Kavisha



I am a PhD candidate in the 3D geoinformation group of Delft University of Technology, the Netherlands. I am involved in 3D4EM project. I did my M.Tech. in Geoinformatics from Indian Institute of Remote Sensing, ISRO, India. I worked on the interoperability issues in the integration of 3D data models mainly COLLADA and CityGML . I officially do not have a surname. In my publications, I go by the name "Kavisha Kumar".
Research Interests:

  • I ♥ CityGML.
  • 3D City modelling
  • UML Modelling
  • 3D city database
  • Noise and Flood modelling in 3D
  • CityGML-InfraGML interoperability
  • Cesium webglobe

PhD pressure: Seeing triangles everywhere!

We all live under the same sky. I see triangles up there, now I know "Why"?




Recently, I made a trip to Australia, the land "Down Under", for 3DGeoinfo 2017 conference. During the whole trip, I saw "TRIANGLES" . I guess they are too much in my head now that even if I go the beach to relax (yeah, I took that photo!), I look up to the sky and all I see are "oh!! triangles.."

Just to state here, Grids are good too. I cannot explain why I don't see them or why I choose to filter them out. I just don't want to get into the argument of Grids vs TINs/Triangles. This is beyond my field of view! Hahaha..

Well, coming back to the main topic, I want to share with you all my encounter with triangles in everyday life. :) My flight was Etihad. I never really noticed that the airline logo is a TIN. It caught my eye, while I was getting paranoid about the flight duration. To be honest, it felt like a good start.


In Australia, I bought the public transport card called MyKi. Guess what, I saw another triangulation. See for yourself.



One of the sponsors of the conference was a 3D land surveying company called LARKI. Its logo is also a triangulated bird.



Another funny coincidence was with the chocolate I had. It was Toblerone. I quote, "Don't you wish all triangles were made of Toblerone?" I say, "YES!!"


Nowadays, I keep looking for triangles in the matrix. I will add more to this list, if i come across something TIN-y.
Thanks for reading the post.
