[Plugin] Camera OrbitOnTarget v1

MarcioAB · 15 Nov 2008, 06:32

I'm an occasional CAD user and once in SketchUP I missed the way those products behave regard Orbit, so I created this simple OrbitOnTarget tool (plugin) that more or less works similar them. Feel free to improve. This is how it works:

Activate the OrbitOnTarget tool by icon (or menu) and move the mouse over the view. The Point-inference engine will be following you to help the "Target" selection.
Double-click when you find a good "Target" point and the screen will be centered on this "Target".
Set Left-button down and drag the mouse around the screen to Rotate the View fixed on the "Target" (see more info on this below).
Set Left-button down + Shift-key down and drag the mouse in the vertical screen direction to Zoom centered in the "Target". Drag up to Zoom-in and down to Zoom-out.
Set Left-button down + Ctrl-key down and drag the mouse around the screen to Pan the View in XY plane. Even if the "Target" is not any more centered on the screen, the Zoom and Rotation will still be locked on the "Target".
If you leave OrbitOnTarget and use other functions, when you came back the "Target" will still be there (I use the global $mama_target variable for that and I hope it's name is so weird it will not conflict with any other plugin).

Regard item 3, when you drag the mouse Horizontally on the screen the View will rotate in an axis that is parallel to Global Z axis (the Blue one). When you drag the mouse Vertically on the screen the View will rotate in an horizontal axis that is Normal to your view direction (or sight direction).

Regard item 5, when you drag the mouse Horizontally on the screen the View will Pan parallel to X axis (the Red one) and when you drag Vertically parallel to Y axis (Green one). I thing this must be improved.

Obs1: When using OrbitOnTarget tool you can call the default Orbit tool (with the mouse middle-button) but then you lose the "Target". The reason is because the default Orbit tool works with a mobile target and when you leave the Orbit tool (releasing the middle-button) and get back into OrbitOnTarget, it's new "Target" is defined as the last target left by Orbit tool to avoid an abrupt View change.

Obs2: The OrbitOnTarget icon (a red bow-arrow target) is on Toolbar "MamaTools". You must activate this Toolbar using View\Toolbars\MamaTools

Obs3: First time using this forum file attach function, so just in case, this is the URL: http://pws.prserv.net/marcioab/OrbitOnTarget.zip

OrbitOnTarget

I would like to find a way to replace the default Orbit tool by this one (and it's future improved versions) and have it triggered from inside any tool via the mouse middle-button.

Regards and let's see how we can improve this.

cool script, thanks

Fortunally, you've post the zip file because the link seems not to be available. (for me at least)

Quite interesting the way, you make that tool close to my idea...
Thanks MarcioAB, let's see if other ruby 's guys will go forward...

Dear Marcio,

I already have a folder called Icons in my Plugin directory (upper case i). Could you rename your folder something like icons_OOT to distinguish your icons from those for other scripts?

Regards,
Bob

Very good!thank your work!

Sure Bob. In the mean time, if you wish to change Ruby code, could you please go to lines 144 and 145 and replace then from:

From:
cmd.small_icon = "icons/target_16.png"
cmd.large_icon = "icons/target_24.png"
To:
cmd.small_icon = "icons_OOT/target_16.png"
cmd.large_icon = "icons_OOT/target_24.png"

Thanks

Dear Marcio,

Thanks for the amendment. I have not had chance to try out the ruby as I've been out all day, but I'm sure it will come in very useful.

Kind regards,
Bob

should't the icons folder be also renamed to icons_OOT?

obrigado e um abraço.

i tried it on my macbook and it did not work. the tool bar is there and after i clicked twice on an object a dot appeared on it but other than that nothing happened.

Humm ... I do not have a Mac to check but, just to see if the sequence is the expected one:

Select the tool (on the bottom text bar there should appear short instructions). This is just to see if the tool was correctly loaded.
You will also see the Inference-point around. Just move the mouse to see if the Inference-point move around the elements.
Then double-click. The screen must re-center. (try a point that in not too close the center, but even with a minimal distance it's easy to see something happened with the screen)

Could you double-check that please ?

Also, there is a variation of this plugin for change the position of Components (in draft).

no inference point to be seen. could you post a picture of what it looks like in windows?

re-centering works but nothing else besides that. no rotate, no zoom, no pan.

Well, this is how it works here:

But I also tried to capture the video-screen with MS Windows Media 9 Encoder and the behavior became more or less like you mention. But I do not know how to fix this.

so ,any further dev.
any luck with the MMB?

xrok1 · 12 Feb 2009, 01:27

hey! the MMB double click works for me.

Humm ... my initial expectation regard the Middle Mouse Button was to replace the default tool currently associated with the MMB - that is the standard SketchUP Orbit tool - by this one. But its not possible yet.
So I think in this case it is pointless to connect any function to MMB if I can only use it when the OrbitOnTarget tool is activated.

Regard any further development: I used that code in JointSU plugin with minor changes - When you are assembling components I find useful to have "OrbitOnTarget" with the target automatically set on the origin of the component axis you are working on. So, I think the idea now is to embed this "OrbitOnTarget" code into more specific plugins.

What else could be improved in a tool like this ?

Marcio

oops i guess you made me find an SK feature thats already in place. if i MMB double click SK centers on that point (i didn't know that before now )and since SK orbit the center of the screen anyway; please explain the purpose of your plugin?

MarcioAB · 12 Feb 2009, 10:16

@xrok1 said:

Make a simple cube. Center it (using the double-click you mention) targeting any specific point over the cube and Orbit.

You will find it will not always orbit around that expected point.

The OrbitOnTarget plugin makes it orbit on the selected point (and by the way, the selection is made using the Inference Engine).

Marcio

Thanks Marcio for developing the plugin. I'm finding your approach to the controls very good. I have the feeling they will become very intuitive for me with a bit more use. I'm happy.

Regards, Ross

MarcioAB · 12 Feb 2009, 16:26

Great. Let me know if we can improve the interface or anything else.

Regards
Marcio

xrok1 · 13 Feb 2009, 01:29

O.K, thanks for the explaination, even if i never use your script thank you for making me discover the MMB function of SK without you i would have never discovered that which is a very valuable function.
