    Dear Team

    may you tell the command line that you used to generate the sample Navigation 3d
    all test that i have done failed by my side following the mandatory argument described in the source code.
    thanks for your help

    For instance  :
    OcclusionCalculator -models=C:ImaginationPowerVRGraphicsSDKSDK_3.0ExamplesAdvancedNavigation3Dtemp -index=modelindex.nav -near=1 -far=1000 -subdivx=2  -subdivy=2  -subdivz=2 -camera=cameratrack.pod -pathsteps=2 
    -o=test
    but what is the subdivx ,y,z and what is the exact meaning of pathstep ( is it per city block ? )
    thanks in advance

    Hi David,

    the example command line is a bit misleading. The occlusion calculator is able to run in two different modes:
     – in the first mode it uses a regular spatial subdivision and the degree of the subdivision is configurable via the command line (-subdivx/y/z)
     – in the second mode the occlusion data is generated along a camera path; the number of subdivisions along the path is configurable with “-pathsteps”

    It can only run in one of the modes at a time. In your example it uses the camera path for occlusion data generation.

    Regards,
    Marco

    Thanks alot for your answer 

    The application is now generating 10.7 MB  mega  * 24,
    I though that  i will get only an occlusion.nav FILE.
     

    the name of the files are prfiexd with  : tilemap_CM_US_IL_CHICAGO_008_015_L.DAE.pod …
    and 
    my command line is 

    OcclusionCalculator -models=C:ImaginationPowerVRGraphicsSDKSDK_3.0ExamplesAdvancedNavigation3Dtemp -index=modelindex.nav -near=1 -far=1000 -camera=cameratrack.pod -pathsteps=2 -o=test 
    do you have any idea why i dont have my occlusiondata.nav ?
    thanks i am fighting with this  things.
