Dear ALL, How am supposed to use the GLGUILayout ,I follow the examples in the LCL/Demo/Interface/GuiDemo, but there is very limited description about hwo to use it, So I couldn't even formed the GLButton to lay on screen at the design time. Is there any step by step definitions? Defnition as per the source code, but that didn't help a lot. A sample for the Gui interface system. To use the Gui you must place a TGLGUILayout component on your form, this is a storage for Gui layouts within a single...

Dear ALL, Is there any advances in the rectangle selection mechanism of GLScene.? Existing system was very slow and not fuctional so I'll appreciate those who guide me on how to do that in efficient way. I also appreciate for those who are familiar with CodeTyphoon framework, if there is any intrinsic functionality for selection. Regards,

Determining which is nearest of farthest is not a issue for me for the time being or at least it is not main goal for me. For now I mainly concentrate whether the objects are selected or not. IThe exact problem in my case is: With the current mechanism if there is a object with nested childs, then the main/root object is added and the childrens is added to the selection list but I would like to add onlythe main/root object to the selection list. It means that, I have to develop amechanism which determines...

Thanks in advance Jerome, It seems that mine is hardest case. I have to perform selection on region and not selecting objects one by one, so there will be set of objects, where I have to sort out the hierarchy. How am I supposed to implement that? In any case it boils down to this how you can iterate through all childs or vice versa through parents so that I can avoid that I'm not adding already parent of another child.

Dear All, In my secene I have objects which have numerous childrens in their child stack, some of them might have 3, some 4 or even more. It is possible to have 3 or more level of nested children in the hierarchy, and f I use the GLGizmoEx selection feature depending on the selection rectangle If user selects only the lowest children in hierarchy, normally as expected the modifiers ( move, rotate, scale ) will affect only by that selected child. Instead of that; I want the parent of these child objects...

Dear Jerome, PLease find the test case project at the attachment it is minimalistic, use right mouse button to rotate on the left screen you will experience the lagging. On right side there is a ortho camera, if delete that orthographic camera then everything is fine and function properly.
