我尝试使用glDrawElements方法在屏幕上绘制一个四边形，如下所示：

glDrawElements(GL_TRIANGLES, model.get_vertex_count(), GL_UNSIGNED_INT, 0)

为了获得索引，我编写了以下方法：

@classmethod
    def bind_indices_buffer(cls, indices: list[int]):
        indices = numpy.array(indices, dtype=numpy.uint32)  # convert the data into an unsigned integer array
        vbo_id = glGenBuffers(1)
        cls.__vbos.append(vbo_id)
        glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, vbo_id)
        glBufferData(GL_ELEMENT_ARRAY_BUFFER, indices, GL_STATIC_DRAW)

对于顶点：

@classmethod
    def store_data_in_attribute_list(cls, attribute_number: int, data: list[float]):
        data = numpy.array(data, dtype='float32')   # convert the data into a float32 array
        vbo_id = glGenBuffers(1)                    # create 1 VBO buffer
        cls.__vbos.append(vbo_id)                   # appends it to the VBO list in the class
        glBindBuffer(GL_ARRAY_BUFFER, vbo_id)       # binds the buffer to use it
        glBufferData(GL_ARRAY_BUFFER, data, GL_STATIC_DRAW)  # specifies the buffer, data and usage
        glVertexAttribPointer(attribute_number, 3, GL_FLOAT, False, 0, None)  # put the VBO into a VAO
        glBindBuffer(GL_ARRAY_BUFFER, 0)

如果你想看到其余的代码，我已经粘贴到我的最后一个问题，这些片段是唯一的变化
