Getting vector where mouseRay intersects the terrain

hello dudes

at first: im noob in jME … so sorry if i ask dumb questions

i know that there is a very similar topic

Getting exact point of intersection of mouse click and terrain page

but i need the exact intersection point with the terrain itself (not with its bounding) if that is possible
or is there any way to make the bound very accurate (i use a boundingBox ^^)???

thanks a lot for ur help

There is a way to do triangle-accurate picking in jME… Check this topic and the test suggested there.

Doing per-triangle intersection could be costly. You might want to try the newton search
