如何在openGL ES 3 android中创建VAO

n-要返回的VAO数量（数量）；

数组-具有已创建对象标识符的n个元素的数组；

偏移量= 0。

创建VAO时，使用以下功能将其设为最新：GLES30.glBindVertexArray（VAO [0]）。绑定VAO后，所有调用（例如glBindBuffer，glEnableVertexAttribArray，glVertexAttribPointer）都会影响当前的VAO。

public class Renderer implements GLSurfaceView.Renderer {
    private int[] VBOIds = new int[2]; // VertexBufferObject Ids
    private int[] VAOId = new int[1]; // VertexArrayObject Id

    public Renderer(...) {
        // create vertex buffer objects
        VBOIds[0] = 0;
        VBOIds[1] = 0;
        GLES30.glGenBuffers(2, VBO, 0);
        ...
        GLES30.glBindBuffer(GLES30.GL_ARRAY_BUFFER, VBO[0]);
        GLES30.glBufferData(GLES30.GL_ARRAY_BUFFER, verticesData.length * 4,
                    vertices, GLES30.GL_STATIC_DRAW);
        ...
        GLES30.glBindBuffer(GLES30.GL_ELEMENT_ARRAY_BUFFER, VBO[1]);
        GLES30.glBufferData(GLES30.GL_ELEMENT_ARRAY_BUFFER, indicesData.length * 2, indices, GLES30.GL_STATIC_DRAW);
        ...
    }

    public void onSurfaceCreated(GL10 glUnused, EGLConfig config) {
        GLES30.glGenVertexArrays(1, VAOId, 0); // Generate VAO Id
        GLES30.glBindVertexArray(VAOId[0]); // Bind the VAO
        // invokes commands glBindBuffer, glEnableVertexAttribArray, 
        // glVertexAttribPointer for VBOs
        ...
        // Reset to the default VAO (default VAO always is 0)
        GLES30.glBindVertexArray(0);
    }

    public void onDrawFrame() {
        ...
        GLES30.glBindVertexArray(VAOId[0]); // active VAO
        // Draw on base the VAO settings
        GLES30.glDrawElements(GLES30.GL_TRIANGLES, indicesData.length,
                      GLES30.GL_UNSIGNED_SHORT, 0);
        // Return to the default VAO
        GLES30.glBindVertexArray(0);
    }
}```
