Interactive Images are a great export option within
Visualize Professional, allowing you to view the model in a series of 360
orbital spins within a web browser.
However, what happens if I want to use this interactive
method to demonstrate a mechanism or animation instead?
By utilising this method, we can allow users to
interactively play through their animation by simply scrolling across the
screen, reversing and focusing upon any chosen element of the sequence.
Click and drag left to right to play animation - This is a large file, it may not load immediately
So how can we create this interactive and immersive content?
is by combining both the exports of an animation and an Interactive Image.
First, let us focus upon creating the Interactive Image.
An interactive image is a collection of rendered images
that are viewed and controlled within a html file.
In this instance, we simply want to create a placeholder for
the stills from the animation. Choose Interactive Image under the Output Mode
and select a single orbit. This will create only a single spin around the
model, however the number of images will be the number of stills created in our
So for my example, I will be rendering out a 10 second long
animation at 30 frames per second.
This simply is 30 x 10, so simply 300 Images per Orbit
Render this at Preview mode, at the same resolution as the
Animation. We will be removing the still images and replacing them with the
animation images instead.
Creating the Animation
Export the animation as individual frames by unselecting the
Create Movie checkbox. I would also recommend naming the file Frame, for ease
of compiling both the animation and Interactive Image in the next step.
Animation and the Interactive Image
This is where the magic happens, we are going to replace the
images within the Interactive Image with our animation instead!
Find the Image sub-folder within the Interactive Image and
you will see the individual still with a sequential naming sequence. Delete all
of these images an instead paste in your rendered stills from your animation.
You will notice that the files from the animation have a
slightly different naming structure, Frame_0001 rather than Frame000001. We
will need to change this behind the scenes.
Find the JS folder inside data, to reveal the hidden away
Right click upon threesixty.js and choose to edit within
You will see the naming structure Frame#####.jpg listed.
Change this to Frame_####.jpg
This will change the naming structure to the files within
the Images folder.
If you didn’t save your animation still as Frame, we can
easily tweak the name here. Simply remove Frame and change to the new filename
– don’t forget to leave the Hash symbols (#) in to denote the numbers at the
Open the Interactive Image backup from the Open.html file
and view your work!
Want to fine tune your interaction with the model?
Edit the vr.js file and edit the ‘InfiniteAxis’ to read
This will prevent the animation looping and going back to the
Change the ‘Grabbable’ values to alter how far you need to drag your mouse to
play through the animation.
The ‘ThrowDuration’ allows you alter the inertia and how long the effect
continues after you have released your mouse.
