Modelling, Seeing, Imagining & Photography

I believe that to understand a model we need to experience it, feel it even if it is in some very different way…. The more we experiment the more we can imagine and this is probably our way of modelling what we don’t know through our life inputs or the data we collect. Photography is all about the experimentation and imagination that make us build imaginary portraits that we materialize through a shot. My first photo experiment that I place here was the bokeh effect.

Round and creamy a mixture of color that gives a yummy taste on the nightly environment full of color and sparkling lights. Why are night shots so captivating that we forget everything around us?

Continuing my divagation through chair design and analysing the previous chair/seat post.

The purpose of this design is to serve as a support for objects. All 4 legs are tilted in a square fashion pattern at the bottom and are closer to each other near the table surface.

It’s not my intention to replicate the design of the table completely so my first simplification is the junction of the legs to the table.

Every design has it’s strengths and weaknesses. It’s purpose and function. This design is particularly sensitive to edge force since leg is supporting the table center. For a table this size the table will work comfortably with the objects we place on top, however as a seat considering an average weight of 80Kg.

So here starts the challenge:

  • Withstand 80 Kg to 120Kg
  • Use a clean, light design

Everyone probably already has an idea and the first one that comes up my mind is a straight leg chair (the simplest form of this design).

So why do we bother inventing new ideas??? The answer is that not all people are made equal. Some like simple chairs, others like edge design chairs, some others are in between and the rest probably don’t care.

Looking for over the edge designs, challenge our notion of possible or not possible. And maybe let us feel in some way better either for simplicity or because of blending in room design…

Why NetGen Why!!

This time around I am presenting a alternative mesher to gmsh. The application is called NGSolve/NetGen it’s installable both in Mac and Windows which made me very happy at the beginning. Afterwards I opened a step file with no issues and generated a default mesh (on the windows version).

I really liked the visual display and the mesh quality. This is a default mesh.

The close up rendering mesh shows good image detail and the mesh elements geometry look more uniform and the circular shape looks well represented through the mesh.

At a first view the mesh seems much better compared to gmsh. There is however a problem. I could not open step and iges files through my mac. This was a frustration…. It seems that the windows version already has a binary file for open cascade which is the library that allows the NetGen software to understand these formats. On the other hand there is no easy way to install the open cascade library on a mac neither it seems to have been tested in detail with netgen.

This is a big frustration point for me.
