Vertex buffer即顶点缓冲区。从字面意思来看,这个词就是指储存是顶点数据的缓冲区,本质还是一个缓冲区(buffer),是占一定字节的内存。就像在C++中我们用声明并赋值一个int类型,在内存中开辟4个字节空间来储存数据,这是在CPU上进行的。而Vertex buffer是OpenGL在GPU中开辟空间储存数据。当我们运行程序绘制图形时,显卡会...
gl_invalid_operation 是OpenGL中的一个错误码,表示执行了一个非法的操作。具体到 must have element array buffer bound,这意味着当前的操作(如 glDrawElements 或glDrawElementsInstanced)需要有一个元素数组缓冲区被绑定到当前的OpenGL上下文,但实际上并没有绑定。 2. 提供可能导致此错误的常见原因 未绑定EBO:在调用...
