Member Function Documentation

virtual QString PostProcessorInterface::checkOpenGL ( )
privatepure virtualslot

Check OpenGL capabilities.

This function has to be implemented and checks, if all required OpenGL extensions are available. If this is not the case, the plugin will be refused by the core to avoid crashes due to insufficient OpenGL support.

You can get the version information in the following way:

// Get version and check
QGLFormat::OpenGLVersionFlags flags = QGLFormat::openGLVersionFlags();
if ( ! flags.testFlag(QGLFormat::OpenGL_Version_2_1) )
return QString("Insufficient OpenGL Version! OpenGL 2.1 or higher required");
//Get OpenGL extensions
QString glExtensions = QString((const char*)glGetString(GL_EXTENSIONS));
// Collect missing extension
QString missing = "";
if ( !glExtensions.contains("GL_ARB_vertex_buffer_object") )
missing += "Missing Extension GL_ARB_vertex_buffer_object\n";
if ( !glExtensions.contains("GL_ARB_vertex_program") )
missing += "Missing Extension GL_ARB_vertex_program\n";
return missing;
Return an empty string if everything is fine, otherwise return, what features are missing.
virtual bool PostProcessorInterface::isStereoProcessor ( )

does post processor resolve stereo buffer

The post processor gets the left and right image as input and composes a combined stereo output.

true if implementation resolves stereo buffer, false otherwise

virtual QAction* PostProcessorInterface::optionsAction ( )

Return options menu.

If you want an options Menu or menu entry, you can return your action here. It will be shown on top of the post processors list in the options menu.

Action for a menu or menu entry
