Create Meshes from Height Maps using Blender

Posted May 16th, 2021 in game-development

Here's an example mesh created by the technique I'll outline in this post, from a heightmap using Blender.

Height maps are textures which represent the height of geometry as a black and white image - black means "low" and white means "high".

These heightmaps can be used in conjunction with a shading technique called tessellation, which subdivides geometry on the graphics card to increase the triangle density. A height map can then be applied to the surface to raise and lower the vertices of the generated triangles, and the result is a detailed surface.
