General / Gradual Selection Order?

« on: June 18, 2024, 05:00:31 PM »

I've seen 2 different opinions on the order of the various Gradual Selection processes and was curious if anyone had any thoughts or reasoning between them.

One method is:
1. Reconstruction Uncertainty
2. Reprojection Error
3. Projection Accuracy

and the other flips the last two steps:
1. Reconstruction Uncertainty
2. Projection Accuracy
3. Reprojection Error

General / Texture Quality - what affects this?

« on: June 11, 2024, 06:45:15 PM »

I'm wondering if the camera angle relative to the subject (and thus to the resulting normal of the constructed face(s)) makes a significant difference in the quality of the pixels that get mapped onto that face.

Like if you took photos at 90 degrees to the surface of, say, a wall, and modeled that, but then also repeated the process but angled the camera at some angle other than 90 to the surface (say, 70 or 60 degrees) - does the software do more interpolating of the texturing pixels as the camera angle (relative to the face) moves away from 90 degrees?

I'm just trying to get a sense of how the textures get mapped to the faces, and how to optimize that process during the shoot.

General / Decimating and Smoothing

Is there a preference between the order of these operations? I feel like you would smooth the high-face model first, then decimate the smoothed model... but I also have no idea what I'm doing.

General / What is "Adaptive camera model fitting" doing?

« on: May 16, 2024, 07:40:16 PM »

I've seen tutorials where people use this rather than the default settings in the dialog (the various fit parameters). When is it approriate to use one over the other?
