Project Overview
“The future of graphics lies in the power of 3D rendering.”
The 3D Renderer project is an exciting exploration of the world of 3D rendering, conducted by a team of three members at Université Laval. We are utilizing OpenFrameworks with the C++ programming language to deepen our knowledge in the field of graphical rendering.
Throughout this project, we focus on harnessing the capabilities offered by OpenFrameworks, with a particular emphasis on utilizing the GPU and shaders. This allows us to create richer visuals and optimize performance in our application.
Key Features
- GPU Utilization: We are leveraging the power of the GPU to enhance rendering performance and quality.
- Shader Implementation: Our focus on shaders enables dynamic and realistic visual effects, adding depth to our rendering capabilities.
- Illumination Techniques: A significant area of learning has been the implementation of various illumination techniques, which play a crucial role in achieving realistic lighting effects in our scenes. We explored methods such as ambient, diffuse, and specular lighting to enhance the visual realism of our rendered objects.
- Rasterization Process: We adopted rasterization as our primary rendering technique, converting 3D models into a 2D image through a process that involves projecting 3D coordinates onto a 2D plane and determining pixel color based on light interactions and textures.
