FINAL PROJECT

The problem that we had with mid-term project was we needed the cells to be puffed up but they were flat. There are different ways to fix that problem. I used extrude point for each cell. But again there is a problem with that which is when you apply extrude point it becomes pointy and not smooth. In order to make them smooth I used the Wblaplace. Using this battery you can make your Object smoother. But it takes a lot of process capacity on the computer so you have to be cautious about the numbers. 

Note, just because I've changed the way that I made the model with since midterm, I have to explain in from the scratch again.

Following picture is the short form of the final Grasshopper file. In upcoming pictures and descriptions you will see different stages in the process.

For the first step I found these two pictures on the internet and I used them to shape the main object, as you can see one of them is a plan and the other is a section. We need three shapes to make an object with sweep 2, two rails and one section. Therefore, I used the plan shape for the section and the section shape for rails.

What I needed to do nest was to use Sweep 2 and make the preliminary object.

Then, I used the "Launch Box Diamond Grid" battery to create the diamond shape cells instead of having rectangular grid.

The only thing crucial here is the numbers for U and V. Again, I used pictures and real documents to make sure that it looks like the real stadium as much as possible.

Afterwards, in order to make those cells puffed up. I had to use "Extrude Point" battery. But the problem with that is I needed a point and a surface to make that happen. By this time I only have the surface, i don't have the point to extrude to it. 

In order to create those points, I used "Area" battery to create centroids, bt still, it is not enough, because it is on the surface. I needed it to be 3 inches above the surface. 

Using the Area Battery I have the centroids but it is not enough.

To move these points away from surfaces, I used the move batter but again I need a vector for the moving direction, I could not use the Z axis because cells on the side need different axis. Actually what I need was a vector that acts and a normal for each and every cell. So I  put a point in the center of the imaginary sphere that that stadium is a part of, then created a vector from the center point to each centroid.

These are the vectors that I needed

After moving the points based on the vectors, I used extrude point and then WBlaplace to make the object smoother.

this battery makes the object smooth.

Using V-ray and 3d Max I was able to make these renders, I couldn't make them any smoother, because my computer would crash every time.

In this video you can find out how every step works on a real time manner.

PROCESS

THIS PICTURE IS THE FIRST SHAPES THAT WE STARTED THE MODELLING WITH, TWO OF THEM ARE RAILS FOR SWEEP 2 AND THE OTHER ONE IS THE SECTION.    

THIS IS THE FIRST STAGE OF THE GRASSHOPPER DEFINITION, I TRIED TO ADD BATTERIES SO THEY LOOK LIKE THE REAL STADIUM BUT I HAD A PROBLEM WHICH WAS FINDING A WAY TO CHOOSE THE DIAGONAL LINES AS OPPOSED TO VERTICAL LINES, BUT AFTER TRYING DIFFERENT METHODS I USED THE KANGAROO PLUG-IN TO PICK THE DIAGONAL LINES.

IN THIS PICTURE YOU CAN SEE THE SHAPE OF THE DIAGONAL LINE BUT STILL IT IS NOT WHAT I WANTED, I NEEDED DIAGONAL LINES FOR SIDES AND VERTICAL LINES FOR THE TOP AND BOTTOM LINES.

IN THIS PICTURE DIAGONAL LINES ARE HIGHLIGHTED, ALSO AFTER ADDING "LIST ITEM" I WAS ABLE TO CHOOSE VERTICAL LINES AS WELL. 

THEN I ADDED PIPES BATTERIES TO THE OBJECTS TO THE LINES TO MAKE THEM THICKER AND LOOK LIKE THE FRAMES FOR THE LIGHTS.

 THIS IS THE RESULTS OF THE PIPE BATTERY. 

RENDERS

FOLLOWING PICTURES ARE THE PICTURES THAT I CREATED USING THE V-RAY SOFTWARE FOR RENDERINGS. 

THIS FIRST PICTURE IS THE NORTH-WEST CORNER OF THE MODEL

 THIS PICTURE IS THE VIEW FROM THE ROOF OF THE MODEL AND HOW IT LOOKS FROM CLOSE

 FOLLOWING PICTURE IS A BIRD'S EYE VIEW FOR THE STADIUM AND YOU CAN SEE ALL THE CURVES AND FACES.

ANALYSIS

THIS IS THE DEFINITION OF THE ANALYSIS, USING THE KANGAROO BATTERY I CREATED THIS ANALYSIS WHICH IS IDENTIFYING WHERE THE NORMAL OF THE FACES ARE VERTICAL AND FACE'S ANGULARITY.  

FOLLOWING PICTURE IS RELATED TO THE TOP PART OF THE MODEL AS A SMALL PORTION OF IT.

 THE FOLLOWING PICTURE SHOWS HOW THE COLORS CHANGE WHEN YOU INCREASE THE NUMBERS OF THE U AND V DEFINITION.

DOCUMENTS

THIS PICTURE IS ABOUT DETAILS AND DIMENSIONS AND I USED IT TO CREATE THE ARC.

THIS ARE THE PICTURES THAT I USED TO MAKE MY MODEL AS ACCURATE AS POSSIBLE, SPECIALLY THE TWO LAST PICTURES ARE USED AS THE PLAN AND THE SECTION.

HOW DID I DO IT?

TUTORIAL VIDEO

This is the final video in the process of making the model of the Alianz Arena Stadium in Germany in Grasshopper. In this video I explain how I made this model and I will show you different batteries and techniques that I used for this model. Final pictures and renders are in the later posts and you can see how it looks after adding the pipes and bake them in Rhino. All the renders are made in 3ds Masx and V-Ray.
