Please read carefully

General Notes

Requirements:

• CMake >= 3.14.0
• Vulkan SDK >= 1.2.162.0

Dependencies:

• submodules in "root/external/"
  • spdlog
  • nlohmann-json
  • tinygltf
  • tinyies
  • tinyldt
  • tinyexr
  • tinyply
  • tinyobjloader
  • imgui
  • ImGuizmo
  • imoguizmo
  • stb
  • glm
  • glslang

Notes:

Clone git with submodules

git clone --recursive

If build script is not used, use CMake from root/ like

# Adjust `-G <generator-name>` accordingly or remove it
cmake -H. -B_project -G "Visual Studio 16 2019" -A "x64"

Compiling On Win

Use the provided make.bat file to generate a Visual Studio project in root/_project/. Use make.bat clean to remove all project files. If changes to cmake are not visible, delete root/_project/CMakeCache.txt and run make.bat again.

make # generate project files in 'root/_project/'
make install # install release build in 'root/_install/'
make install <install_dir> # install release build in <install_dir>
make clean # delete 'root/_project/' and 'root/_install/'

Compiling On Linux

Use the provided makefile file to generate a project in root/_project/ or open the CMakeLists.txt file in an IDE like Qt Creator or CLion. Use make clean to remove all project files. If changes to cmake are not visible, delete root/_project/CMakeCache.txt and run make.bat again.

Maybe you have to configure some variables for the Vulkan SDK beforehand.

export VULKAN_SDK=/your_path_to_vulkan_sdk/VulkanSDK/1.0.37.0/x86_64
export PATH=$PATH:$VULKAN_SDK/bin
export LD_LIBRARY_PATH=$VULKAN_SDK/
export VK_LAYER_PATH=$VULKAN_SDK/etc/explicit_layer.d
