Color.fromBufferAttribute()

Color.fromBufferAttribute()是Three.js中的一个方法，用于从缓冲区属性中创建颜色。

语法

Color.fromBufferAttribute(attribute: BufferAttribute, index: number, offset?: number): Color

参数

attribute — 一个BufferAttribute对象，其中包含颜色数据。
index — 颜色在属性中的开始索引。
offset — 可选参数，颜色在属性中的偏移量，默认为0。

返回值

该方法返回一个Color对象，包含从缓冲区属性中创建的颜色。

示例

const geometry = new THREE.BoxGeometry(1, 1, 1);
const colorAttribute = geometry.attributes.color;
const color = new THREE.Color();
color.fromBufferAttribute(colorAttribute, 0);

console.log(color); // 输出颜色值
