Core Concepts in Computer Graphics
Understanding the fundamentals involves exploring several key concepts that form the backbone of the discipline.
Graphics Pipeline
The graphics pipeline describes the sequence of steps involved in generating a final image from a 3D model.
Stages of the Graphics Pipeline:
1. Modeling: Creating a mathematical representation of objects.
2. Transformation: Moving, scaling, or rotating objects.
3. Lighting: Applying illumination to objects.
4. Projection: Converting 3D scenes to 2D images.
5. Rasterization: Converting shapes into pixels.
6. Fragment Processing: Calculating pixel colors.
7. Display: Presenting the final image on the screen.
Types of Graphics
- 2D Graphics: Flat images, drawings, and diagrams.
- 3D Graphics: Three-dimensional models with depth and perspective.
- Vector Graphics: Images created with paths and mathematical equations.
- Raster Graphics: Images composed of pixels.
Key Elements of Computer Graphics
- Points, Lines, and Curves: Basic geometric primitives.
- Shapes and Surfaces: Polygons, meshes, and complex surfaces.
- Textures and Colors: Surface details to enhance realism.
- Lighting and Shading: Techniques to simulate light effects.
