This value is mapped into a gray shade according to this formula
|
||
|
|
|
||
|
|
v=clamp(v,LowPass,HighPass)
|
||
|
|
v=(v-LowPass)/(HighPass-LowPass)
|
||
|
|
graylevel=GammaCorrection(v,GammaLev)

|
keys
|
||
|
|
|
||
|
|
'c' compute the sampling (sample are added so pressing c twice is the same of using 2n sampling directions)
|
||
|
|
'S' save a ply with the currently computed color.
|
||
|
|
's' smooth (average) the computed visibility
|
||
|
|
' ' add the current view to the sampling direction
|
||
|
|
|
||
|
|
'l' Increase LowPass
|
||
|
|
'L' Decrease LowPass
|
||
|
|
'h' Increase HighPass
|
||
|
|
'H' Decrease HighPass
|
||
|
|
'g' Increase GammaLev
|
||
|
|
'G' Decrease GammaLev
|
||
|
|
|
||
|
|
'a' Toggle Lighting
|
||
|
|
'A' Toggle per vertex coloring

options
|
||
|
|
|
||
|
|
-n <number> set the number of sampling direction (default 32, but 100~1000 should be better)
|
||
|
|
-f flip normal of the surface
|
||
|
|
-z <float> specify the z tolerance used to decide if a vertex is visible against the zbuffer or not (default 1e-4, useful range 1e-3 .. 1e-6)
