algorithmic modeling for Rhino

Hi guys, hi David,

Just a simple question: in the drawing method of the TextTag 2D there is a Boolean parameter for justification of the text: Center-Center or Lower-Left.

Is it possible to add another 2 options: Middle-Left and Middle-Right?

Thanks,

Dmitriy

It is possible. I'll see what it takes, if it's a lot of work I may put the wish on the GH2.0 pile.

Thanks David.

Hopefully it is not much work - and we can see it still the GH1.0.

Hi David,

Any chance to introduce justification in the next release(s)?

Would really need it.

Thanks,

Dmitriy

It'll be available in 0.9.0062

Fantastic!

Guess relevant method will be added in RhinoCommon as I need to use it via RhinoCommon.

Thanks a lot David!

No, there didn't seem to be a way to do it in RhinoCommon. You can create a TextEntity with justification but I couldn't figure out how to render it in the viewports. So I'm still using Rhino.Display.Text3D and figuring out how to adjust the TextPlane based on the justification and boundingbox properties.

Ok, I am a bit confused. What about 2D Tag?

Will it be possible to draw 2D tag with 9 points justification via Args.Display.Draw2dText?

Thanks,

Dmitriy

It seems that Draw2dText only has a single boolean argument for middle justified text. If you want more control you may have to draw camera aligned 3D text.

It's a bit more involved but totally possible in your own code.

Thanks David,

The issue with the Tag2D is that size is in pixels and always the same.

I guess Text3D will change the size if Zooming In or Out.

Regards,

Dmitriy

You have to adjust the font-size based on how far away you draw the text. Basically you draw the 3D text on the camera near plane, figure out how many pixels/unit there are on that distance and then adjust your font-size accordingly.

Hi David,

Can you provide some initial example for camera aligned 3D text?

Thanks,

Dmitriy

This file draws the text in place (not on the camera near plane) so it will get occluded by geometry in front of it. It does however adjust the text size so they all appear equally big.
