Text to screen

[jonnymaserati]

Hello there!

Is it possible to print text to the screen rather than onto a plane in the scene?

I wish to print some data to the screen, say in the top right, but would like it static and not to move relative to the camera.

I'd like to print data about the end point as it's animated.

Thanks!

How cool is that! :)
You have various options, use a "follower" object which is locked to face the camera (you can make any mesh obj become a follower by adding mesh.followCamera()) or just overlay some text on the rendering window:

from vedo import *

s = Arrow([0,0,1], [1,1,2])

cam = dict(pos=(4.80, -4.56, 3.32),
           focalPoint=(0.186, 0.0532, 1.05),
           viewup=(-0.230, 0.235, 0.944),
           distance=6.90, clippingRange=(4.75, 9.90))
# (press "C" in rendering window to get the above)

axs = Axes(xrange=(-1,1), yrange=(-1,1), zrange=(0,3), yzGrid=0)

vd=Video()
for i in range(100):
    s.rotateZ(3.6).addShadow(z=0)
    msg1 = Text2D("Some welleng data:\n\Lambda = 10 km",
                 pos="top-left", font="VictorMono", c='w', bg='db', alpha=1)
    msg2 = Text("my |\Psi> vector", font="Theemim", italic=1)
    msg2.scale(.075).pos(s.centerOfMass()+[0.2,0,0]).followCamera()
    plt = show(s, msg1, msg2, axs, camera=cam, resetcam=0, interactive=0)
    vd.addFrame()
    plt.remove([msg1, axs], render=False) # need to remove these manually
vd.close()
interactive()

You're a star, especially with that vd=Video() part, that saved me a lot of time!

Do you know if any of the fonts are fixed with (all characters the same width)? Think it'd look nicer if the inc and azi text wasn't jittering so much...

Nice!!
Monospaced are "Calco", "Glasgo", "VictorMono", you may also use "\circ" for deg symbol

Awesome... you're a star!
