记录一些OpenGL编写中的问题 NetEase
BOOST_EXCEPTION_DISABLE
记一个boost问题：
x.obj : error LNK2019: unresolved external symbol "void __cdecl boost::throw_exception(class std::exception const &)" (?throw_exception@boost@@YAXABVexception@std@@@Z) referenced in function "void __cdecl boost::asio::detail::do_throw_error(class boost::system::error_code const &,char const *)" (?do_throw_error@detail@asio@boost@@YAXABVerror_code@system@3@PBD@Z)
初步查询资料得知是因定义了BOOST_EXCEPTION_DISABLE引起
在此宏被定义后需要用户自定义如下函数 void throw_exception( std::exception const & e ){}
或者在编译选项中使用/GX 或是 /EHsc，这样告诉编译器ENABLE EXCEPTION HANDLE，也可以。
纹理贴图不是2^n的大小时渲染错误
OpenGL 3.3遇到纹理贴图像素不是$2^n$时候，加入
glPixelStorei(GL_UNPACK_ALIGNMENT, 1);
具体参数待看

cpp thread crash
记一个问题
所有关联有效线程的std::thread在析构前都要被join或者被detach.
std::thread thread_lloyd(&pccvt::PCCVTOptimizer::lloyd, &m_pccvt, value); thread_lloyd.detach();
OpenGL draw lines
// Note: glLineWidth is deprecated in OpenGL core profile, // for now we still use it if we got a compatibility profile, // but for core profile, we are for now unable to display // thick lines (TODO: develop a shader for that, painful...)
好吧我笑死了

311-Instancing(sphere),在使用实例的时候，第二个model占用4个location，所以第三个insColor要指定location=5
layout (location = 0) in vec3 position; layout (location = 1) in mat4 model; layout (location = 5) in vec4 insColor;
- Indicies 指的是单个实例的模型从哪个offset开始画，而不是这个实例的第offset个开始画
void glDrawElementsInstanced(GLenum mode, GLsizei count, GLenum type, const void *indicies, GLsizei primcount);
