Applied the new bedrock system to surface rock types (visible on mountains/cliffs). It's not super realistic, but I guess it looks interesting enough?

Water is temporary ofc, just to give some idea. I don't have actual water implemented yet 😅

And ofc stuff like forests, biomes, etc will happen, but not right now.

Btw, the main island is ~50km in length.

I should've guessed this is plural!

That's one silly model that has interesting cell-like things emerging. The model is essentially just point particles of N different kinds, interacting via randomly-generated forces. The crucial thing is that forces are asymmetric (e.g. A attracts B, B repels A), violating Newton's 3rd law, but allowing for a lot of moving an generally non-trivial behaviours.

However, an std::array<int, N> with no initializer doesn't actually initialize the ints - it performs default initialization, which is a no-op for primitive types, so the whole std::array initialization is also a no-op.

_________________________

Afaik there's no way to do it directly during construction (apart from explicitly writing {5,5,5,...,5}). Technically std::array doesn't have any constructors, thus it is an aggregate type.

There's a way to do it with a variadic template function that effectively generates this {5,5,5,...,5} initializer using variadic unpacking, see https://stackoverflow.com/a/57757301/2315602

std::array has just the method you need: https://en.cppreference.com/w/cpp/container/array/fill

A more old-school way would be std::fill with begin/end iterators to the array: https://en.cppreference.com/w/cpp/algorithm/fill

A more modern version of this is std::ranges::fill that doesn't need iterators: https://en.cppreference.com/w/cpp/algorithm/ranges/fill

Split a single large terrain mesh into small chunks (to support terrain modification, frustum culling, etc), optimizing the mesh generation & data on the way (triangle strips, packed vertices), got 2.5x less generation time & 4x less memory usage 😍

All chunks share the same index buffer + the vertices store only Z coordinate since I can compute X & Y just from a vertex index.
