[Plugin] Transformation Inspector

It would be more 'intuitive' if there was some guidance about which bits of the transformation matrix did what, and how they interact [especially rotation/scaling/handing] etc

trans=trans.to_a

        scalex=Math.sqrt(trans[0]**2+trans[1]**2+trans[2]**2)
        scaley=Math.sqrt(trans[4]**2+trans[5]**2+trans[6]**2)
        scalez=Math.sqrt(trans[8]**2+trans[9]**2+trans[10]**2)
                 
        scale=scalex
        scale=scaley if scaley>scale
        scale=scalez if scalez>scale

        puts "         <pos>#{trans[12]} #{trans[13]} #{trans[14]}</pos>\n"
        puts "         <scale>#{scale}</scale>\n"   
        puts "         <rotation>\n"
        puts "            <matrix>\n"
        puts "               #{trans[0]/scalex} #{trans[4]/scaley} #{trans[8]/scalez} #{trans[1]/scalex} #{trans[5]/scaley} #{trans[9]/scalez} #{trans[2]/scalex} #{trans[6]/scaley} #{trans[10]/scalez}\n"
        puts "            </matrix>\n"
        puts "         </rotation>\n"

Yea - that is my plan as well. And I want to be able to create matrices from the Geom::Transformation helper methods so one can visualize what they do.

I started adding tooltips for scaling and translation - but the rotation turned out to be more complex so I put it on hold until I better understood what it did - as RS for the whole 3x3 matrix felt a bit too generic.

This is great!

Actually I have though for some time to do a port of one of my MentalRay plugins that does pretty much the same.
Now I don't have to.

What I would like is a more user friendly GUI.
Something like this:

Translate  X  Y  Z
Rotate     X  Y  Z
Scale      X  Y  Z
Shear      X  Y  Z

Rotate Order  (dropdown with; 1; XYZ, 2; YZX, 3; ZXY, 4; XZY, 5; YXZ, 6; ZYX
Rotate Axis   X  Y  Z

World Rotate Pivot   X  Y  Z
World Scale Pivot    X  Y  Z

Edit: I just realised that you can easily go back to a undeformed state simply by doing a negative transform of the applied one.
Thats even better...

Thanks TT - I'd grown so used to the Maya channel box that I was making dyna-components that do this - cept I had to make one for every object! This is so useful.
I'd love to see units incorporated and that slick java UI you do. Some sort of mini-icon for the rows might be helpful, too.

this is the maya channel box

I'd like a contextual to "reset" a component position.

I'd like to be sure my component origin is truly at a 0.0.0 position.

Transformation inspector is able to help me to do this ( and it's very efficient and I thank you )

By the way I can mount complex scene using External sketchup files as reference, and thanks to you they are perfectly well located in the main scene.

Could you help me get a right click substitute for transformation inspector.

I'd like to select a component and right click to :
TransfoMenu -> reset position
TransfoMenu -> reset scale
TransfoMenu -> reset rotation
TransfoMenu -> reset all

thanks

And I promise there will be a new toy for you soon*!

Speaking of "new toy", what ever happened to the gizmo for Vertex Tools?

Summer happened. And life in general. Sorry it's taking so long.

Reset position would place it at 0,0,0?
Reset rotation would align it to the axis of the parent context?

transf inspector output i am trying to understand how the transformation matrix works, and i notice a difference between what is shown in the matrix using your plugin, and what is supposed to be shown refering to http://www.martinrinehart.com/models/tutorial/tutorial_t.html

i took a component, rotated it 45 degrees, and this is what "transformation inspector" shows

However, according to martinrinehart, i would expect the negative value to be first line second row

I am surely missing something; but can you explain the differrence?

i found the reason

seems that martinrinehart put the minus sign in the wrong place
