Hi everyone,

I find it extremely useful, when my 3d locators in my 3d app (in my case 3ds Max) have the same color as the trackers in Syntheyes.
And as the standard SynthEyes exporters do not export tracker colors, I thought it could be helpful to share the way how to do it yourself Wink
It just needs a little tweaking of the exporter scripts.
But... it can be a little tricky depending on your 3d app and the way it handles colors of locators.

For 3ds Max its kinda straight forward, as you can assign every helper a individual RGB color.

This is how you convert sizzle's 24bit color to RGB. (I think most 3d apps use RGB)


Code:
 
      rgb_r = (tk.color & 255)
      rgb_g = (tk.color >> 8 & 255)
      rgb_b = (tk.color >> 16 )
      


then, after the tracker has been created, change its wire color to the 2d trackers color

Here a example for 3ds max:

Code:

// This is the creation of the helper in the original script
//////////////////////////////////////////////////////////////////////////////
printf("newtk = Point name:\"%s\" pos:[%lf,%lf,%lf] size:%lf "
      "axistripod:off centermarker:on isSelected:on\n",
      tk.nm, tk.wx, tk.wy, tk.wz, trackerSize*wsize)
//////////////////////////////////////////////////////////////////////////////

//Convert its color to RGB

      rgb_r = (tk.color & 255)
      rgb_g = (tk.color >> 8 & 255)
      rgb_b = (tk.color >> 16 )

//Change locator's color to the color of 2d tracker form SynthEyes.

      printf("$.wirecolor = [%ld ,%ld ,%ld] \n",rgb_r ,rgb_g ,rgb_b )



I guess it gets kinda tricky for Maya, as Maya's locators do not have individual colors.

Just 8 predefined colors can be assigned. As far as i know.

If someone knows a cool way to work around this problem please let me know.

I hope this helps a little,

Damian

heh, about colors

I was always wondering how sizzle's 24bit color value relates to RGB values.
I'm everything but a coding or scripting type of guy and the sizzle's color value was something totally mysterious for me and far beyond my understanding... I didn't ask anyone, asking's lame, nothing beats the feeling after figuring out some crap yourself hehe Very Happy

And today I finally cracked it!
tk.color = red+green*256+blue*65536
I still don't have a clue why is it so, I just figured it out by scrutinizing the values that sizzle gives me after manually assigning various RGB values to trackers on tracker panel....

Very Happy
