Voxel Rendering Engine

This is a simple voxel rendering engine written in C++ and OpenGL, it can render voxels using conventional rasterization or raytracing.

This program is cross-platform and has been tested on Windows 7, 10, 11 and Linux and MacOS. It can load a scene from a XML file and render voxels (cubes), voxagons (rectangular prisms), water (2D triangle fan), ropes (line strips) and triangular meshes (wait, what?).
It optionally uses a greedy meshing algorithm to generate the triangular meshes for the voxels, based on the post Meshing in a Minecraft Game (Part 2) by Mikola Lysenko.
It can also render voxels like hexagonal prisms instead of cubes, and align the hexagons on all 3 orientations.
It supports Dear ImGui, the amazing GUI library used by Teardown and GTA VI.

It make use of the following libraries:

• GLAD for OpenGL function loading.
• GLFW for window management.
• GLM for vector and matrix math.
• stb for loading textures and saving screenshots.
• tinyxml2 for loading XML files.
• imgui for the Graphical User interface.

How to compile

Open a command prompt in the project folder and run the command: make

Render the example scene:
./vox_render example/

Render the castle scene:
Extract castle.7z
./vox_render main.xml

Render a converted Teardown map:
./vox_render marina_sandbox/main.xml
