three.js-场景物体增加标记/annotation

在3d场景中是无法绑定点击事件,那么用户就无法与场景进行交互,而three.js就为我们提供了raycaster功能。可以用raycatser与场景进行交互

示例:

three.js-场景物体增加标记/annotation》有2个想法

  1. Hi, huolalaweb.com

    I’ve been visiting your website a few times and decided to give you some positive feedback because I find it very useful. Well done.

    I was wondering if you as someone with experience of creating a useful website could help me out with my new site by giving some feedback about what I could improve?

    You can find my site by searching for “casino gorilla” in Google (it’s the gorilla themed online casino comparison).

    I would appreciate if you could check it out quickly and tell me what you think.

    casinogorilla.com

    Thank you for help and I wish you a great week!

    1. Hello, I’m very sorry to see your message and reply to your letter just now.
      Thank you for your affirmation and encouragement. This is just my personal technology sharing blog. It is not profitable. It may not help your casinogorilla.com. But you can try from the following aspects: first, you can increase the exposure of the website so that it can be collected by web crawlers; then, you can add content to attract users to use.
      Wish you success!
