I'm very new to meshlab and am not much of a programmer, so this is a shot in the dark.

I have a 3D model of the inside of a very intricate building with many 3D sculptures. Around 2000 photos were taken to create this 3D model. Right now there are about 6 million vertices and 12 million faces. I need to drastically cut down on the number of triangles in the model, without compromising on all of the colors/patterns (texture?). I've been told there should be a way to reduce the amount of triangles and then adding the colors back onto the surface as a texture. Or at least on flat surfaces, the amount of triangles can be drastically decreased, and then afterwards you should be able to slap on a texture of the original colors.

I've looked in the filters > texture menu, but I can't seem to figure out what to do. Any help would be greatly appreciated.

What you need is mesh simplification, the tool is in:
Filters -> Remeshing, Simplification and Reconstruction ->
Simplification: Quadric Edge Collapse Decimation (with texture)
