qgis - Creating DEM from LAS file without using LAStools?



I want to create a ground model from a *.las file. The LAStools are available in QGIS but limited in use (generation of black diagonal in result file), so I can't use this.


In the GRASS tools I can find the tools v.lidar.edgedetection, v.lidar.growing and v.lidar.correction, to classify the las data. Unfortunately, v.lidar.edgedetection gives me a python error. So this isn't working either.


How could I proceed?
