MeshLab - Decimating a model




  • Avatar

    Thanks James for the article - this helped me successfully to reduce my image size - however a couple of pointers for anyone else wishing to reduce the file sizes for uploading to Sketchfab and avoid the minor difficulties I encountered :-

    1. the version of Meshlab you used is Meshlab_64bitv1.3.3 - the latest version is Meshlab 2016.12 and the menu entries are slightly different, which initially stumped me - as there is no entry in Meshlab 2016.12 of

    "Filters → Remeshing, Simplification and Reconstruction → Quadric Edge Collapse Decimation (with texture)" 

    the menu entry is

    "Filters → Remeshing, Simplification and Reconstruction → Simplication : Quadric Edge Collapse Decimation (with texture)"

    which isn't a simplication if you are looking for a menu entry beginning with Q .... !

    When saving my model as an obj the file size reduced from a dae at 74+ MB to an obj at 26+ MB with the creation of an .obj.mtl config file. The mtl file references the original texture file  used by my dae model - which was a png file of 49+ MB. I converted the texture.png to texture.jpg which was only 3+ MB and edited the .mtl file to refer to texture.jpg. So a total change in data size - model + texture from 120+ MB to 30+ MB

    Thanks for letting me know! I'll find some time to update this page with more recent screenshots and menu entries.
