Exploring Computer Graphics Concepts

What is the primary purpose of computer graphics?

• To create visual representations of data and information.

• To store large amounts of data efficiently.

• To improve computer processing speed.

• To enhance audio quality in multimedia.

Define raster graphics and vector graphics.

• Raster graphics are always higher quality than vector graphics.

• Raster graphics are based on mathematical formulas, while vector graphics are pixel-based images.

• Vector graphics can only be used for photographs.

• Raster graphics are pixel-based images, while vector graphics are based on mathematical formulas.

What is the role of a graphics processing unit (GPU)?

• To control the main processing unit's clock speed.

• To enhance audio processing capabilities.

• The role of a GPU is to accelerate graphics rendering and perform parallel processing tasks.

• To store and manage system memory efficiently.

Explain the concept of rendering in computer graphics.

• Rendering is the process of creating 3D models from 2D images.

• Rendering is the process of generating a 2D image from a 3D model using computer programs.

• Rendering refers to the compression of graphics files for storage.

• Rendering is the technique used to animate characters in video games.

What are the differences between 2D and 3D graphics?

• 2D graphics are three-dimensional and use depth, while 3D graphics are flat.

• 2D graphics are flat and use width and height, while 3D graphics add depth, incorporating width, height, and depth.

• 2D graphics can represent depth through shading, while 3D graphics cannot.

• 3D graphics only use height and depth, while 2D graphics use width and height.

What is a pixel, and how does it relate to image resolution?

• A pixel is a type of camera lens used in photography.

• A pixel is the smallest unit of a digital image, and image resolution indicates the total number of pixels in an image, affecting its clarity and detail.

• A pixel is a measurement of physical size in inches.

• Image resolution is determined by the color depth of an image.

Describe the process of texture mapping.

• Texture mapping is the process of creating 3D models from scratch.

• Texture mapping is the process of applying a 2D image (texture) to a 3D model's surface to enhance its visual detail.

• Texture mapping involves changing the color of a 3D model's surface without using images.

• Texture mapping is the technique of lighting a 3D model to make it appear more realistic.

What is anti-aliasing, and why is it important in graphics?

• Anti-aliasing is used to create 3D effects in graphics.

• Anti-aliasing increases the brightness of images.

• Anti-aliasing is important in graphics because it enhances image quality by reducing jagged edges, resulting in smoother and more visually appealing images.

• Anti-aliasing is a technique for adding more colors to an image.

Explain the significance of color models in computer graphics.

• Color models are irrelevant in modern computer graphics.

• Color models are significant in computer graphics for standardizing color representation, ensuring consistency across devices, and enabling accurate color manipulation.

• Color models have no impact on digital images.

• Color models are only used for printing purposes.

What are some common applications of computer graphics in various industries?

• Common applications of computer graphics include entertainment (visual effects, animations), healthcare (medical imaging), architecture (building visualization), gaming (immersive graphics), education (interactive tools), and advertising (marketing visuals).

• Social media management

• Financial analysis

• Weather forecasting
