DreamRealm

DreamRealm is a 3D Rendering Engine built with C++ and the Opengl graphics API with upcoming support for Vulkan

Details:

Features implemented so far are:

• Cmake support
• Environment Light (Point light, Directional light)
• Scene Camera
• Cloud simulation using perlin noise texture lookup on pixel shaders
• Distant Fog effect using linearized depth buffer technique
• CrunchMath support for graphics related calculations
• Mesh loading with support for animations with the Open Asset Import Library (assimp)
• Image/Texture loading with STB image library
• GLFW support for windows creation, reading input, handling events

Features to be implemented:

• Anti-aliasing (MSAA Technique)
• Instancing
• Deferred Shading Technique
• Shadow Mapping
• Bloom Effects
• High Dynamic Range Rendering (HDRR)
• Physical Based Rendering (PBR)
• Rainbow light
• Text Rendering
• Level Editor
• Vulkan Support
• Voxel Rendering
• Ray Tracing

More Detailed Roadmap of DreamRealm:

• Project Todo's, Inprogress & Backlogs

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

The basic requirements for building the executable are:

• CMake 3.8+
• C++ compiler

Cloning the project

git clone --recursive https://github.com/harlexkhal/DreamRealm <Your-Build-Directory>

Building project with Cmake and building binaries

This program has been tested on Windows 10 and binaries built with visual studio 2019. but should work under any system that fulfils the aforementioned requirements.

Building Project Solution Files

Make sure to set the environmental path variable of cmake. then on the parent directory of the project using cli. run

cmake .

On Visual studio. Build project, on the first build you would get an error of missing assimp static library. rebuild project and it would be fixed. After a successful build from parent source directory go to DreamRealm\Dependencies\Assimp\bin\Debug and copy assimp-vc142-mtd.dll paste it into DreamRealm\Debug from parent directory. Now navigate to Dependencies\GLFW\src\Debug also from parent directory and copy glfw3d.dll then paste it into DreamRealm\Debug from parent directory. now in your current directory which is DreamRealm\Debug you would see the binary DreamRealm.exe. Now navigate to DreamRealm by going one directory backwards and copy the src folder and paste into DreamRealm\Debug. and now you are done you can run DreamRealm.exe from there or alternatively run it from the compiler.

Some screenshots along the way of developing:

Built With

• OpenGL - API used for communicating with graphics drivers
• GLFW3 - Used for display, reading inputs, and handling events
• CrunchMath - Used for graphics related calculations
• Open Asset Import Library (assimp) - Used for loading meshes
• STB image - Used for loading images/textures
