I’m curious if there is a way to further compress textures associated with actors when using the ParaView VTKjs export script found here. Please note that I have heavily modified this script for exporting
vtki rendering windows here.
Whenever I export a scene that has a texture, the texture takes up quite a bit of memory and causes the scene to load very slowly in the standalone viewer.
I have some really awesome visualizations I’m trying to share online (see link below) with VTKjs and I’m currently limited to not using the textures because they take far too long to load/take up too much memory in the scene file for websharing.
This same scene has a texture for the topography surface that makes a big difference:
I’ve tried downgrading the resolution of the PNG files I’m using to have a size of about 6.6 MB but the VTKjs scene file has a size of ~144 MB (note that all other data in the scene accounts for ~6-10MB - that’s the size of the scene file with no texture) which means the 6.6 MB PNG file loaded as a texture accounts for ~135 MB in the VTKjs scene file - what’s happening here?
