Grasshopper - gmp - SOSC _ #04 - Gymnasium Grasshopper Definition Files

2010-12-03T00:54:00.007+08:00

by the chance of a parametric architecture design conference in Tongji University
i did a report of form-finding of project Shanghai Oriental Sports Center
meanwhile i sort out the grasshopper definition file of the Gymnasium basic geometry
they are formed by booleaning a serier of precisely controlled balls and tubes

here's the link of the file
mind that the files are generated by rhino 4 and grasshopper 0.6.0059
hope that it's useful to you

Grasshopper - gmp - SOSC _ #03 - Outdoor Diving Pool Roof 3D model in browser

2009-07-16T13:06:00.005+08:00

progressing the tendering drawing of facade and roof
all the work are really base on the 3-Dimension geometry
considering all the details including cladding meterial fixing, substructure, drainage system, membrane, acoustic effect, competition and landscape lighting, catwalk, maintain entrance, bracing penetration, and so on...
since the cladding meterial are decided as aluminum but not GRC, in order to lower the risk on hand of possibility, all cladding division and related details will be redone in a relative short time T_T

here presents the 3D model of Outdoor Diving Pool Roof model in browser
to be honest, this excits me so much to view real 3D objects in Flash-swf in browser!
it's not any more hard to imaging that in the future, there's no software, no harddisk
every thing are in browser in form of 3D or even 4D, which can be accessful anywhere there's a output device

Grasshopper - gmp - SOSC _ #02 - mockup

2009-06-16T14:29:00.001+08:00

first of all, the SASC – Shanghai Aquatic Sports Center was renamed by the mayor
now it is called SOSC – Shanghai Oriental Sports Center
(seems all important building or event are called “Oriental XX” in Shanghai ...)

the façade and roof 1:1 mockup of SOSC is finished
it is one corner of the last girder of natatorium
and the girders is one series of slightly changing shapes
which is generated by grasshopper
and whose surfaces are all part of developed-geometry, balls or tubes

mockup drawings

shape-finding describe of the mockup solid base for façade company

typical detail

“really huge!”
was the first word when any of us saw it first time
it’s actually 11m high

just finished - Dubai Competition_#02

2009-01-30T05:32:00.006+08:00

after half a year's running
finally we finished the Dubai Competition
from design, scripting, modeling, to rendering and layout
here's some shot of the layout
i've no idea if there will come any result for the competition it's self
opposite with more than 4000 competitor
but really
i got a lot in the progress

happY neW yeaR ! - a basic rhino script tutorial - with code & files

2009-01-05T14:17:00.007+08:00

hey every body
happy new year to all

it's a script with fuction :
"isPointInSurfaces(arrStrObject, arrPoint)"
"randRange(min, max)"
the aim is generate random position points in a certain cage made of several closed polysurfaces

here's the video tutorial:

here's the code:

Dim arrPts()

Do While i <= 2999
Randomize
arrTmpPt(xx) = randRange(0,700*100)/100
arrTmpPt(yy) = randRange(0,90*100)/100
arrTmpPt(zz) = randRange(0,1*100)/100
If isPointInSurfaces(Rhino.ObjectsByName("cage"),arrTmpPt) Then
ReDim Preserve arrPts(i)
arrPts(i) = arrTmpPt
rhino.AddPoint arrTmpPt
rhino.Print "point(" & i & ")"

i = i+1
End If
Loop
End Sub

Function isPointInSurfaces(arrStrObject, arrPoint)
Dim blnTemp:blnTemp = False
For i = 0 To UBound(arrStrObject)
If Rhino.IsPointInSurface(arrStrObject(i), arrPoint) Then
blnTemp = True
End If
Next
isPointInSurfaces = blnTemp
End Function

Function randRange(min, max)
Randomize
randRange = min+rhino.Floor(Rnd*(max-min))
End Function

Grasshopper - Rhino Scripting - Dubai competition_#01

2008-12-24T01:39:00.011+08:00

this is about another project i'm doing now
Dubai '08 - ThyssenKrupp Elevator Architecture Award
i do it with my professor of TongJi University and another friend together
the project is located in the center park of Dubai main city
and actually it's mainly a structure but not a volumed building
to make it special with others
we decide to use a special kind of structure called "Tensegrity" to transparent it
and it should collect the most amount of solar energy
at the same time avoid the wind loads and free the space as much as possible
so with these conditions, what will it look like? you will know very soon
of cause this time i'll make it in Rhino and Grasshopper to generate the whole
complicated system
but very soon i start to realize that Grasshopper can not deal
with the Multi-in-multi operations but only Multi-to-multi methods
for example, you can not generate 3 curves from 3 group of points
by only 1 grasshopper operator
but it can be easily treated as stream control in Rhino Scripting
such as "For...Next" or "Do ... Loop"
so, both Grasshopper and Rhino Scripting is necessary
Grasshopper is for visualized or geometric operations
and Rhino Scripting for Multi relationships system
like control points (big amount) position generation

anyway it's still on the way
here are some trying and progress for this project:

080804 - 080816:
still scripting in Flash, output Rhino Macros commands to modeling
getting ready to generate random position, random size, random noised shapes

081130 - 081214:
discussed a lot and the main concept principally decided
grasshopper and rhino scripting to approach the goal

and there are a lot of problem interesting issue i met
during the progress
we can talk about it later separately

Grasshopper - gmp - SASC _ #01 - introduction

2008-12-15T17:43:00.003+08:00

sorry for long time no updating the main issue
coz i'm really involved in an EXCITING real project of our office - gmp
SASC - shanghai aquatic sports center
including one gymnasium, one natatorium and one outdoor diving stadium mainly
as shown following
it's a very important and urgent project
just like the Birdnest and Watercube in Beijing for Olympic
it will be constructed and in use 2011

birds view

natatorium

gymnasium

outdoor diving pool

view to HuangPu river

in the competition stage
it is treated very free with the control cage like that

and right now
they are proposed to be built
so
every piece of surface should be developed surface
such as a part of ball or tube

firstly i operate in rhino to find the correct balls and tubes
which pass through precisely the control points

it take half a day to make all the shapes of one element
so i start to realize that the progress should be some how
recorded and progammed in a smart way
of cause
first thing come in mind is GC-generativeComponent
but let's say
i tried once with GC
it's just too boring and hard to control with lot of commands, functions
and you have to get use to the MicoStation system
so finially GrassHopper is the best choice
later on i will introduce what i've done and what i'm doing more detailly
:)

some unexpected products during work and some rhino scripting trying:

- ball series

actually they a some essential elements for boolean during my grasshopper work on a real project(later i'll introduce), quite strange, ehn?

- rhino script named Voronoi (by Gabe Smedresman 2005)

it can seprate a solid to cells according center points, actually it's a series of boolean when you run it. anyway, interesting scripting. have fun!

·大家又开始嘲笑我们国家的垃圾建筑了，这东西建在人民大会堂旁边真是有点不伦不类的，而且还花这么多钱
·老先生们把故宫的屋顶定成黄色的，真是有先见之名啊！
·经典!同意.
·干嘛要清理掉。撒点草种子，下下雨就像那种浇水后头上长草的小娃娃一样。多好看啊～～～大的绿毛龟～～～～
