KantanMapper v2 - an approach to simple mapping

Postby snaut » Tue Feb 21, 2017 8:52 pm

Note: MottoKantan has been renamed to KantanMapper and now lives in the Palette.
Please download the latest version of TouchDesigner from here to try it out.


Hello there,

well - here we are in TouchDesigner099 land and finally a preview version of a new Kantan is ready to be shared.
You will need TouchDesigner099 build 2017.4060 which you can find here

It is highly suggested to mainly try this on windows machines as it is more tested in that environment.

I'm looking forward to all the feedback - surely there will be lots of bugs and recommendations - Thanks for testing and giving feedback!

To get started and until detailed written instructions are available, please watch the following video:
phpBB [video]


New Features are being added with this update:
- Undo / Redo via Ctrl+z Ctrl+y
- Removing keys from freeform shapes
- Converting keys on freeform shapes from curves to corners and vice versa
- Transform Copy: Hold the Alt Key while Translating, Scaling or Rotating a shape will create a copy
- various speedups and bug fixes

Here is the overview video of the additions:

this is amazing! :-)
about the "edgy" lines you mentioned,
would it be possible to assign some sort of "anti aliasing" to it?

i'm very new to TD,
so i can't give you a detailed hint how to approach this...

all the best,
Roman

Hi Roman,

it's a little tricky with Anti-Aliasing and UV Maps: If I apply anti-aliasing on the uv map there will be a seam on the edges as the UVs are direct position lookups into a texture.
If I apply Anti-Aliasing after the lookup, not only the edges of the texture will be anti-aliased but also features in the texture itself... But there must be a solution to this and I probably just don't know what to search for in terms of a solution...

Cheers
Markus

Could you not edge detect and apply AA to that Markus?

Hey Jonathan,

I guess people could post-process this after using the UV-Map output with a Remap TOP

To better manage the antialiasing of the edge, can you set the render size of UV map to 4-times the resolution, and scale it down? The Remap TOP is a low load on the GPU.

Request For Enhancement:
for large scale LEDscreen mapping, where we get an exact pixelmap in a complex pattern on a 1920x1080 image from the LED supplier which needs to be mapped, we have to enter all the exact xy coordinates for the mapping.
So now that we have the Parameter Comp, for version X in the future maybe it's an option to use standard TD custom parameters for scale, translation and rotation in MottoKantan. They have the added benefit of great value ladder options and exact number entry. This would enable very fast&exact mapping of such a pixelmap.

Hi Idzard,

Thanks for your feedback!
Do you have a template that you could share for me to see what you usually would be handed from a supplier?
Would it be useful to be able to feed a Table DAT with all the coordinates, sizes and potentially uv lookups specified?

Cheers
Markus
