I have fixed the collision issue that I was having with the terrain. This seems to have been a pre-existing bug that I never noticed before.<\/p>\n

It took some time to track down, since some of the collision faces were working.<\/p>\n

I used gnuplot to visualise the collision list and the render list, and they both seemed to be correct:<\/p>\n

But when I plotted both the collision nodes and the renderable nodes on the same graph, I noticed that as the below images shows, the collision\u00a0list’s nodes\u00a0(in green) only contained some of the nodes that they should have.<\/p>\n

I was then able to get the collision working. For now, I am adding all nodes to the collision list, however when I implement the changes to the Level of Detail system, I will need to cull out most of the rendered nodes.<\/p>\n
