This week has been unusually productive. I've been working on terrain generation. Already the results are much better than previous attempts of mine. Thanks to researching the topic, I've finally come to decently understand Perlin noise. For generating and storing pieces of a massive world, I plan to adopt some of the methods used by Minecraft. Specifically, I'll be using a file format similar to the Anvil file format, which Minecraft currently uses.
I've spent some time reconsidering the previous block shape scheme I planned on implementing. For the time being, I've largely given up on finding the 'perfect scheme'. Every system I've considered has drawbacks of some kind, and all would have been a huge headache to implement. So, for now, I'm using a simplified scheme. The shape of a block is simply defined by which of the eight corners are present (256 total block shapes). In the future, I will likely consider more complex schemes, but until I find a better one, I'm just going to move forward with what I have now.
As an optimization, no hidden faces are included when the meshes are generated. This is done simply by checking if two adjacent blocks have matching corners on the touching sides.
Here are the next few things I'm going to be working on:
- Adding textures to give the world some color.
- Saving and loading sections of the world dynamically so you can move around.
- Some simple physics so that you can walk around.
