Q: 2. What are the main components of computer graphics?

Ans. The main components of computer graphics include:1. Hardware: This refers to the physical devices such as the display monitor, graphics card, and input devices like keyboard and mouse, which are used to create and display visual images.2. Software: This refers to the programs and algorithms used to generate and manipulate images. It includes graphics libraries, rendering engines, and modeling tools.3. Algorithms: These are mathematical formulas and techniques used to perform tasks such as rendering, shading, and animation. Examples include the Bresenham's line algorithm and the Phong shading model.4. Data Structures: These are used to store and organize the geometric data of objects, such as vertices, edges, and polygons. Common data structures used in computer graphics include linked lists, arrays, and trees.

Q: 5. What are the challenges in computer graphics?

Ans. Some of the challenges in computer graphics include:1. Realism: Creating realistic images and animations is a major challenge in computer graphics. Achieving realistic lighting, shading, and texture requires complex algorithms and techniques.2. Performance: Computer graphics often requires high computational power and memory to render complex scenes in real-time. Optimizing rendering algorithms and utilizing hardware acceleration are important for achieving good performance.3. Data Size: 3D models and scenes can be very large and require significant storage space. Efficient data compression and streaming techniques are needed to handle large-scale graphics data.4. Interactivity: Real-time graphics applications such as video games and virtual reality require high frame rates and low latency to provide a smooth and responsive user experience. Achieving real-time interactivity can be challenging, especially for complex scenes.5. Hardware Limitations: The capabilities of graphics hardware can limit the complexity and realism of computer graphics. Keeping up with advancements in hardware technology and utilizing its capabilities effectively is important for pushing the boundaries of computer graphics.
