Shadow Map is a great tool developed by the Viennese startup Shadowmap Technologies GmbH. They use 3D models of Vienna and some other cities to simulate the sun shadow at any time of the year. The use cases are different, from finding a perfect and sunny property to finding a sunny garden to enjoy a coffee.
We have developed this simple app in Unreal that allows us to upload sketches, fill them with people and 3D assets, and showcase the functionality of our solution to other stakeholders.
We call it Walk Your Sketch.
