and objectively study relief with a newer assistant technique and logic thinking so as to provide new ideas for landscape design in the new era and arouse more people's attention,study and discussion to parametric technology.
