Computer Graphics can be active or passive, explain.
Computer graphics can be categorized as either active or passive based on whether they require user input or not.
1. Active computer graphics: Active computer graphics are those that involve user interaction or real-time changes in the displayed content. These graphics require user input to modify or control the displayed images or animations. For example, video games are a prime example of active computer graphics. The user actively participates in the gaming experience by controlling characters, objects, or environments in real-time. The graphics respond to the user's actions and provide immediate feedback.
2. Passive computer graphics: Passive computer graphics are static or pre-rendered images or animations that do not require any real-time user input. These graphics are typically created and displayed without any modifications or interactions from the user. Examples of passive computer graphics include digital photographs, pre-recorded videos, or movies. These graphics are designed for passive viewing or consumption and do not change based on user input.
It's important to note that while active computer graphics require user input, both active and passive graphics can be interactive in nature. Interactive computer graphics allow users to navigate or explore the displayed content even if the graphics are passive. For example, using a touchscreen to zoom or rotate a static image would be considered an interactive application of passive computer graphics.
Computer graphics can be classified as active or passive based on their interaction and output characteristics.
1. Active Computer Graphics:
Active computer graphics involve real-time interaction with the user. These graphics systems typically include input devices such as a keyboard, mouse, or touch screen that allow the user to provide input to manipulate and control the graphics. The output in active computer graphics is immediately updated based on user actions. Examples of active computer graphics include interactive video games, virtual reality applications, and computer-aided design (CAD) software.
2. Passive Computer Graphics:
Passive computer graphics, on the other hand, do not involve real-time interaction with the user. These graphics systems typically generate static or pre-rendered images or animations that are displayed or played back without any user input. The output in passive computer graphics is predetermined and fixed before it is presented to the user. Examples of passive computer graphics include images or videos displayed on a website, pre-recorded animations shown in movies or commercials, and static visualizations generated by data analysis tools.
In summary, active computer graphics allow real-time user interaction, while passive computer graphics do not require user input and provide pre-rendered output.
