A graphics engine initially made for the final paper at Computer Graphics course at UNIOESTE. Made from scratch using C++ without using any engine to draw objects
The code dependencies are:
- OpenGL Used because of SDL2
- ImGui
- SDL2 Used for drawing pixels and only for that
- GoogleTest
The code is built using xmake and the dependencies are installed automatically through. The only exception is the ImGui library, which is included as a submodule.
xrepo.
On Linux:
xmake && xmake runOn Windows:
xmake; xmake runSometimes the dependencies are not installed correctly, due to a lot of reasons. When this happens, you can try to install manually the dependencies.
Initial scene
Hierarchy
This is where the entities are listed and created.
Inspector
When you click in a element from the hierarchy it will display into the inspector it's information
Viewport
The viewport is the main area of render, this is were the program draw frames
- Left-handed coordinate system (Adair)
- Right-handed coordinate system (Smith)
You can add the following objects to the scene:
- Sphere (IcoSphere)
- Cube
- Pyramid (tetrahedron)
- Torus
- Cone
- Cylinder
- Point light
- Directional light
⚠️ The current version of the MRX engine only supports local shading. Amongst the shading models available, you can choose between:
- Flat shading
- Gouraud shading
- Phong shading
OBS: The shading model is chosen globally.
- Apply paralelism on the rasterization
- Fix some bugs marked as TODO in the project code
- Scale window with the buttons +1 and -1.
- Base refactor
- Global shadows
- Ray casting from the camera
- Select objects with the mouse
- Ray tracing support
