Animation is a video that is produced by a series of images. In the old times, animators used to draw these images by hand. In our days, PCs with special software produces these images (render). I made my images for my animations mostly with DAZ Studio and 3D Max and then I edited them in Adobe After Effects.
I have used many of them for my promos in many 3D products of DAZ 3D.
