Why can't you see my script? It was in my email reply to the group. You can also see it in the forum here: http://forum.openscad.org/Another-missing-feature-All-I-want-for-Xmas-tp30314p30351.html You can use $vpd with scale() to set the size of the text as I did in my example. You have to enter the window size in pixels at the start of my screen, copied from the GUI status line. I attempt to relate them to the camera with $vpf but my calculation is not quite right.

This is a more correct version but it always looks like the text is center justified but it isn't. Not sure what I got wrong. window = [776, 362]; // Copied from the bottom of the GUI sphere(20); translate($vpt) rotate($vpr) scale($vpd / window.y) translate([window.x, -window.y] / 2 * tan($vpf)) linear_extrude(0.001) text("hello", valign = "baseline", halign = "right"); On Sun, 25 Oct 2020 at 05:40, nop head <nop.head@gmail.com> wrote: > Why can't you see my script?

It seems to be random. So if you really want to be sure that you can read all the posts you have to go to http://forum.openscad.org/! Strange but is like this

OK this is a version that works. window = [737, 888]; // Copied from the bottom of the GUI sphere(20); translate($vpt) rotate($vpr) translate([$vpd * window.x / window.y, -$vpd] * tan($vpf / 2)) scale($vpd / window.y) linear_extrude(0.001) text("hello", valign = "baseline", halign = "right"); On Sun, 25 Oct 2020 at 06:05, nop head <nop.head@gmail.com> wrote: > This is a more correct version but it always looks like the text is center > justified but it isn't.

Slightly more concise: window = [737, 888]; // Copied from the bottom of the GUI sphere(20); translate($vpt) rotate($vpr) translate([window.x / window.y, -1] * $vpd * tan($vpf / 2)) scale($vpd / window.y) linear_extrude(0.001) text("hello", valign = "baseline", halign = "right"); The window pixel dimensions are needed for two reasons. 1) to get the correct x offset that depends on the aspect ratio and 2) to scale the text if you don't want its size to change when the window is resized. So we need yet another $ variable, $vpw to be the window size in pixels.

Some internet providers are less friendly to mailing-lists. You can also get a Digest semi-daily too, which should have all the posts.

The above reply was to Michael@Oz, but for some reason it shows dpa instead. -- Sent from: http://forum.openscad.org/

Does the latest code I posted work for you?

Slightly more concise... Looks interesting. Will try it out. -- Sent from: http://forum.openscad.org/
