将float3从Swift结构传递到金属着色器

struct MyStruct {
    var position: float3
}

vertex float4 myVertexShader(MyStruct vertexIn [[stage_in]], constant MyStruct& uniforms [[buffer(0)]]) {
    // 使用vertexIn.position和uniforms.position进行处理
    // ...
}

struct Uniforms {
    var position: float3
}

let uniforms = Uniforms(position: float3(1.0, 2.0, 3.0))
renderEncoder.setVertexBytes(&uniforms, length: MemoryLayout<Uniforms>.stride, index: 0)

vertex float4 myVertexShader(MyStruct vertexIn [[stage_in]], constant Uniforms& uniforms [[buffer(0)]]) {
    // 使用vertexIn.position和uniforms.position进行处理
    // ...
}
