我一直不成功不知为什么？
请大家帮帮忙
skyTex = new QOpenGLTexture( QOpenGLTexture::TargetCubeMap );skyTex->create();skyTex->bind( 0 );skyTex->setSize(512,512);skyTex->allocateStorage();//skyTex->setMipLevels(0);//skyTex->setLayers(1);
QString fileName;fileName = "/Users/army/code/QT_OpenGL/OpenGLQT_Demos/assets/skybox/snow_posx.jpg";QImage image_posx( fileName );
skyTex->setData( 0,0,QOpenGLTexture::CubeMapPositiveX,QOpenGLTexture::RGBA,QOpenGLTexture::UInt8,image_posx.bits() );
&nb ..

视口要位于盒子里面，（顺便描述下你遇到的问题）

你试过QOpenGLTexture这个类吗？
问题应用上面的skybox是全黑的

这样也尝试了
skyTex = new QOpenGLTexture( QOpenGLTexture::TargetCubeMap );
skyTex->create();
skyTex->bind();
skyTex->setSize(512,512);
skyTex->allocateStorage();
QString fileName;
fileName = "/Users/army/code/QT_OpenGL/OpenGLQT_Demos/assets/skybox/snow_posx.jpg";
QImage image_posx( fileName );
skyTex->setData( 1,1,QOpenGLTexture::CubeMapPositiveX,QOpenGLTexture::RGBA,QOpenGLTexture::UInt8,image_posx.bits() );
fileName = "/Users/army/code/QT_OpenGL/OpenGLQT_Demos/assets/skybox/snow_posx.jpg";
QImage image_negx( fileName );
skyTex->setData( 1,1,QOpenGLTexture::CubeMapNegativeX,QOpenGLTexture::RGBA,QOpenGLTexture::UInt8,image_negx.bits() );
fileName = "/Users/army/code/QT_OpenGL/OpenGLQT_Demos/assets/skybox/snow_posx.jpg";
QImage image_posy( fileName );
skyTex->setData( 1,1,QOpenGLTexture::CubeMapPositiveY,QOpenGLTexture::RGBA,QOpenGLTexture::UInt8,image_posy.bits() );
fileName = "/Users/army/code/QT_OpenGL/OpenGLQT_Demos/assets/skybox/snow_posx.jpg";
QImage image_negy( fileName );
skyTex->setData( 1,1,QOpenGLTexture::CubeMapNegativeY,QOpenGLTexture::RGBA,QOpenGLTexture::UInt8,image_negy.bits() );
fileName = "/Users/army/code/QT_OpenGL/OpenGLQT_Demos/assets/skybox/snow_posx.jpg";
QImage image_posz( fileName );
skyTex->setData( 1,1,QOpenGLTexture::CubeMapPositiveZ,QOpenGLTexture::RGBA,QOpenGLTexture::UInt8,image_posz.bits() );
fileName = "/Users/army/code/QT_OpenGL/OpenGLQT_Demos/assets/skybox/s ..

使用纯opengl是没有问题，如下面代码可以正常显示
glActiveTexture( GL_TEXTURE0 );
GLuint texID;
glGenTextures(1,&texID);
glBindTexture( GL_TEXTURE_CUBE_MAP,texID );
const char * suffixes[] = { "posx", "negx", "posy","negy", "posz", "negz" };
GLuint targets[] = { GL_TEXTURE_CUBE_MAP_POSITIVE_X,
GL_TEXTURE_CUBE_MAP_NEGATIVE_X,
GL_TEXTURE_CUBE_MAP_POSITIVE_Y,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y,
GL_TEXTURE_CUBE_MAP_POSITIVE_Z,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Z};
for( int i = 0; i < 6; i++ ) {
QString fileName = QString( "/Users/army/code/QT_OpenGL/OpenGLQT_Demos/assets/skybox/" ) + "snow_" + suffixes + ".jpg";
QImage image( fileName );
glTexImage2D(targets, 0, GL_RGBA,image.width(), image.height(),0, GL_RGBA, GL_UNSIGNED_BYTE, image.bits());
}
// 典型的立方体映射设置
glTexParameterf(GL_TEXTURE_CUBE_MAP, GL_TEXTURE_ ..

你好！请问问题是怎样解决的呢？
