What can a bunch of creative Swiss do with a photogrammetry castle model?

Each month we have a meetup called 3D Thursday here in Lausanne. We gather and have a nice “Apéro”, followed by a presentation on a theme related to 3D or Computer graphics in general.

In March the theme was Photogrammetry using a drone. Our presenter Thierry used a DJI and Photoscan 3D to produce a very interesting .obj model + texture of the castle of Vufflens-le-Chateau (making-of here in french) .

For April I proposed to our members to use the data (you can get it here) to create something, a render, a matte painting, an anim, a game or whatever they want and show it at our April session.

I was afraid that we would not have enough material to show or talk for an hour, but oh man was I wrong. Everyone (I love you guys) made something, that is amazing. As you can see we have many different users, backgrounds and styles !

So here are the results in no particular order.

so now that you are inspired…. download the data here or there and also create something fun !

3D Nature shots

This summer we had an interesting opportunity at work to create some nature scenes. Check the movie at the end of the article

Nature Shots

The type of nature we were looking for is the karstic jurassic scenes of Jura (not sure about the geological correctness of it). We created 3 sets of shots, a blueish one, another yellowish, and finally a night shot. In the end we edited them nicely so we do not feel too much the differences.

We used those shots as background and integrated the images and footages provided by the client. Here are few examples of end result (using open movies content as placeholders).

examples

We managed to create a nice 2 minutes movie of nature background and front content from the client. As usual the trick to manage all those shots in only a few days, was to create a small library of assets that we could reuse. Those included stones, rocks, trees, pine trees, leaves, plants and flowers (all plants were just 2d planes) and more low-res rocks

The movie was used internally so we can not show the company’s content, but instead I made a small edit of just the 3D Scenes, including a small “behind the scenes” sequence.

Here is the result (Edit of only the 3D scenes)

 

 

Create a sci-fi image in one hour, and why I could do it.

This week I was browsing the web when I fell on an image that struck me. As usual the image was downloaded and put in my “inspiration” folder, a place where there are all sort of stuff that must be checked back later , either to analyze, study from, get inspired or maybe try to recreate a similar atmosphere or effect depicted in that image. The image can be found here : www.connector3d.com (made by moth3r.com)

So yesterday I had some free time and I wanted to redo this strong contrasted image, of a pure white light illuminating a kind of spaceship dock or bay. Here is the image that took me around one hour to create (not counting rendering 20mins)

As you can see this is fairly detailed and that is the point I want to focus on today :reusing pre-modeled greebles freely available.

Here is the quick process creating this image :

Screen Shot 2015-05-23 at 19.30.08First I block some basic shapes (very classic in itself, the aim of exercise was more of lighting). I could have gone more hexagonal, or with stronger silhouette.

Then I remembered having seen some pretty good greeble blend swap file.  Here is the file (http://www.blendswap.com/blends/view/45973), and once again it is done by Kuhnindustries, who is an amazing modeler!

Screen Shot 2015-05-23 at 19.31.51

I do believe those kind of blendswaps are the most useful ones. Small elements that you can reuse and assemble in a bigger set/model/scene, just like Lego bricks. If you know of some other ones feel free to comment below, I will add them here

So again thanks Kuhnindustries for all your models! If you ever meet me, you get a few free drinks 🙂

p.s. Someone on Twitter rightfully mentionned that this image has no real Point of Interest. In fact the original image had some text in the center, so here is an updated version, with something to look at 🙂

A journey through Architecture and Openworked Creations

Finally there is some interesting commercial project worth mentioning on the blog : “A journey through Architecture and Openworked Creations” , for swiss watch manufacturer Vacheron Constantin .

4images

Openworked technique known in french as “skeleton” , is the art of opening the watch movement so that one can see through it.

here is the movie :

We had to create 3 different 3D universes, each inspired by one of the watch models. Elements of inspiration include shapes, curves and the gravure patterns.

Rendered in cycles (600 samples) on 2 PC. One with Nvidia GTX 690 and the other with GTX 660. Each frame took an average of 15 minutes to render with a maximum of 31 minutes ( when the train passes very close and generates lot of motion blur on the first scene (train station)).

Golden smoke particles are Particular in after effects, we also used Bartek Skorupa’s awesome script for importing blender cameras inside AE . Thanks man! This movie was made at RGBprod.

here is a gallery of some making-of images  :

train and locomotive based on great CC models by  KuhnIndustries and seavenois. Thanks guys

Nearly a year + 5min tutorial

Oh yes…. I thought I’d post something just before nov 17th… So nobody can blame me for not writing on this blog for over a year…
Still it’s very lame from me… but I have excuses …
And no there is absolutely no excuses for letting a blog die !!
Nevertheless we had the pleasure to have a second cool baby (A warm Hello to the handsome Louis that will maybe read me in 10 years from the future !) and thus did a bit less 3D work, more 2D , editing etc…

But now I’m back on track. And it starts with a new 5 minutes tutorial.

I love the 5 min tutorial format. It’s fast and effective… It is also more suited for intermediate/upper users, as it does not allow the time to explain all operations in detail, but draft out general ideas of a specific technique or trick. Fell free to ask for help in the comments.

And lastly, I am working on a nice 3d animation project at RGBprod studio… more to be unveiled at end of january.

Thanks

Blender production Challenges – Call for content (yes still a few months to go :)

Hello Blenderheads,
I’m Olivier, and I presented the Open-Stage blender Production Challenges at last year’s blender conf.
I would like to get your help for this year.
You can see my blogpost about last year here . And also the video here

Possible Improvements for this year:
Some things that will need to be improved :
– The internet connection at the conf venue (not my fault 🙂
– A way to distribute the challenge files faster.
– A better way to interact and discuss with online people (have someone in the room to check IRC and help participate)
– Have more people sending in the challenge files before the conference.

Call for challenge files
So, this post is all about the last point: I would like to get more files from you, blender users.
Usually these challenge files come out from a problem that you had (or still have) during a production or image creation. They have a broad range: Something that weirdly behaves not the way you want or expect (no bug wanted here, it could be just a rig that maybe doesnt bend correctly even with rotation locking, or maybe something that you are stuck with, like how to change the color of an instanced group randomly. Other examples: you try to render an image, but an object doesn’t render correctly.
I will not be able to show all files during the conference, and will have to do a selection of the most interesting ones. The ones that could start a debate or technique sharing. But possibly all will be shared somewhere online after the conf.

what to provide
The best format is a simple lightweight blender file, which focuses only on the problem. We do not want too many useless artefacts around. A bit like when you send a bugreport file, you squeeze it down to only the part that you are interestred in. For example if your challenge is about rigging, you do not need a complicated animated sculpted textured character.
Ideally you should provide a text file (inside blend file or outside as .txt ) with the explanation of the problem (and your solution :p). You can append images if needed. And try to rate its difficulty level ( we need hard ones, as well as easy ones) I might re-edit them a bit + beware that they will be redistributed, so be sure to provide only content that is not afraid to be copied around the world wild web.
If possible size should be reasonable.

Feel free to look at the files from last year and provide better ones 🙂

Thank you and looking forward to get your feedback and maybe files. You can send me a link to files oenvoyage AT gmail.com or by writing a comment here. I’m also on twitter @oenvoyage and sometimes on IRC

Blender conference + challenges files

In this post I will share the files I used for my presentation called blender challenges.
But first I have to apologize for posting a short blogpost, my wife is here and we are going to visit Amsterdam for 2 days, so not much time for writting 🙂

This was one of my best conference, if not simply the best! Got the chance to meet a lot of new people, especially some swiss guys this time too! 🙂 Hope we can do some gathering one day soon.

Apart from meeting people (which takes some time and even makes you miss some talks because chatting and sharing is so much fun) you also get the chance to see talks and presentation of techinques, researches or simply showcases of what people do with blender.

Blender Challenges
I had the chance and task to host the open-stage time slot, and so decided to share some files and problems encountered during some productions, but in a simplified way. It resulted in a series of 6-7 .blend files, with something wrong in them, and people would need to solve them.
The files were handed out at start of the talk, and folks had to gather in groups and try to solve them. The few first ones were rather easy, ranging from bad oriented normals, to overlaping faces. some others were a bit more tricky. The audience was very participative and it started some nice discussion and trick sharing, I loved it.
Instead of giving out the answers, I will give out the files for your pleasure and you can try to solve them.
Here is the link: http://dl.dropbox.com/u/6506660/challenges_2011.zip (1.1 mb)
I hope you can enjoy them as much as the audience did 🙂
Can you solve them ? Do you have some answers ?
Do not read the comments if you dont want to be spoiled 🙂
