A SCNTechnique chapter with example of a multipass technique

[matteococon]

Hi
Thank you of your very clean book with a high quality material so well described.

I can't find in internet a full working example of multi pass technique using SCNTechnique and today I've seen that it's not covered in you book.

I'm wondering if you are planning to explore that argument in a next update.

Yes, I plan on covering it a future update. Multi pass techniques is one of the new additions that I've been most excited about. I still need to experiment with it some more and find one or two suitable examples.

I would want to cover shader modifiers first, so it won't happen in the first update. Then, it would be a choice between skinning + morphing, physics, or multi pass techniques. I'm currently thinking that skinning + morphing should come first. But I haven't decided between physics and techniques. That decision would mostly depend on what people want to read about.

Hi d-ronnqvist,
great book - thank you. I was wondering whether there is an update on this topic, or is it still on the drawing board?

I think this is the best update that I can give you: the plan is still the same, but there hasn't been any progress for a year.

Shortly after the initial release, I burnt out. Since then I've taken time to recover* and reflect. Recently, I started looking at these chapters again, but at a very different pace (that I believe I can maintain while doing my day job and living a life ;)). I don't know yet how fast or how frequently I will be able to release new chapters this way, but my plan is to do it.

I read your blog after posting. I've been there and completely feel your pain. Take your time. No rush from me at all.

Your book isn't just a great SceneKit book, its a great 3D book and a great example of an iBook. I have a large scale personal project as well feel pretty burnt out about it. What I do is insert small chunks of work on it into my diary that have achievable and small targets. I don't know what will work for you, but I do know that you have a head start on an incredibly valuable product that only becomes more valuable as SceneKit gets developed and starts to become a core part of whatever gaming, VR and AR projects Apple has in the works.
