Computer Graphics covers:
1. Basics of raster scan and random scan displays, pixels, frame buffer, and display devices.
2. Line and circle drawing algorithms (like DDA, Bresenham), polygon filling (boundary-fill, flood-fill).
3. 2D and 3D transformations (translation, rotation, scaling, shearing, reflection), homogeneous coordinates, windowing and clipping, and projection techniques.
4. Hidden surface removal methods (like Z-buffer, Painter’s algorithm), curve generation (Bezier, B-spline), shading and illumination models (Phong, Gouraud), and color models (RGB, HSV, etc.).

Visualization includes:
- Visualization of 2D/3D scalar fields, direct volume rendering, vector and flow data, high-dimensional and non-spatial data, and the basics of animation and multimedia (compression, file formats, applications in entertainment, science, etc.).

Typical important questions:
- Explain raster vs. random scan systems.
- Describe and compare line/circle drawing algorithms.
- Write short notes on display devices and frame buffer.
- Explain 2D/3D transformations with examples.
- Discuss hidden surface removal algorithms.
- What are Bezier and B-spline curves? Explain their properties.
- Describe visualization techniques for scalar and vector fields.
- Explain multimedia components and compression techniques.
