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" .

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)

• Loading GLTF/GLB (2.0) model. (Almost complete)

• 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))

• Implementing MIMALLOC for std & new/delete operator overload

• Transform hierarchy, Need a lot of optimization

• Proper lighting (Main light with shadow map, Additional light with Eventual shadow map)

• Cubemap

• GPU Instancing

• Cascade shadow map (Entire frustum)

• Frustum culling (Compute shader)

• Better soft shadow algorithm (Better PCF)
• Vulkan implementation
• Optimizing more !! (always good)
