Collada_SaveCams

function Collada_SaveCams(strFileName,T,I,strUnits,strAxisUP)

 

Description: Generate and save a Collada file with all cameras defined by T and I. The collada syntax is based in XML syntax.

In parameters:

  • strFileName = Collada file name (it can include path) to save.
  • Rw2oc = Rotation matrix [mat 3x3xnCams]
  • Twoc = Translation vector (camera position) [X Y Z] [mat nCamsx3] (row based)
  • I : Camera information matrix.  One camera per row.
  • Optional strUnits = Specify the magnitude of Longitude units in collada file. The allowed values are:  ‘Centimeter’, ‘Meter’, ‘Milimeter’. (Default: ‘Centimeter’)
  • Optional strAxisUP = Specify what is the UP axis in collada file. The allowed values are:  ‘Z’, ‘Y’, ‘X’. (Default: ‘Z’)
Example (collada file), it defines 2 cameras with following parameters:

CamID1:

– Pos: [7.071 -7.071 0]

– LookAt: [0 0 0]

– Up vector = +Z [0 0 1]

– xFov = 49.134mm

– Display Aspect Ratio = 16:9

– CCD resolution: 720 x 576

– Inverted image = 0 (NO)

– Original view axis: -1 (-Z)

CamID2:

– Pos: [7.071 7.071 0]

– LookAt: [0 0 0]

– Up vector = +Z [0 0 1]

– xFov = 49.134mm

– Display Aspect Ratio = 16:9

– CCD resolution: 720 x 576

– Inverted image = 0 (NO)

– Original view axis: -1 (-Z)
