Displacement mapping is an alternative computer graphics technique in contrast to bump, normal, and parallax mapping, using a texture or height map to cause an effect where the actual geometric position of points over the textured surface are displaced, often along the local surface normal, according to the value the texture function evaluates to at each point on the surface.

A heightmap created with Terragen The same heightmap converted to a 3D mesh and rendered with Anim8or. In computer graphics, a heightmap or heightfield is a raster image used mainly as Discrete Global Grid in secondary elevation modeling. Each pixel stores values, such as surface elevation data, for display in 3D computer graphics.

A slicer is a toolpath generation software used in 3D printing.It facilitates the conversion of a 3D object model to specific instructions for the printer. The slicer converts a model in STL (stereolithography) format into printer commands in G-code format.
Look up the height in the heightmap that corresponds to the position on the surface. Calculate the surface normal of the heightmap, typically using the finite difference method. Combine the surface normal from step two with the true ("geometric") surface normal so that the combined normal points in a new direction.
Supports unlimited terrain size using custom data swapping mechanism to hard disk space. Terrain made of multiple terrain zones supporting variable resolution and automatic border stitching. Procedural heightmap generation using fractal, terracing and erosion tools. Possibility to create and assign multiple layers of heightmaps for each zone.

STL is a file format native to the stereolithography CAD software created by 3D Systems. [3] [4] [5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography, [6] although it is also referred to as standard triangle language or standard tessellation language.
