GDL: Request viewing angle in Section/Elevation

[runxel]

In 3D we can already request the viewing angle so that billboards can be rotated into the right view towards the user.

We need the same thing for sections and elevations.

What do we need that for:

• billboards that work everywhere
• hiding/showing details depending on the view direction (e.g. think of doorframes which look horrible in sections > 1:50 where the door is not perpendicular to the viewing direction)
• etc.

Yeah, absolutely, I have been asking for this for years!

It is crazy to me that billboard trees and people can turn towards the camera in 3D but not in elevations...

"It is crazy to me that billboard trees and people can turn towards the camera in 3D but not in elevations..."

I totally agree.

The direction (rotation) of the elevation line would give the camera angle required.

So it is not as if there is anything that would need to be done as in setting the camera angle.
