Hi I just dragged into JME to plot 3D point clouds like these in my application which is totally in Java ( using Eclipse). Could you kindly advice me whether JME is the write tool for me or I have to simply go for Java3D( old and no support)
You certainly could do those graphs using JME3. Someone more experienced than me would probably be able to recommend the best way but I can think of a couple of possibilities. (Heightmaps, deforming a plane, constructing your own geometry).
