Animation

Example of Successive Animation:

import os
from time import sleep

import salome

import VISU
from visu_gui import *

# The directory containing MED files
datadir = os.getenv("DATA_DIR")

# Import a MED file 
medFile = os.path.join(datadir,"MedFiles","TimeStamps.med")
myResult = myVisu.ImportFile(medFile)

# Create a 3D view
myViewManager = myVisu.GetViewManager()
myView = myViewManager.Create3DView()
myView.SetTitle("Animation view")

# Create an animation instance
fieldName = "vitesse"

myAnimation = myVisu.CreateAnimation(myView);

# Set the successive animation mode
myAnimation.setAnimationMode(VISU.Animation.SUCCESSIVE)

# Set the animation properties:

# Add a field with timestamps, on which the animation will be performed
fieldName = "vitesse, m/s"
fieldSO = salome.myStudy.FindObject(fieldName)
myAnimation.addField(fieldSO)

# Set the presentation type for the first field
myAnimation.setPresentationType(0, VISU.TDEFORMEDSHAPEANDSCALARMAP)

# Generate presentations
myAnimation.generatePresentations(0)

# Create the pattern of a Deformed Shape and Scalar Map presentation
meshName = "dom"
fieldName = "vitesse"
fieldEntity = VISU.NODE
timestampId = 1
myDefShapeScalarMap = myVisu.DeformedShapeAndScalarMapOnField(myResult, meshName, fieldEntity, fieldName, timestampId)
myDefShapeScalarMap.SetScale(0.75)

# Apply the pattern properties to all generated presentations
myAnimation.ApplyProperties(0, myDefShapeScalarMap)

# Generate frames
myAnimation.generateFrames()

# Publish the animation object in the study
myAnimation.publishInStudy()

# Set the speed
myAnimation.setSpeed(80)

# Save the animation after changing the speed
myAnimation.saveAnimation()

# Fit All
myView.FitAll()

# Start the animation
myAnimation.startAnimation()

# Rewind to the first frame
sleep(10)
myAnimation.firstFrame()

# Update the object browser
salome.sg.updateObjBrowser(1)

Example of Parallel Animation:

import os
from time import sleep

import salome

import VISU
from visu_gui import *

# The directory containing MED files
datadir = os.getenv("DATA_DIR")

# Import a MED file 
medFile = os.path.join(datadir,"MedFiles","TimeStamps.med")
myResult = myVisu.ImportFile(medFile)

# Create a 3D view
myViewManager = myVisu.GetViewManager()
myView = myViewManager.Create3DView()
myView.SetTitle("Animation view")

# Create an animation instance
fieldName = "vitesse"

myAnimation = myVisu.CreateAnimation(myView);

# Set the successive animation mode
myAnimation.setAnimationMode(VISU.Animation.PARALLEL)

# Set animation properties:

# Add two fields with timestamps, on which the animation will be performed
fieldName1 = "vitesse, m/s"
fieldSO1 = salome.myStudy.FindObject(fieldName1)
fieldName2 = "temperature, K"
fieldSO2 = salome.myStudy.FindObject(fieldName2)

myAnimation.addField(fieldSO1)
myAnimation.addField(fieldSO2)

# Set the presentation type for the first field
myAnimation.setPresentationType(0, VISU.TVECTORS)

# Set the presentation type for the second field
myAnimation.setPresentationType(1, VISU.TSCALARMAP)

# Generate presentations for all fields
nbFileds = myAnimation.getNbFields()
for i in range(0, nbFileds):
    myAnimation.generatePresentations(i)

# Create the pattern of Vectors presentation
meshName = "dom"
fieldName = "vitesse"
fieldEntity = VISU.NODE
timestampId = 1
myVectors = myVisu.VectorsOnField(myResult, meshName, fieldEntity, fieldName, timestampId)
myVectors.SetScale(1)
myVectors.ShowColored(True)

# Apply the vectors pattern properties to all presentations generated for 'vitesse' field
myAnimation.ApplyProperties(0, myVectors)

# Generate frames
myAnimation.generateFrames()

# Publish the animation object in the study
myAnimation.publishInStudy()

# Set the speed
myAnimation.setSpeed(95)

# Fit All
myView.FitAll()

# Start the animation
myAnimation.startAnimation()

# Update the object browser
salome.sg.updateObjBrowser(1)
