FAQ
HFZ to GLTF Conversion
What are HFZ files?
HFZ is the compressed version of the HF2 terrain height map format, in which the whole file is packed with the gzip method. A height map is a rectangular grid where every cell holds the elevation of one spot of a landscape, and such grids can grow very large when they cover wide areas in fine detail. HFZ keeps them small by combining two ideas: heights are stored as differences between neighboring cells, and the author chooses how precise the heights need to be. The same data can also be found with the .hf2.gz extension. In a published comparison, a terrain saved as HFZ took about 1.4 MB, while the same terrain in the TER format packed with gzip took 1.8 MB, at equal vertical precision.
What are GLTF files?
glTF or GL Transmission Format is a vector extension developed by the non-profit consortium Khronos with the aim of improving interoperability between various types of software specialized in creating and accessing 3D content. The extension is compatible with several application programming interfaces (APIs) that offer 2D and 3D vector graphics rendering, including WebGL, OpenGL ES and OpenGL.
