3D Programming - OpenGL procedural terrain - triplanar texture mapping + normal mapping

Just a small demo of triplanar texture mapping normal mapping in action over a procedurally generated surface. To better show the effect, in this simple demo I used a brick texture over a very smooth terrain (generated using small values of “persistence“). Textures from: . .
