    Following an imposed in-depth study of the hybrid scenario model, and an analysis of my Double Element, I developed the concept of visual obstruction. I therefore dedicated this week to developing several test models in which the stated concept is studied, calculated (when required), and played with. The main goal was to loosely implement previously seen elements and programs of Lausanne and Paris, either based on the original scale plans, or on the developed hybrid, and Double Element, within visually obstructive planes, blocking a certain viewing angle. By doing so, I am imposing the generic viewer the requirement to observe the created space from a different angle to be able to simply see the aforementioned space.

    In this following test, the visual obstruction was calculated for only one eye (parallax was not taken into account) with a small height from the top plane of just 866[mm]. With such a low height, the size ratio between the two planes can be greatly increased (1.78x in this case). It should be added that the large ground plane could be smaller, making the obstruction more effective, but since this is a test, I decided to push the plane sizes to their maximum. The sequence of vertical planes are an increasing extrusion of a flat element from Lausanne (painted guide lines on the street). The extrusion is linear and can be summed up by defining the shortest vertical plane as n and all the other vertical planes as a multiplication of n. This linear extrusion falls in line with the concept of instancing developed during the previous week.

    The above test, albeit smaller than the previous test, proves to be more interesting in terms of obstruction as the added lateral cover allows obstruction from a second main viewing angle. This test also takes into account the parallax of having both eyes open but due to the great weight of the lateral cover, the addition of an "invisible" bottom plane was not possible and was replaced with stacked cardboard acting as a counter-weight.

    Image Sun Nov 22 2015 15:31:08 GMT+0100 (W. Europe Standard Time)Image Sun Nov 22 2015 15:31:08 GMT+0100 (W. Europe Standard Time)Image Sun Nov 22 2015 15:31:08 GMT+0100 (W. Europe Standard Time)

    This test is the most generic visual obstruction test - coverage of a plane of the same size with a slight angle (defined by the angled part of the top plane) thrown into the equation. Again, parallax is taken into account.

    This model is different from the rest. There is no "game" with obstructing larger planes with smaller planes, etc. Instead, this model is directly influenced by the Double Element - a window that focuses the view of the observer in a specific area. This time around though, the observer is looking into an inside space instead of an outside space. This creates a sort of diorama space for showcasing other models. The reason why I made this model is that it could be used to "enforce" the hidden view point of a visually obstructive element. The angle of the window can of course be modified for any viewing height, and the addition of other windows is possible and possibly required (one for the obstructed view, another for the unobstructed view). This model is therefore a container.

    My final model is a development/advancement of my parallax calculations. The extremities are curved towards the observer to greatly increase edge coverage when observing with two eyes. A vertical viewing angle is also taken into account. The horizontal bars climbing the structural column, albeit somewhat schematic, are supposed to reconstruct the facade of haussmannian apartment block of the Paris plans.


    The imposed study:

  • Week 10 - Planes - Preliminary Studies

    Par Alex O, 15/11/15

    Interests within the Double Element:

    - Dissociation/"parallisation" of two planes – based on the bed plane and window plane of Double Element (similar to the dissociation via different levels in between Lausanne and Paris).

            -- These planes are then connected via vertical braces (-> columns) – leveling of planes based on positional hierarchy             (bed, lower than window, lying down – window, standing up, higher up (eye level)).

    - There are well defined angles of the window part of the double element (25° and 65°) - angling planes within 3d space.

           -- Variable planes, instancing – planes are parallel/equal at all times but the absolute spatial position varies.


    "Make a spatial proposition for an intersection of a horizontal and vertical plane that expands the program inherent in the double element"

    Inherent program of the double element: defamiliarization of generic public space -> forcing community of viewers to look up instead of straight ahead in a city. In short; modification of the sight of the viewer.

    Expansion of such program – creation of space within the physical column that requires the viewer(s) (community of viewers) to look from another angle to see more (or "correctly" see).

    Other possibility: hidden, contradictory planes that modify generic view at certain angles.

    Inverse parallax effect: two planes become one

    Interests within the plans of Lausanne+Paris:

    (It should be noted that I have returned to my plot of origin which does not have a hybrid element as it was left alone due to "administrative" reasons. I therefore have an empty plot, as well as two columns to work with, allowing more freedom in choice.)

    Intersection of the "+" column with the facade:

    - Lausanne is a flat plane with no facade. The "+" column therefore stands on top of the street and become a structure in itself.

    - In Paris, the "+" column intersects within the building, behind the facade.

    The above "tryptic" of the three plans is a beginning of a comparitive analysis based on "weaving" the plans together. The main horizontal and vertical lines are extended to the extremities of the paper to ensure some sort of intersection with elements originating from any of the plans.

    The "weaving" of elevations is also possible - in fact, the creation of a "weaved" monge may prove beneficial in a direct analysis of horizontal and vertical elements on the XY, XZ, and YZ planes.

    Why do this? 

    "Geometry instancing is the practice of rendering multiple copies of the same mesh in a scene at once" - Wikipedia

    "A technique that combines multiple draws of the same mesh into a single draw call" - Android Developers

    The point of such an analysis is to find common recurrences, common structures, repetition of planes,"similar meshes", etc as a base, a start for my work.

  • Week 9 - Finalisation of Double Element - Bwindow

    Par yousra, Liliana, Amelie, Morgan, Alex O, 08/11/15

    Our double element was formed around a very specific concept: “look up!”. In cities, the average person looks straight – rarely up. This is due to the design of "said" cities. We decided to take advantage of a “public break”, the act of waiting for the bus, to make the user look up.

  • Week 8 - Several Modifications

    Par yousra, Liliana, Amelie, Morgan, Alex O, 01/11/15

    Changes, modifications, and more changes.


    Starting off with making the structure lighter:

    We have decided to drastically reduce the amount of wood used in the building process. The main issue was the bottom of the bed. Previously, it was a block of wood strapped together to form a generic rectangle. This was obviously not a possibility, therefore we have designed a new supporting structure which consists of 4 identical feet: these feet are similar in structural design to a small metallic roof of a bus stop. A full size, usable test was built to confirm its structural soundness. Using it like a chair did not cause any damage, in fact, the compression made the joints even stronger and ensured no lateral slipping. The feet will alternate on the structure to ensure a certain symmetry. It should be also noted that no glue, screws, or any other bonding agent was used.

    The base of the bed - 1:1 test

    Finally, we have also decided to buy flat wood surfaces to cover the large areas of the element.


    Now on to the newly implemented mechanism to ensure interesting movement within our element:
    Instead of a transformation, we decided to "force" our concept upon the user - no matter which position you angle the headrest, the window will always be above you in an optimal fashion (the external surface of the window stays parallel to the inclined surface of the bed). By doing this, we want to ensure that the user will look up through the window at the blank sky.

    An extra system was designed in Topsolid to block the side views of the user:

    Elevation - Red surface represents the system that blocks the view

    Essentially the bottom three sides of a hexagon:

    Plan of element

    Of course, this movement was drawn in three positions overlaid in the form of a plan, elevation, and frontal elevation.

    Construction details were also done to review the feasability on paper instead of on a computer:

    INFRASTRUCTURE:

    As previously stated, our element is supposed to replace one of the bus stops within the collection of hybrids.

    Within this collection, there are two bus stops. We decided to overlay them in a somewhat unorthodox manner. The plans were drawn in an axonometry with just the area of interest (the bus stops) extruded from these plans. The goal was a comparitive analysis of these two seperate areas based on the bus stops.

    Image Sun Nov 01 2015 19:11:41 GMT+0100 (W. Europe Standard Time)

    It should be noted that the hybrids do not actually conform to the actual size of the bus stop as seen on the large plan elevation of plot number 17 (they are bigger to ensure visibilty and importance of the program that is public transport).
