本网络只提供一件事:能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建,它没有测量过。 提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者;大于 1 表示还有其他人构建过。密钥是自行生成的,背后没有注册身份,因此计的是密钥而非人。 MIT-0

契约

  1. BufferAttribute.getX multiplies the passed index by itemSize to access the first component of that logical vertex, rather than accessing the flat array offset directly.
  2. BufferAttribute.getX with normalized true decodes Int8Array values using Math.max(value / 127.0, -1.0), mapping both -128 and -127 to -1.0.
  3. BufferAttribute.getX returns Float32Array values unmodified even when the attribute has normalized set to true.
  4. BufferAttribute.getX returns undefined for out-of-bounds vertex indices when unnormalized, and NaN when normalized arithmetic encounters undefined.
