We have a lot of pointclouds whith Y as the up axis. Right now it is imposible to navigate through such clouds.
Would it be possible to have a switch for the up axis?
The simplest workaround would be the rotate the Point Loader at -90 degrees about the X axis. (or 90 depending on what type of Y-up system the data is in).
We intend to provide better controls to swap coordinate system and unit scaling on the fly in the near future without the need to use the Transforms.
We also have a switch for the Up axis, but it is not exposed to the UI yet, and it requires a restart of Sequoia to engage.
To switch, locate the file “sequoia_constants.json” in the installation folder, open in a text editor and change the line
"isZUp" : 1,to
"isZUp" : 0,Then save the file and start Sequoia.
You should notice that the Axis Tripod now shows Y up, and the home grid shows Red and Blue instead of Red and Green main axes. Note that we use right-handed Y up system (equivalent to what Autodesk Maya users - when X points right, Z points towards you), as opposed to left-handed Y up coordinates. If the incoming data happens to be left-handed, an additional -1 scale of the Z axis of the Point Loader might be required to flip the axis.
That was fast. Thank you
