Introduction
As explained in [1], the design and functionalization of new materials, such as the biomaterials for instance, relies heavily on the ability of having an
accurate measure and visualization of the three-dimensional surface architectures.
Here we present a method for producing a three-dimensional surface model, obtained from the map of the brightness tones
in a microphotography.
Material
In this work, we charcaterize Acer saccharinum,
commonly known as silver maple. It is a species of maple native to eastern and central North America in the eastern United States and Canada. It is one of the most common
trees in the United States.
This Biochar was trated to high temperature in inerth Atmosphere in order to remove organical residuals.

Conclusions
Three-Dimensional rendering
From the FESEM image of a biochar sample, a three-dimensional mesh is obtained.
The data of the mesh, the vertices and faces of which are given in a .obj file, can be easily visualized by 3D software.

The results presented here demonstrate the possibility to produce three-dimensional displacement maps based on two-dimensional data.
This technique could be applied also to other fields, in particular in Biotechnology field.
