Flag images for texturing.
« on: July 22, 2011, 02:35:39 AM »
be a good feature to be able to flag certain images to be or not be used in the texture map generation.
example: I'm using 6 cameras for facial performance capture, 4 of the cameras are b/w cams, used only
for geometry creation, but I would like to flag the other 2 color cameras to just be used for texture creation.

Hello Andy,

You can disable b/w photos in the Workspace pane and build texture using only enabled photos in chunk (building texture procedure take in account only enabled photos).

I'm curious about the use of black and white images for reconstruction.    Does it make feature detection harder because color can't be used to differentiate one point from another?  Or does it reduce error because there is no confusion caused by variations in color between frames?

Hello Ian,

Feature detection doesn't depend on color. Using black&white photos for geometry reconstruction usually gives similar results as for color photos, but in some cases quality of black&white reconstruction could be slightly worse.
