如何在unity3D中将顶点数据绑定到GLSL？

// 创建一个Mesh对象
Mesh mesh = new Mesh();

// 填充顶点数据到Mesh对象
Vector3[] vertices = new Vector3[] {
    new Vector3(0, 0, 0),
    new Vector3(1, 0, 0),
    new Vector3(0, 1, 0)
};
mesh.vertices = vertices;

// 创建一个顶点缓冲区对象(VBO)
int vbo = GL.GenBuffer();
GL.BindBuffer(BufferTarget.ArrayBuffer, vbo);
GL.BufferData(BufferTarget.ArrayBuffer, mesh.vertices.Length * sizeof(Vector3), mesh.vertices, BufferUsageHint.StaticDraw);

// 创建一个顶点数组对象(VAO)
int vao = GL.GenVertexArray();
GL.BindVertexArray(vao);
GL.BindBuffer(BufferTarget.ArrayBuffer, vbo);

// 启用顶点属性
int positionLocation = 0; // 顶点位置属性的位置
GL.EnableVertexAttribArray(positionLocation);
GL.VertexAttribPointer(positionLocation, 3, VertexAttribPointerType.Float, false, sizeof(Vector3), 0);

// 在GLSL中使用顶点属性
string vertexShaderSource = @"
    #version 330 core
    layout(location = 0) in vec3 position;
    void main()
    {
        gl_Position = vec4(position, 1.0);
    }
";
int vertexShader = GL.CreateShader(ShaderType.VertexShader);
GL.ShaderSource(vertexShader, vertexShaderSource);
GL.CompileShader(vertexShader);

// 其他GLSL代码...

// 渲染顶点数据
GL.UseProgram(shaderProgram);
GL.BindVertexArray(vao);
GL.DrawArrays(PrimitiveType.Triangles, 0, mesh.vertices.Length);
