OpenGL VBO错误导致系统退出

问题描述

我使用JOGL加载一个OBJ模型并使用VBO在GL画布中显示它。一切都是工作的大部分但是，有一些模型，其中顶点必须变形。例如，我有一个箭头对象，并且必须能够使箭头的茎变形，使尾部根据需要长/短，同时保持箭头的对象几何形状。
这对于渲染器的一个实例很好，但是当我尝试添加另一个到场景中时，系统退出GLDrawElements调用并输出这个错误日志。任何人都可以指向正确的方向？我完全失去了。

I'm using JOGL with to load an OBJ model and display it in a GL canvas using a VBO. Everything is work for the most part however, there are some models where the vertices must be deformed. For example, I have an arrow object and must be able to deform the stem of the arrow to make the tail as long/short as needed while maintaining the object geometry for the arrow head.This works fine for one instance of the renderer but when I try and add another one to the scene, the system exits on the GLDrawElements call and outputs this error log. Can anyone point me in the right direction? I'm at a complete loss.

推荐答案

使用查看什么调用导致错误，并检查无效您的gl调用中的数据。

Use GDebugger to see what call causes the error and check for invalid data in your gl calls.

这是非常真棒。 ：）
