# Generate 2d image from image3d object

I have created a image3d from which I have rotated it to create a rotating view of the object. I want to be able to render each 'frame' to a 2d image so that I can export the frame sequence to create a video using Export. Can anyone help me please?

Many thanks in advance

• Take a look at Rasterize

• Would you please include an example of the code you are using to rotate the Image3D? Feb 25, 2015 at 23:45

You can use Rasterize[plot,"Image"] on each frame as paw suggested.

img = Image3D[RandomReal[1, {5, 10, 10}]]

imageList =
Most@ParallelTable[
Rasterize[
Image3D[img,
ViewPoint -> {2.5 Cos[θ], 2.5 Sin[θ], 2},
ViewAngle -> 30 Degree], "Image"], {θ, 0, 2 Pi, 0.01 Pi}];
ListAnimate[imageList]

Export["animation.avi", imageList];
Export["animation.gif", imageList];


However, Export already handles animations natively! (Although not for .gif sadly.)

animation =
Animate[Image3D[img,
ViewPoint -> {2.5 Cos[θ], 2.5 Sin[θ], 2},
ViewAngle -> 30 Degree], {θ, 0, 2 Pi}]

Export["animation.avi", animation];

• Thank you, the above code is exactly what I was after, I had been playing with Rasterize, but I hadn't quite hit the mark. Feb 26, 2015 at 13:00
