Re: [osg-users] Antialiasing Text

[Sebastian Messerschmidt]

Hi Roko,

Are you using a true-type font? The default might be a system-font where 
you get no smoothing. Maybe a screenshot would help.

Also, have you tried this without the special character size mode?

Cheers
Sebastian


Hey Glenn,

thank you for your answer : ) - Sadly it barely help, more or less it doesn't 
help at all : (

The fonts still consist of several colors (white and light grays if I specify white as 
the color). How come this is so hard to solve, I think I must do something wrong, 
because, it does not make sense that all people living with this ugly text. I just would 
like to have simple plain text, which has the "properties" either the font 
pixel colored or there is no fonts pixel.

Maybe someone can show me an example how pretty their CharacterSize(10) font 
looks like. Because there must be something wrong that it looks so ugly for me, 
but it's so hard to solve it ^^'


Many thanks guys!

Cheers,
Roko[/img]

Try increasing the texture resolution with
osgText::Text::setFontResolution().

Re: [osg-users] Antialiasing Text

[Roko Talk]

Hi guys,

anyone an idea how I could apply the authors solution without specifying the 
font? 

I just try to have 2D text on top of everything, which should not change it's 
screen size. (<-- 
"setCharacterSizeMode(osgText::Text::OBJECT_COORDS_WITH_MAXIMUM_SCREEN_SIZE_CAPPED_BY_FONT_HEIGHT)")
 

But no matter what I try the text itself looks pretty ugly and I think this is 
caused by anti aliasing. - Do I miss something how I could get 2D text in just 
raw, crystal clear, pixels? So the text either has exactly the color specified 
or there is no text. And what I get right now is, that I specify white as the 
color and the font color is partially white, light grey. 

Anyone an idea? : )

Many thanks in advance!


Cheers,
Roko

Hi Filip,

You can select high res Font to help avoid the undersampling of the
text texture when viewing closely.  See the osgtext example.

Alternatively you could use Text3D as it's polygon based rather than
texture based.

Hi,

How I can implement text without anti-aliasing. If I zoom too close, it looks 
horrible.

Than you,
