VRaster

A simple VR app framework written in c++ (WIP).

Prerequisites

Windows 11 (This may also work on Windows 10, Ubuntu, but unconfirmed.)
C++ environment, any of the following:
- MSVC / Microsoft Visual Studio 2022
- gcc(>=10) / GNU make
CMake (>=3.16, recommended)
Vulkan SDK
- VULKAN_SDK environment variable must be set.
vcpkg

vcpkg packages

These packages are required to install.

openal-soft
freealut
glm
tinygltf
fmt
vulkan
vulkan-hpp
openxr-loader[vulkan]

CAUTION: Latest freealut header has a problem and this causes compile errors. We recommend to fix AL/alut.h installed by vcpkg manually.

before:

#include <alc.h>
#include <al.h>

after:

#include "alc.h"
#include "al.h"

Install

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=(vcpkg root path)/scripts/buildsystems/vcpkg.cmake -DCMAKE_INSTALL_PREFIX=(install path)
cmake --build . --config Release
cmake --install .
