A custom game engine made with passion. currently working on it.
First made for visual novel in mind. now it's just a 3D engine.
Currently work in progress.
To build VIN you will need CMAKE and PYTHON.
Install both if not already installed.
Clone the repository : git clone --recursive https://github.com/HITOA/vin-engine.git
Install jinja2 package : pip install jinja2
Generate with cmake : cmake -B"./build" .
Last tested with (gcc, msvc, clang) on windows and linux : 10/24/2022
Optick is used to profile the engine : https://github.com/bombomby/optick
There is an exe version in /tool.
The sponza scene rendered in the engine : (10/22/2022)
-
Multithreading
-
Basic physics engine (accurate for VR)
-
Rewrite cleaner Cmake
-
OpenVR & OpenXR implementation
-
Texel Shading for VR (Sort of)
-
SDFDDGI (https://deepai.org/publication/signed-distance-fields-dynamic-diffuse-global-illumination)
-
PostProcessing Chain system (Simple way to do postprocessing on a rendetarget, you pass the render target to a post process chain, then it end up with all the effect. you would add post process effect like chain.Add(postprocessmat))
-
Transform hierarchy, Need a lot of optimization
-
GPU Instancing
-
Cascade shadow map (Entire frustum)
-
Frustum culling (Compute shader)
-
Hot reloading (shader)
-
UI/Font (https://github.com/freetype/freetype / https://steamcdn-a.akamaihd.net/apps/valve/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf)
-
Complete DDS texture loader
- Vulkan implementation
