Google Cardboard and OpenStreetMap

Here is what open street map data looks like when viewed through Google Cardboard. This was recorded on my iPhone 5S (ancient technology I know!). It is a block of data around Glasgow. The keen eyed of you may recognise the Glasgow City Chambers building at around 25 seconds in. You should be able to… Continue reading Google Cardboard and OpenStreetMap

Now that we have the walls complete, I thought it would be a good time to move onto rendering the rooftops! Instead of having to triangulate the polygons myself, I looked online to find a triangular to do it for me. I stumbled across an old flipcode article that had a triangular in it. I simply… Continue reading Rendering Rooftops – Triangulating polygons

Progressing Forwards At the end of the previous post I had processed the Openstreet map data - created polygon data for each building and then drawn these buildings using the GL_LINE primitives to give us a wireframe outline for the building as shown below: To take this to the next stage - the next task was to draw… Continue reading Rendering solid walls

I hope the creator (Rob Rawks) doesn't mind! The main steps that… Continue reading Rendering Building Corners with Open Street Map

City Rendering with OSM

Rendering Cities using OSM So lately I was feeling like getting back into messing around with some 3D "stuff". I recently came across Vizicities and was inspired to do something similar myself. The basic Idea is to render a city (in this case) using open source data from Open Street Map. One of the reasons I… Continue reading City Rendering with OSM
