DH2323 Computer Graphics and Interaction - Rendering track

This is a base repository for the rendering track of DH2323 Computer Graphics and Interaction.

The repository is meant to provide a simple API to be able to write pixels to a window. Ultimately, we want to make it easy for both students and TAs in DH2323 to get started with the labs, so that more time can be put into what the students are meant to learn. The purpose of the labs is to get familiar with the fundamentals of ray-tracing and rasterization, the purpose is not to spend time on linking libraries and building boilerplate code to set up a window or a graphics context.

Dependencies

• CMake (Minimum version 3.2)

Build

git clone --recurse-submodules https://github.com/raaavioli/Rendering-fundamentals

cd Rendering-fundamentals && mkdir build && cd build && cmake ..

MacOS

CMake will generate a Makefile.

make

Which produces a binary bin/DH2323_Rendering.

Linux

If you miss any dependencies for your system see: https://www.glfw.org/docs/3.3/compile.html#compile_cmake

For Debian + Ubuntu:

sudo apt install xorg-dev
make

Which produces a binary bin/DH2323_Rendering.

Windows

When building, CMake will generate a visual studio solution DH2323_Rendering.sln in the current build directory.

• Open build/DH2323_Rendering.sln
• Find DH2323_Rendering in the Solution Explorer
• Right click -> Set as Startup Project
• Build -> Build Solution

Operating systems

The repo has currently been verified to work on:

• Windows 10 with VS2022 and VS2019
• MacOS Big Sur (M1-chip)
• Ubuntu 20.04.3 LTS

More operating systems will be added as they are verified, and the goal is to support a wide range of operating systems so that students can run from any environment.

Creating Scenes

To use the tool, one creates a class deriving from Scene (see scene.h, example_scene.h and example_scene.cpp). The created Scene subclass needs to be included into main.cpp, and added to the list of scenes at the top of the main()-function.

This way, all Scenes are selectable from the graphical settings-panel when running the program. The general approach for solving a lab assignment is to create a Scene, and implement Update, Draw and DrawGUI to output imagery in line with the assignment specification.
