Geometry generator symbology

December traditionally is an amazing time since the weather is usually quite forgiving to long working hours.

Therefore the first parts of our recent crowdfunding project for 2.5D rendering have been merged into QGIS master and will be shipped with QGIS 2.14.

It’s something of the sort of development that we really, really, really like here at an implementation that adds enormous flexibility and enables the user to use QGIS in ways that we never thought of.

Say hello to geometry generators.

Geometry generators allow to use expression syntax to generate a geometry on the fly during the rendering process. The resulting geometry does not have to match with the original geometry type and you can add several differently modified symbol layers on top of each other.



How to use it

It couldn’t be easier to use. Open the symbology dialog. Choose geometry generator as symbol layer type. Choose what kind of symbol you would like to generate, write your expression and style it in whatever way you like.

Configuration Dialog


It’s your turn

Show the world what you can do with it.
