Foto 3D CX 2 can create meshes with up to 20,000 triangles, which is enough for a very detailed model.
You can control the density of the mesh in the Wireframe Generation wizard. This is explained in the User Guide, which is located in the Help menu. See section 6.4 on page 67.
In some situations you will want a lower polygon count, while other projects will require more detail.
