Hi, I’ve found gpac and mp4box that was mentioned in the HEIF Apple Developer video.. However it only seems to work with converting video to HEIC still images. It’s also very complex. All I need is a tool that can create an HEIC image and add another image to it as a depth buffer. I’ve tried ImageMagick and libeif that has heif-enc but that can’t add the depth buffer. For such a major knew format I feel I must be missing something here ! Any help appreciated.

Hi, I’m having trouble creating a model from a digitally rendered image, in this case a 3D fractal from Mandelbulber. For a start is this API and example CLI app the most up to date way of doing this ? I also followed these instructions.. Here’s an example of the image I’m using: Overlap is high with only a few degrees between each image, yet I get errors (see below). Any ideas ? Do I need a background behind the object ? Does the util require depth info that the iPhone camera produces ? AFAIK the Apple docs say depth is optional.
