conflagrantengine's Introduction

🔥 Conflagrant Engine 🔥

The Conflagrant graphics engine (OpenGL 4.0+).

Features

Entity-Component-System based implementation
Custom JSON-based scene format
GUI using Dear ImGui
Texture mapping for materials
- Diffuse maps
- Specular maps
- Normal maps
Shadow mapping for multiple directional lights
Frustum culling with bounding spheres
Voxel Cone Tracing
- Indirect diffuse/specular lighting
- Voxel-based Ambient Occlusion

Installation

Linux (Arch)

Depending on your GPU you first need to run one of these commands:

NVIDIA - pacaur -S cuda
Intel - pacaur -S intel-opencl-sdk
AMD - pacaur -S amdapp-sdk

pacaur -S ocl-icd opencl-headers glew glm jsoncpp assimp
git clone --recursive -j8 https://github.com/bwiberg/conflagrant.git
cd conflagrant
mkdir build && cd build
cmake ..
make

MacOS

Does not work at the moment, but the following should be a good start

brew install glm jsoncpp assimp
git clone --recursive -j8 https://github.com/bwiberg/conflagrant.git
cd conflagrant
mkdir build && cd build
cmake ..
make

Windows...

Does not work at the moment, but the following should be a good start

Install these libraries (preferred way is to build from source). Add their base directories to the Path env. variable.

GLEW
GLFW3
GLM
Assimp - needs to be built from source
json-cpp - needs to be built from source

Using Git for Windows (or similar), run the following:

git clone --recursive -j8 https://github.com/bwiberg/conflagrant.git

Next step is to build using CMake using one of the alternatives below:

Use CLion as IDE (my preferred solution)
Use cmake-gui.exe to create a project solution (Code::Blocks, Visual Studio, Unix Makefiles etc.)

Running examples

cd conflagrant/build/examples
./exampleN

Controls
