How to create contour-like effects?

Hi all,

I am working on a project to simulate in-door waves propagation. I want to project the signal strength on the floor of the building and create an isohypsen-like effect; something like the following:

I am very new to jME, and I don’t have any clue on how to create such effects using jME. So, any help would be appreciated.

Thank you.

You can do the outlines with a OutlinePass, see TestOutlinePass.

As for the coloring, maybe you can do something similar to the terrain texturing, where depending on the terrain height different textures are applied, see TestTerrain.

You have to be able to produce an image that contains the signal strength at any point (x,y) on the floor, then you can apply it on the terrain as a Texture.

Thanks All. I will produce a grid of signal strengths, and then interpolate and apply the image on the floor as a texture.
