[SOLVED]set standard view

Pout

I know it is possible to use Sketchup.send_action("viewIso:") to set the active_view to one of the standard views.
The problem is, when this is used in a loop like this all images return equal:

standardviews=['SV_Top','SV_Bottom','SV_Front','SV_Back','SV_Left','SV_Right','SV_Iso']
standardviews.each{|view|
if view=='SV_Top'
	Sketchup.send_action("viewTop;")
elsif view=='SV_Bottom'
	Sketchup.send_action("viewBottom;")
elsif view=='SV_Front'
	Sketchup.send_action("viewFront;")
elsif view=='SV_Back'
	Sketchup.send_action("viewBack;")
elsif view=='SV_Left'
	Sketchup.send_action("viewLeft;")
elsif view=='SV_Right'
	Sketchup.send_action("viewRight;")
elsif view=='SV_Iso'
	Sketchup.send_action("viewIso;")
end
x = Sketchup.active_model.active_view
path="c;\\"+Sketchup.active_model.title
imagename = path+view.to_s+".jpg"
Sketchup.set_status_text("Writing #{imagename}")
x.write_image(imagename,200,200,true)
}

Now when i add a messagebox at the end of the loop it seems to goes well.
This is probably gonna be something stupid, i really have an off day on coding SU ruby.

Are you doing that within a start_operation block that disables the UI?

Jim

Not 100% sure, but...

What is the Scene transition time set to? Either set it to 0, or wait for the Scene animation to finish before writing the image.

Pout

ThomThom:
no, but i'll give it a shot

Jim:
scene transitions are off

No - I was thinking that might be why it didn't work.

Maybe you can use view.refresh ?

Jim

Ah, there are no scenes, so no scene tranistions.

Oh, and even simpler:


standardviews = %w(viewTop; viewBottom; viewFront; viewBack; viewRight; viewLeft viewIso;)
standardviews.each do |view|
  Sketchup.send_action(view)
  # write image
end

Thx Jim for the code update

ThomThom,

I've tried just to see if there was any diff. and there is none.
I also already tried to do active_view.refresh after each view switch but that doesn't help either.
In the API this is the explanation on send_action:
The send_action method sends a message to the message queue to perform some action asynchronously.

I don't know if this could have something to do with it

Btw did you try the code?

Extra info, if you switch pages 'scenes) in the same loop all goes well.

thomthom

Hm...
Tried setting the camera object itself instead of issuing the SU commands?

Pout

I was thinking about that.
But I need the standard views attributes for that so i can use them in a camera definition.
I have not yet found a way to adress these standard views. (or i'm looking over it completely)

Attributes? Camera definitions?

thomthom

You mean how to set the camera vectors?

I'd think just setting the camera to match X_AXIS, YAXIS and Z_AXIS should be enough... ?

Pout

yes to 'copy' the standard cameras it would be great to be able to copy the eye, target and up of the standard cameras into new cameras so i can use those.
fact is i can't itterate over those standard cameras as shown above and i need the specific values of eye and target otherwise i need to calculate the center of the bounding box of all elements of the model to specify the eye and target.

At the other hand, maybe i'm lacking any sense today (you wouldn't be the first to say that today )

TIG

And once you set the camera eye to target vector to suit an AXIS vector you need to use Sketchup.send_action("viewZoomExtents:") to see everything ???

thomthom

The native standard view buttons doesn't zoom extent - but if that is what you want - then eye and target does not matter.

direction = Z_AXIS.reverse Sketchup.active_model.active_view.camera.set( ORIGIN, direction, direction.axes.y) Sketchup.active_model.active_view.zoom_extents

Overview of the code for each standard view (informative)

Top

direction = Z_AXIS.reverse
Sketchup.active_model.active_view.camera.set( ORIGIN, direction, direction.axes.y)
Sketchup.active_model.active_view.zoom_extents

Bottom

direction = Z_AXIS
Sketchup.active_model.active_view.camera.set( ORIGIN, direction, direction.axes.y)
Sketchup.active_model.active_view.zoom_extents

Front

direction = Y_AXIS
Sketchup.active_model.active_view.camera.set( ORIGIN, direction, direction.axes.y)
Sketchup.active_model.active_view.zoom_extents

Back

direction = Y_AXIS.reverse
Sketchup.active_model.active_view.camera.set( ORIGIN, direction, direction.axes.y)
Sketchup.active_model.active_view.zoom_extents

Left

direction=X_AXIS
Sketchup.active_model.active_view.camera.set( ORIGIN, direction, direction.axes.y)
Sketchup.active_model.active_view.zoom_extents

Right

direction=X_AXIS.reverse
Sketchup.active_model.active_view.camera.set( ORIGIN, direction, direction.axes.y)
Sketchup.active_model.active_view.zoom_extents

Iso

direction=Geom;;Vector3d.new -0.666667, 0.666667, -0.333333
Sketchup.active_model.active_view.camera.set( ORIGIN, direction, direction.axes.y)
Sketchup.active_model.active_view.zoom_extents

This emulates the standard cameras, combined with zoom extents.
