Preloading Textures in start.cel

[haukew]

Hello!
I am using the 64k-Surface-Map of the Earth posted by FightSpit as my default-texture for the Earth. In my start.cel is defined, that the camera shall fly directly to the Earth, which causes lags - obviously because the texture is so big.
How can i preload a virtual texture in a .cel-script? i tried using the absolute path , the path from the celestia-directory and i tried just to give the name of the 2 main png's. Nothing worked, the lag is still there.

Thanks in advance, Hauke

I am not an expert of script but I repeat again this addon need a fast computer because of big textures.

About your problem I think you should change the distance from earth in start.cel to load only the two textures (tx_0_0 and tx_1_0).
Here the original code:

Code: Select all

 
select {object "Sol/Earth"}
  follow {}
  goto   {time 3.0  distance 6.0}
  wait   {duration 2.0}


Try to change the distance > 6.0 (10 or 15 for exemple but I am not sure, if someone can confirm me ?)
If this method can solve your problem, try to download the 32K or 16k of Earth made by others autors.

Bye!

Hello!
Thanks for your reply, i think my computer should be fast enough (Athlon3000+, GeForce FX 5900, 512 MB Ram) or isn't it?
The lag isn't too big (about half a second), though it would be great if it happened when the camera isn't moving.
Isn't it even possible to load the textures on celestia startup? a long startup (half a second longer...) is ok for me as long as it doesn't lag
Your solution would only make the camera zoom not-so-far-in-that-the-texture-isnt loaded, right?

My problem is, it lags already when the 1st Earth-texture is loaded, so about 4.000.000 km from earth, so a preload to make it lag half a second when camera isnt moving would be greatly apreaciated...

Thanks in advance, Hauke

How can i preload a virtual texture in a .cel-script?

VTs are used to avoid loading a complete texture. So you can't preload it - and you probably wouldn't want to anyway (take a look at the size of the VT on your HD - do you really want Celestia to load the whole thing?).
