Animated Network Background Image

I created a little script to update Network Background images
using houdini`s timeline callback , just create a new shelf tool and copy and paste my code
this tool works as toggle mode . click to activate , click again to deactivate

Code :

       




import hou 
chrysl666BG_padding = 0 

#CREATE BG
def updateBG(event_type,frame):
    #create initial vars 
    imagePath=""
    strFrame = str(frame)

    
    #get editor and BGimage infos
    editorHolder = hou.ui.paneTabOfType(hou.paneTabType.NetworkEditor)
    BGLIST = editorHolder.backgroundImages()
    
    #if BG image is not created  -- do create
    if(len(BGLIST) < 1 ):
        #start holders
        imageHolder = hou.NetworkImage()
        imagePath = hou.ui.selectFile(start_directory="HIP" , title = "SELECT FRAMES ")
        # check padzeros
        pathParse = imagePath.rsplit(".",2)        
        if( len(pathParse[1]) > 2 ):
            global chrysl666BG_padding
            chrysl666BG_padding  = int(pathParse[1][2])
            strFrame = str(frame).zfill(chrysl666BG_padding) # apply padding
        # build path string 
        newPath = pathParse[0]+"."+strFrame+"."+pathParse[2]
        # apply Background Image 
        imageHolder.setPath(newPath)
        imageHolder.setRect(hou.BoundingRect(0, 0, 5, 5))
        editorHolder.setBackgroundImages([imageHolder])
    else: # BG image is already created 
        #starts holders
        imageHolder = BGLIST[0]
        imagePath = imageHolder.path()
        #chack padzeros
        pathParse = imagePath.rsplit(".",2)
        #padding  = len(pathParse[1])
        global chrysl666BG_padding
        strFrame = str(frame).zfill(chrysl666BG_padding) # apply padding
        # build path string 
        newPath = pathParse[0]+"."+strFrame+"."+pathParse[2]
        # apply Background Image 
        imageHolder.setPath(newPath)
        editorHolder.setBackgroundImages([imageHolder])
        

#check for playbar events when tool is clicked 
events =  hou.playbar.eventCallbacks() 
if(len(events) <1):
    #if not events, create it
    updateBG(0,hou.intFrame())
    hou.ui.displayMessage("BG IMAGE CREATED")
    hou.playbar.addEventCallback(updateBG)
else:
    # events exist  delete it
    hou.playbar.clearEventCallbacks()   
    hou.ui.displayMessage("BG IMAGE EVENT DELETED")






       
 

Pos Fix Qt install

after install Qt in linux  you need  fix some errors using libs

using GCC 6.3 in Centos 7 -- HOUDINI HDK

Centos7 comes with gcc 4.8
but Houdini 17 needs gcc 6.3 at least

so you need install a update version
and left old version only for the system general uses
you will need  SCL package manager  and GCC 6.3 dev toolset

Write down in terminal :

sudo yum -y install centos-release-scl
sudo yum -y install devtoolset-6

then to compiling using hcustom and this new dev toolset
just send commands by scl
lets go compile geoisosphere from HDK samples :

scl enable devtoolset-6 "hcustom -s geoisosurface.C"

output :

Making geoisosurface.o from geoisosurface.C
Making ./geoisosurface from geoisosurface.o
g++ geoisosurface.o -lpthread -o ./geoisosurface -L /opt/hfs17.0.352/dsolib -lHoudiniUI -lHoudiniOPZ -lHoudiniOP4 -lHoudiniUSD -lHoudiniOP3 -lHoudiniOP2 -lHoudiniOP1 -lHoudiniSIM -lHoudiniGEO -lHoudiniPRM -lHoudiniUT -lhboost_system -L/usr/X11R6/lib64 -L/usr/X11R6/lib -lGL -lX11 -lXext -lXi -ldl -Wl,-rpath,/opt/hfs17.0.352/dsolib


done!
