# MoravaEngine

## About
2D/3D graphics engine written in C++ language.

It currently supports the following graphics APIs:

- OpenGL 4.5+
- Vulkan 1.2
- DirectX 11

Its current purpose is to experiment with various CG concepts and techniques:

* Phong lighting model
* Shadows (directional light, omni-directional shadows)
* Physically based rendering (PBR)
* Image based lighting (IBL)
* Screen-space ambient occlusion (SSAO)
* Particle systems
* Instanced rendering
* Surface reflection and refraction
* Framebuffers
* Post-processing
* Level of detail
* Scene editor
* Perlin noise generator
* Procedural landmass generation
* Voxel based volumes
* Marching cubes algorithm
* Physics simulations
* Skeletal animation

## Installation
Build automation based on CMake (in progress)

### Project setup:

* Install <a href="https://cmake.org/download/" target="_blank">CMake</a>

```
$ git clone --recursive https://github.com/dtrajko/MoravaEngine.git
```
```
$ cd MoravaEngine
```
* Build the MoravaEngine with CMake
```
$ mkdir ./MoravaEngine/build
$ cd ./MoravaEngine/build
$ cmake ..
```
* Open the solution ./MoravaEngine/build/MoravaEngine.sln

* Change Runtime Library from **Multi-threaded DLL** to **Multi-threaded** for the project **glfw3**  
Go to Properties > Configuration Properties > C/C++ > Code Generation > Runtime Library  
Change Runtime Library to either  
"Multi-threaded Debug (/MTd)" (Debug) or  
"Multi-threaded (/MT)" (Release)  
(All projects in MoravaEngine solution should have the Runtime Library option set to either **/MTd** (Debug) or **/MT** (Release))

* Build projects **DirectXTex** and **glfw3**

* Build the project **MoravaEngine**

<!--

* Open solution vendor/DirectXTex/DirectXTex.sln in Visual Studio.
- For projects DirectXTex, texassemble, texconv, texdiag
set Properties > Configuration Properties > C/C++ > Code Generation > Runtime Library
  Debug: Multi-threaded Debug (/MTd)
  Release: Multi-threaded (/MT)
- Build projects DirectXTex, texassemble, texconv, texdiag.

* Open solution vendor/cross-platform/glfw/GLFW.sln in Visual Studio.
- For project glfw
set Properties > Configuration Properties > C/C++ > Code Generation > Runtime Library
  Debug: Multi-threaded Debug (/MTd)
  Release: Multi-threaded (/MT)
- Build project glfw

* Build assimp with CMake
```
$ cd ./vendor/cross-platform/assimp
$ cmake .
```
* Install GLFW
```
$ cd ./vendor/cross-platform/glfw
$ cmake .
$ cmake --build .
```
* Build shaderc - use python to run
```
$ python ./vendor/cross-platform/shaderc/utils/git-sync-deps
```
* Build shaderc with CMake
```
$ cd ./vendor/cross-platform/shaderc
$ cmake .
```
* Open solution vendor/cross-platform/shaderc/shaderc.sln and build it in Visual Studio.
```
$ cd ./vendor/DirectXTex
$ cmake .
```
* Build yaml-cpp project in MoravaEngine solution in Visual Studio.
* Build all spirv-cross-* projects in MoravaEngine solution in Visual Studio.
* Build BulletCollision project in MoravaEngine solution in Visual Studio.
