load full res scene after "load"

hi all
hope you had a great new year (it's the 15th already)

i understand that
PRELOAD
loads the pano before blend
and seen some actions to preload entire tour (but its 150 panos.. a lot to load before walking and may be not visiting)

is there a way to load it after blend/loadscene?

so a visitor arrives from 1 place to other and all the visible squares are loading for that resolution
is it possible to load all the non visible suqares in the same resolution?
so when he loos around the full res is already there

thank you all

yes, I wrote myself a preloader plugin. it works in several modes:
- loading of all panoramas before the start of the tour
- loading neighboring panoramas in the background while the visitor is watching the current one (it checks which panoramas can be switched from the current one and loads them) *cool*

You can use regular expressions to match key values in the xml string of the scenes. Then preload the images by creating the image object or the fetch method. If you want more control, you can also load previews and level tiles in groups. This way you can control how much you need to preload. ;-)

If so many people are interested in this preload plugin, I can make one in 3-4 days. The image paths are automatically parsed and preloaded. No configuration is required. *huh*

@Eric Chen,

I'm not sure if i would use such but i'm interested how this works and looks in code. I would also like to see what is the difference and what the limits are, data load wise etc
Would you be so kind to share it open source? Maybe some more people want to see the code to learn and we can collect some money together to get you some?

my particular case is

i have a path to go to and some jumps are automatic to show the visitor the path. Think as you go from 1 room to the other and you have a corridor that has no interest... just to go through it so you feel the path.

If the corridor has a bend and in the corner , after the load, i call a lookto(somewhere) . This lookto does not load the rest of the pano and you go from the initial view, which has loaded a normal res, to another view which has only the "preview" image jumping from a normal res to a very-low-res.

the idea was, after the load, to load the "normal res pano" (might be a normal or a multires) after the "loadscnee" to the "very low res" would never appear

i'm ok with some contribution because this will increase the quality of my tours

thank you all

Ok, I'll open source this perload plug-in. I think I'll probably upload it to Github. Guys, I'm more looking forward to a remote job than a donation. *g*

Hey guys, here is the source code of the preload plugin. I haven't prepared the documentation, but there are necessary comments in the preload.xml. *smile*

tx eric, very nice of you to share it !
for tours without too many scenes it makes a lot of sense to use this.

For too many scenes, or very large resolution panos, limiting the maximum preload level is a wise choice. We don't need to preload all the levels. Preloading the preview and level 1 are generally sufficient.

good morning!

Quoted from "herrpedro"


the idea was, after the load, to load the "normal res pano" (might be a normal or a multires) after the "loadscnee" to the "very low res" would never appear
thank you all


from initial post ->
"and seen some actions to preload entire tour (but its 150 panos.. a lot to load before walking and may be not visiting)
is there a way to load it after blend/loadscene?"
"

either way I'm a sw developer (in other area) and i value testing
I added it to the tour i'm working on and it loads the whole tour on the beginning and not "behind the scenes".
Didnt find the place where you added it to work.. may be an event that i could not find

by testing the functionality i tried to add more levels but i don't think its working for multilevel since the placeholders are not solved
regular panos preload ok

the url in the browser console looks like ->
2022_10_11_14_19_23_DSC02508_HDR_Panorama.tiles/l2_b_%0v_%0h.jpg

thank you for your (fast) work

i think "%0v" and "%0h" is not covered... this should be solvable.

You should be able to see the “preloading_page” layer in preload.xml. You can hide this layer.

2022_10_11_14_19_23_DSC02508_HDR_Panorama.tiles/l2_b_%0v_%0h.jpg

It is currently matched with the default placeholder.

panos/a3.tiles/%s/l%l/%v/l%l_%s_%v_%h.jpg

You can make placeholder changes in preload.js, depending on your situation.
