fluid text moving

Scripting Issues
1

Hi to everybody :slight_smile:

I’m developing a panda project for visual training.
The “game” is simple: a text that is moving on the screen (linear moving) and a user that should be able to read the word.
The problem is that if the text moving a little bit faster the word become unreadable or blurred.

This is my little example:

import direct.directbase.DirectStart
from direct.gui.DirectGui import *
from direct.interval.LerpInterval import LerpPosInterval

text = OnscreenText(text = “myText”,pos = (-1.7,0,0),scale = (0.05,0.1,0.1),fg=(1,1,1,1))
base.setFrameRateMeter(True)
i = LerpPosInterval(text,2,(2.7,0,0),fluid = 0)
i.start()
run()

I checked and graphics driver is correctly installed, panda3d works on 60fps and the problem is the same in an other pc.

I’m on ubuntu 12.04 and i tested my app also in a windows 7 pc.

Anyone have suggestion to avoid this problem? thanks!

I don’t think that this is caused by Panda. If I make a screenshot while it’s moving, it appears perfectly still in the screenshot.

It seems more likely that this is simply inherent to the way monitors display rapidly moving content, or inherent to the way the eyes perceive motion.

I’m not sure how this can be solved, sorry.
