[Plib-users] ssgaSky and Scaling ofthe scene

[Michael W. <mic...@ti...>]

Hi all,
I am using ssgSky to build the sky in my simulation. I have build it from
the sky-example of plib.
My problem is now:
The scene is build in the dimension 'kilometer' and the sky and his objects
in demension 'meter'. The sky looks very good. But my airplane never can fly
over the clouds.
If I reduce the scaling of the sky and his objects to the dimension
'kilometer' the clouds come to near and not scattered.

How can I combine the dimension 'kilometer' in the scene with the dimension
'meter' of the sky ?

Michael

What are your sky settings ?

Example:
sky->build(80000, 80000, nplanets, planet_data, nstars, star_data);
sky->addCloud(*"data/scattered.rgba"*, /// texture
/              80000,                 /// span
/              3000,                  /// elevation,
/              100,                   /// thickness
/              100);                  /// transition

/I assume you have reduced the h_radius & v_radius parameters for build(),
thus have you also reduced the addCloud() 'span' parameter ?

Cheers,
Nick

Hi Nick,

I have multiplied all sky and clouds parameter with 0.001,alo the span
parameter. .

I have found in the source for building the clouds the parameter scale =
4000.
Do you know what it's mean.

 Best regards

Michael
