Loft

Personal 3D rendering techniques playground.

Motivation

Toy renderer using Vulkan and it's full capabilities.

Modules

Base

Mostly some common classes across modules. You won't go far without this one.

FrameGraph

Frame graph implementation inspired by a nice talk by EA, about their implementation of FrameGraph in FrostBite.

Window

Very basic implementation of windowing system. Will be improved in the future.

Building

Building is done using CMake.

Windows

You need to have installed:

• CMake: Either as part of Visual Studio or https://cmake.org/download/
• Vulkan: Use LunarG SDK package here https://sdk.lunarg.com/sdk/download/latest/windows/vulkan-sdk.exe (I recommend download the latest version now, there was a mistake recently, causing this project to not work)
  • NOTE: Make sure that you have SDL2 selected in Components
  • After installation, make sure you have environment variable VULKAN_SDK set to the path with Vulkan installed.

Then you can build with cmake:

In developer console, go to project directory and use:

$ cmake -S . -B build/
$ cmake --build build/

It will build the project into build/ directory.

If you have built everything into ./build/ directory, use

$ ./build/examples/viewer/loft_viewer ~/path/to/some/file.gltf

I recommend this public repository to try out some glTF models: https://github.com/KhronosGroup/glTF-Sample-Assets

Tested assets are:

• Sponza
• SciFi Helmet
