Overview

This is my second try at making a simple render engine with Vulkan in C++. The basic stuff is mostly aligned with the great tutorial from https://vulkan-tutorial.com/. Planned is instanced rasterized rendering with a simple model handler and after that raytraced and raymarched rendering with partly custom shaders. A GUI is also provided with the DearImGui Library. In addition to the renderer, a simple entity-component-system is there for convenient control of the scene and objects (the binding-in with the renderer is currently in progress).

Code Interface

The engine is designed to be (hopefully) as simple to use as possible and still provide a big range of control. The basic interface in code currently looks something like this:

Renderer renderer;
RenderConfig renderConfig;
// set render configuration like:
renderConfig.width = 800;
renderConfig.height = 600;
// ...
renderer.init(renderConfig);
// render loop
while (true)
{
    NVE_RESULT res = renderer.render();
    if (res == NVE_RENDER_EXIT_SUCCESS)
        break;
}

Models are at the moment brought in through a model handler bound to the renderer. e.g.:

ModelHandler modelHandler;
renderer.bind_model_handler(&modelHandler);

Model cube = Model::create_model(Mesh::create_cube());
cube.m_info.position = Vector3(1, 0, 3);
modelHandler.add_model(&cube);

Requirements

Folder external and in it the folders:

• GLFW
• imgui
  • {imgui_source_files}.cpp
  • {imgui_include_files}.h

For convenience, there is a script to automatically get the external dependencies and place them in the right folder. It is init-dir.sh for linux (make sure to chmod +x it before running (this is more of a note to myself to not forget it)) and init-dir.bat for windows. The script also generates the cmake stuff, so you can directly start with compiling. The script needs wget to work properly.

Some Trivia

• x is forward/back, y is right/left and z is up/down
• Classes are in PascalCase, methods_or_functions in snake_case
