    IntroductionThis report holds the results of four assignments as part of the course Free Form Design with the code 7M842, as lectured at theTechnical University of Eindhoven, master of Architecture, Building and Planning.

    The report accompanies an animation and the source files of the assignments.

    First a sight is selected and the program is determined. Then several shapes start resulting from manipulating basic geometrical shapesin 3D studio max. A choice is made for one shape which is then developed in detail in Rhino, a Nurbs modeling program. A constructionalanalysis in Marc Mentat is the basis for the final design which is brought to live in 3D studio max resulting in an animation.

    Assignment 1In this assignment is the objective to create a museum in Eindhoven. The museum will be about the history of Eindhoven. With anpermanent exposition hall for the history of Eindhoven where, amongst others, the influences of Philips, architects, historic events suchas the second world war will be exhibited.

    In the temporary exposition hall, a variety of exhibitions can be shown about various subjects like carnival, design and technology,depending on the time of the year, national or local events or other factors.

    Aside from that, supporting facilities will be made like a library annex auditorium, a restaurant, offices, workshop, archive and restrooms.See the table below for the measurements of these functions.

    Temporary Art Centre

    The location The building will be located at a nowdesolated site in Eindhoven near the Philipssoccer stadium. The site now holds aruined set of buildings that need to bedemolished. Afterwards more then 4000 m 2 (approximately 43m by 94 meters) will beavailable for the museum which allows fora bigger building and in addition to theabove stated functionalities a parking lot

    and a green, park like setting.

    The site is connected with the rest of thecity with the Willemstraat which leadsstraight to the city centre and to the mainroundabout around Eindhoven.

    The wormThis is a very free formed shape which houses all the functions in onebody. The form swirls around a central courtyard where the entrancecan be found from where the volume will decrease in size in eitherdirection.The wormlike shape looks like it comes crawling from the earth and isbeginning its decent ones more.

    This shape originates from one cylinder that has had an FFD 4x4x4, acouple of mesh, a melt and a bent modifiers applied to it using soft

    selections to apply them to certain areas of the cylinder as is shownin the images below.

    Choosing an alternative As the location is very organic, alternative two, the geometrical composition, has to be cut from the options. It is to big a contrast withpark like setting that has been chosen as the setting in which the museum will operate.

    With regard to functionality, both the worn and the three bodies are sufficient. The worn however excels in extravagance which willprovide a more iconic image resulting in more PR and higher visitor numbers. This is the reason why the worn has been selected as thealternative that has to be developed further.

    Assignment 2The shape has been converted into NURBS and thus is was easier to place the

    openings in the hull. The result of these operations is shown in the following 4rendered images.

    The windows along the back and the front of the shape are placed at positionswhere daylight was needed. These are the offices (ground and first floor, left of entrance), central hall (just right of entrance covering the first to third floor) andrestaurant (on the third floor in the back).

    The opening above the central hall also marks the pivoting position that this hall

    has in the overall shape and allows for an understanding of the scale of thebuilding from the inside.

    Assignment 3

    Analyzing the shape in Marc Mentat resulted in the Von Mises stressimages shown on this page. There are several areas visible that show anrelatively higher stress level and thus require attention when creatingthe construction of the building.

    The program identifies four areas:1. Top op arced body2. Accumulating forces to foundation3. Pivoting point, accumulating forces

    4. Vertical carrying forces

    Area 1 and 3 can be combined in the construction.Area 2 will result in heavier foundations.Area 4 will require constructional measures roughly equal to areas 1 and3.

    This results in the following building including materials but without interior such as vertical transportation, railings, section walls andfurniture. The shell is made of veneer wood with ruff bark as the outer lining. All other materials speak for itself.

    Assignment 4Creating the animation that was required for assignment 4 was difficult. I first tried to create an animation where the form of the buildingwas reconstructed out its original sliced cylinder. This proofed to be labour intensive as the FFD modifiers, which I used quite often, arenot possible to simulate. Those transformations had to be entered manually as editable meshes, which proofed to be too hard to do in theend (the result was unsatisfying).

    That is why I have chosen to use more then one technique in the animation. I have used parameter control and the reactor technique.The latter proofed to be too hard to calculate for my computer in the model, so I did this in a separate file, that is why this is attached asa fragment of the animation at the end of it.

    The animation tries to give the observer a 3 dimensional visualisation of the exterior and the interior of the building focussing on the

    shape of the building, its rounded appearance and the quality of the spaces it creates. In short, it shows the natural contours which theconcept of the worm invokes.

    Parameters The following parameters change in time inside the animation:

    The position of sun, as it represents the sun rising and falling. The colour of the sun, to add to the effect of a rising and falling sun. The lights inside the building go off when the sun is high enough, and are turn on again as it starts its decent.

    The duck in the pond is moving according to a path constraint on a curve (this should have had the reactor water animationtechnique), the percentage of completion was altered manually. The camera moves according to a path constraint on a curve, the percentage of completion was altered manually. The doors slide open and close at a certain point in time.

    Reactor water The creation of a realistic ripple effect in the water wasnt straight forward.

    I created a reactor water object, which is actually a spacewarp, and linked this to a plane with a water material assigned to it. I had totweak the properties of the reactor water (wave speed and length, density, etc.) the link to the plane (scale strength) and the duck(mass and friction) before I got to a satisfying result.
