Video shooting: If you focus on shooting videos, such as daily vlogs or professional video works, Sony and Panasonic cameras are good choices. Sony has powerful video shooting functions, simple and convenient touch screen design and operation, and good focusing performance; Panasonic cameras have excellent video shooting functions, professional video parameter settings and excellent image quality performance. Daily recording of usage scenarios: If it is only used for daily recording of life, there are certain requirements for the portability of the camera.
The key to selecting a camera for novices is to meet their own needs. They must first consider the purpose, budget and parameter matching to prevent blindly pursuing high-end models to clarify the core requirements: first decide what to shoot before picking the camera. 1) If it is used for daily recording or travel, then Choose a light micro-single or card machine, such as the Sony ZV-E Canon G7X series, focusing on portability and ease of use in the automatic mode.
Clarify requirements: If taking pictures is the main focus, preference will be given to SLR or high-quality micro-singles; if taking pictures is the main focus, preference will be given to micro-singles with strong video performance. If you are pursuing portability, give priority to micro-single or small SLR (such as Canon m10); if you are pursuing cost-effective, give priority to second-hand SLR. In summary, Canon is not the only choice: different brands and models have their own advantages, and a comprehensive selection needs to be made based on budget, needs and model characteristics.


The core technology stack selects graphics rendering: 2D games: HTML5 Canvas is preferred. Its APIs are intuitive (such as ctx.drawImage (), ctx.fillRect (), which is suitable for drawing characters, backgrounds and other elements. CPU rendering performance is sufficient in simple scenes. 3D games or advanced 2D effects: Use WebGL to directly operate the GPU, support particle systems, complex visual effects, but you need to understand shaders (GLSL code) and 3D graphics concepts.

Technical feasibility JavaScript is a universal programming language that enables 3D game development through modern Web technology. Although the original Minecraft is based on Java, JavaScript can achieve similar functions in the following ways: 3D rendering engine: Build a virtual world using Three.js or Babylon.js. Game logic management: Player interaction, item generation and world rule systems need to be designed.
Cross-platform support for game development capabilities: JavaScript is the only game development language that can cover desktop, Web and mobile platforms at the same time, and is suitable for developing page games and WeChat Mini games. Technical basics: Combine HTML5 and CSS to achieve interactive logic and animation effects without relying on third-party libraries (such as Bunny Hunt). Typical game case Mario: Super Mario web version, 1:1 restore red and white machine functions and levels, implemented purely in JavaScript.
Implementation of gobang match: The core of the gobang match game lies in the functions of board drawing, chess piece placement logic, victory and defeat judgment, and online match. These functions can all be implemented through JS. For example, you can use HTML5's Canvas element to draw chessboards and chess pieces, use JS to process user click events to achieve the landing function, and write algorithms to determine victory or defeat.

1. Digital camera: Aibaifen digital camera is specially designed for campus students. It has a small and lovely appearance, and the ivory white tone conforms to the aesthetics of teenagers. 5000W pixels, beauty functions and flash support, combined with 32G storage space, can meet daily self-portraits and Vlog recording needs, making the operation simple and easy to use.

1. After Flash stopped maintenance, the efficient development of 4399 types of Mini games can be realized based on modern Web technology. The core solutions include tools such as WebAssembly, PixiJS, Three.js, Babylon.js and CreateJS. Developers can choose the appropriate technology stack based on the game type (2D/3D) and performance requirements.

2. Although the golden age of Flash games may have passed, its spiritual core has not disappeared. With the rise of independent games, many classic Flash games have been transformed into independent games and continue to inherit their characteristics. Players can support developers through convenient crowdfunding channels and enjoy the fun of these games.
