在VBO中有一个正方形,但我只打算用前3个点画2个三角形,然后用相邻的3个点画出最后3个三角形,我在互联网上没有找到这类代码的许多例子,只有glMultiDrawArraysIndirect文档,但我不能在代码中运行它,至少在我更改1个轮子的drawcount时没有给它一个好的锁但是屏幕上什么也没有出现。 还有我从网站上取的drawcoun...

GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array or to the GL_DRAW_INDIRECT_BUFFER binding and the buffer object's data store is currently mapped. GL_INVALID_OPERATION is generated if glDrawArrays is executed between the execution of ...

如果缓存中保存的是顶点数据,那么usage参数中必须包含_draw;而像素缓存对象(pixel buffer object)和其它从OpenGL端获取数据的缓存则必须使用_read标识符。最后如果usage中包含_copy,那么说明应用程序会通过OpenGL端来生成数据并且保存到缓存中,然后将它作为后续的绘制操作的输入源。使用_copy标识符的一个相应例子就是...
