Rview 2

vulkan 1.4 simple cross platform multiplayer gltf file viewer. can load any gltf model, pbr materials, textures, alpha blending, fk and ik animations, actions and non-linear animations full support for glsl shaders ( compile with glslc/glslangvalidator for vulkan ). gltf extensions are wip.

downloads

needed for default models: ⏬resources

latest binaries

wip

controls:

left click - move default model to location
ESC - exit
wasdeq - camera controls, for debugging

Debug Menu - allows u to choose model to move/scale/rotate/change animation etc.
Drag & Drop - any model can be loaded if u drag and drop it in the window

notes:

All builds are x64. windows builds are compiled with mingw. The binary is only linked to the libraries statically.

build requirements

• c++20 compiler
• vulkan 1.4
• sdl3
• glm
• 🌟 fastgltf -> simdJSON
• stb
• GameNetworkingSockets -> OpenSSL and Protobuf -> abseil

compiling

requirements

• ninja (not required but highly preferred)
• cmake
• vulkan sdk ( with glslc or 🌟slangc ) | slang comes with the vulkan sdk since version 1.3.296.0.
• gcc | mingw (for windows or cross compiling)
• openssl | openssl compiled with mingw -> msys/strawberry perl (windows)
• install/make sure vulkan sdk is installed and make sure VULKAN_SDK is set and glslc is under VULKAN_SDK/Bin/
• install openssl on linux or build OpenSSL and ensure it's compiled and configured with mingw64 with no-shared and make sure OPENSSL_ROOT_DIR is set, msys2 can be used to make it easier, instructions follow if needed.
• make sure resources are in resources directory
• clone recursivelygit clone --recursive or run either git pull --recurse-submodules or git submodule update --init --recursive after cloning to install the dependancy submodules

linux

• download resources and extract to resources directory in project root
• install vulkan sdk
• install openssl
• configure cmake from project source e.g:
  • cmake -G Ninja -S . -B build -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++
• build the project:
  • cmake --build build

windows

• download resources and extract to resources directory in project root
• install vulkan sdk
• use msys2 to build openssl from source
  • cd /path/to/openssl
  • export PATH="/path/to/mingw/bin:$PATH"
  • export OPENSSL_USE_STATIC_LIBS=ON
  • ./Configure --prefix=$PWD/dist no-idea no-mdc2 no-rc5 no-shared mingw64
  • make depend && make && make install
• set OPENSSL_ROOT_DIR environment variable to /path/to/openssl/dist or wherever u set the install prefix for openssl to
• configure cmake from project source e.g:
  • cmake -G Ninja -S . -B build -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++
• compilers have to match, if u build with mingw, then openssl has to be built with mingw too and the other external projects in cmake
• build the project:
  • cmake --build build

feel free to contact me if u need help
