+
+With the toolbox at disposition we just need to configure the \
+BeeSampling to render images on a regular 3D grid.
+
+.. literalinclude:: examples/blenddemo_beesampling.py
+ :lines: 13,16-23
+
+If we want to use the distance to objects, we need to tell the \
+BeeSampling what is the maximum distance to objects in the environment.\
+ Otherwise the distance can go until infinity, and since the image are \
+compressed in the database, all distances to object will be equal to \
+zero:
