Provides means to print current GL driver state info. More...
|Import Statement:||import QtCanvas3D 1.1|
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));

string getGLStateDump(stateDumpEnums options)
Returns OpenGL driver state with given options as a human readable string that can be printed. Optional paremeter options may contain bitfields masked together from following options:
GLStateDumpExt.DUMP_BASIC_ONLYIncludes only very basic OpenGL state information.
GLStateDumpExt.DUMP_VERTEX_ATTRIB_ARRAYS_BITIncludes all vertex attribute array information.
GLStateDumpExt.DUMP_VERTEX_ATTRIB_ARRAYS_BUFFERS_BITIncludes size and type from all currently active vertex attribute arrays (including the currently bound element array) to verify that there are actual values in the array.
This command is handled synchronously.
