Sandbox for Vulkan, SPIR-V and glTF

This R&D project is a sandbox to evaluate Khronos API's like Vulkan, SPIR-V and glTF.

Work in Progress

Vulkan

• Done

SPIR-V

• Done

glTF

• Done

General

• Prefilter IBL on the fly
• Remove Slim KTX2 dependency
• Remove BasisU dependency
• Remove TinyGLTF dependency

How to build?

• Vulkan SDK 1.3.231.1 or later
  • Earlier versions do work with high chance but are not tested
• Eclipse C/C++ Development Tooling
  • GCC for Linux
  • MinGW64 for Windows

Build steps for Eclipse

1. Import the projects into Eclipse.
2. Select Windows or Linux build - either as Release or Debug build.
3. Build the TinyEngine project first.
4. Build the ExampleXX project.
5. Working directory is ExampleXX both for Release and Debug build.

Tested platforms

• Windows 10 (64bit)
• Ubuntu 20.04 LTS (64bit)

Used tools

• Eclipse C/C++ Development Tooling
• MSYS2 on Windows
  pacman -S mingw-w64-x86_64-gcc
pacman -S mingw-w64-x86_64-gdb

Used assets

• glTF 2.0 Sample Models
• glTF Sample Environments

Used libraries and code

• GLFW
  pacman -S mingw-w64-x86_64-glfw
• glm
  pacman -S mingw-w64-x86_64-glm
• OpenImageIO
  pacman -S mingw-w64-x86_64-openimageio
• Shaderc
  pacman -S mingw-w64-x86_64-shaderc
• Slim KTX2
  • basis_universal
• tiny glTF
• volk
  • Integrated in TinyEngine
• Vulkan SDK

Limitiations by purpose

• Vulkan
  • During minimize, the update loop is stopped.
  • Helper methods for initalization are not optimal and causing a stall on the GPU. This is done for Vulkan code simplicity.
• Tooling
  • gcc (Windows and Linux)
  • C++17
  • 64bit only
