osgearth运行实例tests失败

lvyou

我在安装完osgearth后想要运行文件夹的tests文件夹的程序，运行完只有背景的蓝色，没有模型。有没有遇到相同情况的大佬，球球了

你可以以源码的方式自己写代码，其中添加这个代码：

setRealizeOperation(new osgEarth::GL3RealizeOperation());

如果还是不行，可能是编译的时候OpenGL的问题。需要知道你使用的 OSG 和 Osgearth 的版本信息。

如果你是基于最新vcpkg编译的话(2024-07-15)，那么 OSG 365 和 Osgearth 3.5 需要添加 OPENGL3 的变量再编译。
