DrewGraphics

Post-2018 Note: This project was 99% made during my final year of university, so it's not an accurate reflection of myself since then.

This repo contains a personal graphics engine and projects built using the engine. The purpose of this engine is to serve as a sandbox for toying with graphics techniques. It's absolutely not intended for any sort of production use.

It originally started as a purely OpenGL engine while I followed this website's guides. As I took a DirectX course at my university, I added in DirectX 11 as an optional graphics API.

Organization

There are three main projects in their respective subdirectories.

Engine is the core engine, compiled to a library.

Experiments is a set of scenes (think Unity scenes) which are essentially mini-projects. Scenes are chosen during runtime by passing in the scene name as the launch argument, or typing it into standard input.

Some scenes have a VR variant (designated by the -vr suffix). These scenes rely on an OpenVR-supported headset being connected.

CaVR is a simple proof-of-concept VR "game" I build for a senior project in university. In it, a small spaceship attached to one of the VR controllers has to navigate an infinite and ever-shrinking cave while collecting fuel cells and avoiding collision with the walls.

Getting started

The first thing you need to do is checkout the submodules:

git submodule update --init

Building

Windows

Open the DrewGraphics.sln project, then build and run.

There are four configurations:

Configuration	Description
D_GL	OpenGL Debug
R_GL	OpenGL Release
D_DX	DirectX 11 Debug
R_DX	DirectX 11 Release

macOS

Using Cmake

To build using CMake, create a new folder (e.g. build), go into that folder, run cmake on the project directory, then make the resulting makefile. Do this from the top-most directory. For example:

mkdir build
cd build
cmake ..
make
./Experiments/Experiments

Using VSCode

This is probably the easier way.

Open the workspace file, install the recommended extensions, and hit F5.

To change the scene that's launched this way, edit the args value in launch.json.
