Minecraft clone written with C++ and Vulkan, node structure for infinite world chunks.

vkCraft

• Minecraft clone written with C++ and Vulkan
• Project made as a way of learning the basics about the Vulkan API.

How to run

• Download and install the required libraries
  • GLM, GLW, GLFW, STB Image and LunarG Vulkan SDK.
• On windows open the solution in Visual Studio.
• On linux run the project using CMake (added by @MolassesLover)
• Make sure that you have Vulkan compatible drivers installed.
• Build and run project.

World generator

• The world generator is based on simple perlin noise.
• Multiple generations of noise are used, one for the terrain and other one for cloud placement.
• Blocks types are decided based on the weight relative to the surface, the same goes for underwater blocks.

Chunk structure

• World chunks are organized as 3D linked list of chunks.
• Each chunk holds its data and 6 pointers to its neighbors (left, right, up, down, front, back).
• The linked structure allows for fast navigation and to find already created neighbors.

            Up
            |    Back
            |   /
            | /
  Left ---- N ---- Right
          / |
        /   |
     Front  |
           Down

To do

• Better world generation with biome support.
• Generate nodes in separate threads.
• Simplify geometry further (create only visible faces).
• Handle the water geometry separately and implement wavy shader animation.
• Try to use a geometry shader to generate the chunk geometry on the fly.
