The Creeping Shadow On The Map


Yesterday I was actually impressed amongst the edifice shadows used in Pints inwards the Sun. Pints inwards the Lord's Day allows y'all to search for nearby pubs together with thought where the surrounding edifice shadows volition autumn during whatever fourth dimension inwards the day.

With the evolution of WebGL, dynamic map shading together with moving shadows are becoming a characteristic of many interactive maps. The novel hold off Google Maps includes edifice shadows that reverberate the fourth dimension of the twenty-four hr menses when y'all thought the map. However Google Maps is non the solely map to characteristic dynamic edifice together with terrain shadows.


OSM Buildings is a pretty awesome JavaScript library for visualizing OpenStreetMaps edifice geometry on interactive maps. Check out this Building Shadows demo to thought an event map which includes 3d buildings together with edifice shadows which are subject on the engagement together with fourth dimension of day.

The map includes 2 slide controls to arrange the put of the Sun past times the fourth dimension of twenty-four hr menses together with past times the fourth dimension of the year.


F4map is an amazing 3d map built amongst OpenStreetMap data. The map includes around incredible 3d buildings, 3d trees together with fifty-fifty the H2O is animated. The shadows on the map are inwards real-time together with reverberate the put of the Sun together with thus movement throughout the day.

My i user tip is to purpose the ctrl primal amongst the upwards together with downwards arrow keys on your keyboard to alter the angle of the map.


The Shadow Visualization Demo is around other impressive demonstration of using dynamic shadows on an interactive map. The map uses OpenStreetMap information amongst digital terrain model information from Kartverket to render a terrain map of Norway.

The map includes 2 slide controls which allows y'all to arrange the shadow positions together with lengths past times fourth dimension of twenty-four hr menses together with past times fourth dimension of year.
