3D printing and mechanical simulations are two situations which require solid modelling, that is, a representation of 3D objects which clearly distinguishes the parts of an objects which are filled with solid material and the parts which are filled…

After implementing an intuitive one-finger 3D translation gesture which kept landmarks under the user’s finger as the camera moved, we wanted a similarly-intuitive gesture for 3D camera rotation. We ended up replicating the style of camera…

In a mobile application we are developing, we display a 3D world through which users need to navigate quickly in order to perform tasks at different geographic locations. Our first camera implementation for this app was simple: translate one-finger…

At Spiria, we are currently migrating our repositories from svn to git. In the process, we have encountered a surprisingly large number of small issues, which I would like to share with you today. If you are planning to undergo a similar migration…

Installing Haskell on Ubuntu seems to be a challenge. But maybe I can help!
