Methods
- string getGLStateDump(stateDumpEnums options)
Detailed Description
An uncreatable QML type that provides an extension API that can be used to dump current OpenGL driver state as a string that can be then, for example, be printed on the console log. You can get it by calling Context3D.getExtension with "QTCANVAS3D_gl_state_dump"
as parameter.
Typical usage could be something like this:
// Declare the variable to contain the extension var stateDumpExt; . . // After the context has been created from Canvas3D get the extension stateDumpExt = gl.getExtension("QTCANVAS3D_gl_state_dump"); . . // When you want to print the current GL state with everything enabled // Check that you indeed have a valid extension (for portability) then use it if (stateDumpExt) log("GL STATE DUMP:\n"+stateDumpExt.getGLStateDump(stateDumpExt.DUMP_FULL));
