Rotate a heightfield from a "File Input"

hi there,

I got some single formations and mountains created and saved as .tiff heightfields. Now I want to import them into my TMD (via file input device), but also need
some control over their rotation. basically, I need something to rotate them freely clockwise/counter-clockwise in WM... Is there a way?

best regards

I haven't found a way, but I admit I've looked for only 5-10 mins. I haven't ever found a use for it. There should be a way to do it with dev build's localspace.

Hey WFab,

from what I saw, Geoglyph 2 does have a "Rotator" Macro - so it must be possible somehow.

The use  (in my case) will be to bring in some mountains into an already existing "chain of mountains" that goes rouund an area.
So I need to somehow fine-tune the rotating / align things to make them fit.

The new Dev version has better distortion that also works for rotation

WFab

Geoglyph 2 does have a rotator device, but it too works only in local space for now. The areas outside are either created as a constant or mirroring. You could easily do it outside wm, in an image editing program that supports floating point outputs.

Onkelpoe

hmmm, maybe you´re right - I could do some rotation outside of WM - but I need to do it inside of WM, to really fine-tune position and rotations.
I do not know the exact angle to rotate, when outside of WM.

I got a really large main area, surrounded by mountains (all around)
The mountians are placed ok, but in some areas, there are gaps where you would fall off the map ;)

So I need that gaps to be closed. Instead of relying on rnd mountains to hopefully show up in the areas and cascade a lot choosers or combiners, I want to precisly place some hero mountains heightfields just right into the gaps so areas are 100% blocked.

Is that why GeoGlyphs rotator moves in more of circle rather than rotate on it's self, seems the point it rotates off is NOT the center of the item your rotating

JakBB

I'm not familiar with the device, but does it have device coordinates? Try adjusting those to the center of the terrain.
Or if it doesn't have device coordinates and the device forgot them you could shift your terrain to the center, it's tedious, but may work

I went on and install Geoglyph 2, will check rotator device - I really hope it can rotate things into place...

WFab

The output will still be in localspace though, and it won't work with the release build. Too much hassle just to rotate a heightfield. WM still does not have predictive algorithms for generating terrains, it's still all data centric. So, rotating a terrain in arbitrary manner would not go well with current infinite world building apparatus. Though a rotation slider in file input itself would be easier to implement, where it rotates the heightmap BEFORE importing it into world machine. That you can add to feature request for sure.

Onkelpoe

heheh, yes that would be a neat feature! But I got no hope, we ever see this.. at least not in an acceptable timeframe

Hi, found out how to do it.

In parameters, there is a device called Transform. Use that one to rotate file input by connecting it to to small grey parameter input on the File Input device
