    Hi Saki,

     

    Based on what you're saying I believe what you're seeing is the limitations of the Realitycapture 3D viewer.

    The 3D viewer is unable to show the full resolution of your texture model in real-time. It samples it down before it visualizes it, even though the texture quality of your full model is 100%.

    With those parameters you'd expect the cropped model and the full model to be just as sharp. But instead you're seeing that the full model looks blurrier even though it has the same texel size and texture quality.

    To try and test whether this is the case you should use the 'Render' button to generate a high resolution screen capture of your model and save it as a JPG. This screen capture is the actual quality of your model without any visual down-sampling (for performance reasons) within the RC viewer.

    Thanks Mate,

    So simple  :-)        

    A little visually confusing that RC does manage to resolve in viewer at higher texture quality variables, but you're correct,  it's all same/same when output via render.

     

    Prior to your reply..

    I went back to testing new alignments;  Removing a couple less than ideal images, which tightened up the geometry and texture -  Reducing the Optimal texel value from the prior solve, producing 1x 16k texture vs. 9x 16k textures prior  and calculated in 1/10th of the time.  - It's well worth increasing QC of all images prior to alignment!

     

    Additionally I came across another General discussion thread  -  Which I thought worth including here for anyone searching for texture quality wisdom (Looks like you replied to this one too).

    Max # of camera resolves / "Point count" #, "Total projection" #  may look good,  but also seems to increase the % of less than ideal data bring introduced into an alignment / Geometry / Texture solve.

    Tightening up QC of images, reducing (tightening) "Max feature re-projection errors", "Image overlap" and "detector sensitivity" resulted in a 1/3rd reduction of my data set (and likely cache size),  but gave significant bump in texture detail in soft seam areas, with a slight improvement in texture sharpness overall - I'd say a likely improvement to the geometry accuracy too; But that's just me theorising wishfully.

    I'm still not near image sharpness (I'd think there's a way to squeeze a little more out of the images),   but these steps have been good - Thanks for your reply.

     

    Best,

    Saki

    -   I'll tag another painstakingly gathered settings thread, from a more "max data capture" vantage.

    I'm sure methodologies will vary depending on capture.
