Exploration Summary

#1

Investigate the point cloud machine as a methodology to record 3D objects.

#2

Point cloud presents big amount of data yet with low clarity because of the abscence of information between points.

#3

Understand the production logic of the curve wall by the horizontal and vertical sections produced from the data.

the noted corner in Innovation Tower is the key site of this project.

It is a inward slanted concrete wall located near one of the exit on ground floor.

Stage 1:

Data Extraction

Projection from 3D to 2D

We selected hemp rope because it is The initial idea was to extrude lines not elastic. The rope was curvy so from the curve wall to a flat sur- we tried to wet them with water in face. We first create a 10x10 grid on order to straighten the strings. the concrete wall by tape. The grid’s boundary could be refered to the original casting marks on the wall which is a big rectangle.

Strings are attached to each intersection in the grid. By gravity, they pointed downward to the tracing paper on floor.

We tried to tie pens with the string in order to record the point. The weight distribution on the pen is not centered and wind is affect the marking so it failed.

From this stage, we started to investigate the extrution of 3D object as a way to collect data. Yet there are logic errors. The grid is not fixing on the wall accurately and stably since we cannot damage the surface of the concrete. We further thought about having the two side of the grid system in harder material since the vertical section of the wall is constant.

We decided to extrude the wall horizontally with an external device.

It avoids the problem of inaccurancy of the grid but then we need to build the device having all extrusion sticks parallel to the ground since we cannot make use of the gravity.

The prototype is built. The wood stick turns out loose and we need to design extra tools to tighten all sticks during measurement.

The device must to parallel to one of the flat side of the wall. Extra wood became our guidance.

Stage 2:

Measuring Tool Refinement

According to our plan, we would like to insert all loose stick into the device firstly.

By pushing all sticks to wall, the contour of the wall shld come out and we would fix the sticks and do marking. However, the sticks keep shifting when we do marking since its so loose. We decided to unload all sticks and tighten them one by one.

We tried to fix the sticks from bottom to top and reformed the curve on our device as shown in photo.

Reflection The final product functioned well.

Yet there are rooms to be improved.

Firstly, there could be mechanism to tighten and loosen the wood stick.

In this exploration, we are using extra material to fix the stick.

This is a one way process meaning the tightening material will be destroyed when we pull them out. If there are more systemetic tightening mechanism, we can recreate the measured data without the wall.

Secondly, the measuring target size is limited to the surface area of the tool. It would be more practical if the measuring limit is adjustable.

Reflection By the data collected, we saw the horizontal sections varies a lot while the vertical sections only showed slight changes. By this, we could see Zaha Hadid architects design this corner mainly through plan view. The slight changes in vertical section could be defects that occured during concrete casting.

Stage 4:

Recreate through Rhinocernos

After attending the Rhino courses, we found similarities between the software and real life measurement.

Pointcloud is a function of Rhino which faciliate multitude visualization of large scale irregular surface. It works same as the machine we designed which is to communicate 3D in big amount of data but with low efficiency. All information between points will be lost. This reflect the problem behind our design.

STAGE 5:

Tools development

We try to have a further development in our first design to become a very useful tool in future which can help the constructor to build a big scale curve by a mini curve adjustment tools or using our mesurement tools to extract the data of a big scale building structure.

STAGE 6:

Summarize the data into tool

For the experience last time , we try to summarize ours data to become a tool instead of the detail drawing.

FINAL STAGE PRESENTATION

At the final stage presentation, we have a 5 minutes to present our project since first stage, after that the other group will show the product built according to our drawing set. With this kind of interaction, we clearly understood the mistake of the drawing when the other group showed the outcome and criticized our drawing set.

This part of the course is fun and works better than tutors banning ideas without the students realizing where the problem really is.

In our case, we found the connection is far more complicated than expectation especially when the product is in larger scale. The drawing may work if it is in a scaled model. Yet, to communicate with contractor, it requires careful thinking and drawing to avoid unnecessary mistake.

Drawing Set

To exchange drawing set and make other group’s model.
