CURVY TUBE

I orginally want to try to connect two circle as a sphere; but interestingly, when I used biarc, curves were twisted

into different shapes. I kept exploding the shape and finally come up with these abstract volumes.

PIPING SPHERE

I randomly create a sphere and point clouds surrounding it. When I connected the edges and pipes them, it looked

like a bird net to me. Then I deleted pipes in the middle and left the pipes on the edge.

TWISTING TUBE

Voronoi 3D is a very interesting command that it cuts the cube into random pieces. I tried to take out some

pieces as to form different shapes of the structure.

TRIANGULAR PAVILION

When I generated the idea, I would like to create something pointed. Triangle was the first image came

up in my head. Then I tried with different combinations and angles. I was thinking the shelter should not be just a overhead blocked shelter, but a shelter that people can

still see the outside world.

TWISTING PAVILION

By creating two curves in different heights, they were lofted as a curved surface. It looked like volcano and

contour lines were created around it. After placing the pieces along the contours, it turned to be a folded wings.

CURVED SHELTER

Originally I just wanted to have one curved shelter, soon, I found that it was dull to have one. I then tried to adjust its scale and rotate it. Lastly I combined two of them and

formed a overlapping shelter.

TOPOGRAPHY TRIAL / 1

I tried to create surface between lines as to build the site topography. Then I used divide curves and obtained

points on curves. By joining the curve together, surface was created; however the process was very time

consuming and the surface was not smooth but with gaps in between. This method was a failure.

Trim the contour


I kept searching for a more direct method to generate a mesh by using the contour provided. Trim the contour line with the boundary set and I attempted to step-by-step follow the tutorial online and succesfully create a

surface mesh. This topographyof the site would be useful in the entrie project.

The size of our site was 750mx750m. As to analyze the site, there should be a point in every 1m as to create a

datascape. I thought of using the intersection of contour lines to obtain the data of each point. However, tutor

reminded me that this method might not be the most accurate method because the point were not on the same

surface and the points were not in a right order.

Projection of point

Points with different heights

Creating square grid


To produce a more accurate datascape of the site, I tried to project points to the surface by square grid. The point

would be created on top of the surface. The z value will be the height of the point which is the elevation of the

landscape.

51

Setting points in the loud area

Placing point charge

Adjust the strength of point charge according to the loudness of the area, i.e. the louder the place, the stronger the charge

Point charge affects surrounding

IMPORTANT / merge field from different points which allow them to affect other points on the same plane.

NOISINESS TRIAL / 1

As sound is spreading wave, there should be a gradual change of loudness in the atmosphere. Then I attempted to use point charge to achieve this effect. I placed several

point charge and adjusted them strength according to the loudness of the area. After merging the field, points

which were nearer to the charge would have higher value and vice versa.

Different grid size

Creating cubes according to the elevation

ELEVATION

Explaining our datascape with only numbers would be difficult for others to understand. Thus to better

represent the data, I tried to visualize it with different kind of shapes, e.g. cubes, cylinders and circles.

Considering the data within a packed grid, the difference between data was hardly observed. Thus

applying different grid size to help represent the landscape in a clearer way.

OTHER VISUALIZATION METHODS

Not all the vizualizing methods were successful to represent the data because of their shapes and

arrangement.

61

NOISINESS

As I used point charge for noisiness data, the visualization needed to be clear to show the gradient

change. I first tried to use cubes to represent the data by using thier height. It looked good in Rhino but when I

turned the view into isometric, the height difference was not obvious anymore.

MODIFICATION

Not using cubes, I turned to connect points and created nurbs. This method surprisely represented the data well.

Then I tested with different grid size to find out which size could effectively explain the data to others who

didnt know about the project.

ELEVATION

Using the projection of point, the height of each point could be obtained. As Unity needed to the data to be

from 0 to 1, I then remaped the data in the range from 0 to 1.

GRADIENT

Gradient here meant the steepness of the slope. What I did was to find the gradient of each point. I first tried to use the contours to get the points and directly evaluated the point. However, I could not get the expected result.

Then I found that actually there was tangent of point. I used the tangent coordiantes and decomposed the

points. Using the method of calulating slope (y/z), gradient of slope coulc achieve.

VISULIZATION OF VALUE MAPS

I found the isometric maps were particularly useful for our group as to transform our abstract data into an

understandable graphic.

1st version - Too literal

2nd version - The color did not create a strong constrast

3rd version - Not enough color combination

Final version of the map - Playful style suited our group

COMIC

I was doing the site introduction and our team workprocess comic.

I built a Rhino model of the site and made 2D. Then I used Illustrator to add trees, people and color to the map. Color became important here as it identified the

elements in the site and developed a style for our comic.101
