Geometry Viewer question

Beginners

Hello

I’m trying to setup a piece of geometry I imported to display properly, and am having some camera clipping issues…Where does one control the camera clipping?

Thanks

Bring up the Display Option in the Geo Viewer using the ‘p’ key or by selecting from the right-click menu. Then go to the Culling page in that dialog, you’ll find the Near/Far clipping planes there.

if you can’t view your geometry properly with the default settings of the viewer, would you mind sending your model to support@derivative.ca so I can take a look? please let me know which version of TouchDesigner you are using as well. thanx!

I’m having a hard time finding any documentation on the geometry viewer…Essentially I have a building I’m building some LED previz for.
The geo loads fine, but I would like to be able to place my camera properly and see it framed in a way that makes sense.
The wiki page on the geo viewer does not give any solid guidance.
Are there any ressources to find out more about this tool? Seems like the only place where you can really see what you are doing with 3d objects?

Thanks
Alex

Another question…When I’m trying to move my camera around in the geo viewer it seems like I’m fighting between Pre-Xform and Xform…I just want to frame my camera using the left/middle/right mouse buttons, but it seems like I’m constantly fighting myself. Any way to just have this camera move affect the main Xform and not the pre-xform (what is that anyways?)

Thanks
Alex

Sorry Rurik, its tough working in there and we are aware that the 3D Viewer needs quite a bit of work. There is no way to keep the camera from populating the pre-xform parameters when using the node viewers, however you might find using a Geometry Viewer pane more helpful.

If you create a second pane and set its type to Geometry Viewer, you can look through any camera using the Camera menu near the top-left of the pane. From there you can then move around freely in the scene without any offsets being applied to the camera’s pre-xform. Once you find a location you’d like your camera to reside in, you can select that camera from the Save to Camera menu and your current viewing position will be applied to the selected camera, in the Xform parameters, not the pre-xform!

Hope that helps

That helps a lot!

Would be great if the geometry manipulation and viewing tools were a bit easier to use. Feels like you need that to be able to really fully use the 3d environment in Touch.

Thanks for the tip, very helpful
