Params List and annotation

params st comment
decimate d decimation factor in range [0..1] to be applied to the input surface before refinement (0 - auto, 1 - disabled)
close-holes ch try to close small holes in the input surface (0 - disabled)
resolution-level rl how many times to scale down the images before mesh refinement
min-resolution mr do not scale images lower than this resolution
outlier-threshold oh threshold used to find and remove outlier face textures (0 - disabled)
cost-smoothness-ratio csr ratio used to adjust the preference for more compact patches (1 - best quality/worst compactness, ~0 - worst quality/best compactness)
global-seam-leveling gsl generate uniform texture patches using global seam leveling
local-seam-leveling lsl generate uniform texture patch borders using local seam leveling
texture-size-multiple tsm texture size should be a multiple of this value (0 - power of two)
patch-packing-heuristic pph specify the heuristic used when deciding where to place a new patch (0 - best fit, 3 - good speed, 100 - best speed)
empty-color ec color used for faces not covered by any image
orthographic-image-resolution oir orthographic image resolution to be generated from the textured mesh - the mesh is expected to be already geo-referenced or at least properly oriented (0 - disabled)

Problem List

  • Pure color as Image
  • Image color of view generated by hsv palette
  • therefor the color of adjacent patch should be very approach
  • mapple remesh to 5W from 12W
    • 20210916231821
  • original 12W
    • 20210916232023
  • As you can see, there are many wrong selected view at the back of lion
    • The blue mesh comes from a view from the bottom
      • 20210916232251 20210916232317
    • The red and purple mesh come from left, the orange mesh comes from right
      • 20210916232524 20210916232825
    • Therefor, those bad choices can be sure that it caused by the normal-vector error when build mesh sureface
