Struct PbrVertex 

#[repr(C)]
pub struct PbrVertex {
    pub position: [f32; 3],
    pub normal: [f32; 3],
    pub texcoord: [f32; 2],

}

PBR 顶点（位置 + 法线 + 纹理坐标 + 切线）

用于支持法线贴图的 PBR 渲染管线。

内存布局

偏移	属性	格式
0	position	Float32x3

24	texcoord	Float32x2
32	tangent	Float32x4

示例

use anvilkit_render::renderer::buffer::PbrVertex;

let vertex = PbrVertex {
    position: [0.0, 1.0, 0.0],
    normal: [0.0, 1.0, 0.0],
    texcoord: [0.5, 0.5],
    tangent: [1.0, 0.0, 0.0, 1.0],
};
assert_eq!(std::mem::size_of::<PbrVertex>(), 48);

Fields

position: [f32; 3]

3D 位置 (x, y, z)

normal: [f32; 3]

表面法线 (x, y, z)

texcoord: [f32; 2]

纹理坐标 (u, v)

tangent: [f32; 4]

切线 (x, y, z, w) — w 是 bitangent sign
