Rough and ready image rendered in real-time in Marmoset Toolbag 2, still alot of work to be done on this. Part of a larger personal project, will share more when I can.
2015 in review
•December 30, 2015 • 1 CommentThe WordPress.com stats helper monkeys prepared a 2015 annual report for this blog. Thanks to everyone who visited, a small increase on last year’s numbers!
Here’s an excerpt:
The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 34,000 times in 2015. If it were a concert at Sydney Opera House, it would take about 13 sold-out performances for that many people to see it.
Hard rockin’…
•December 8, 2015 • 2 CommentsAfter a storm battered, yet enjoyable weekend in Donegal with family and friends, I took some photos near the shore of Lough Foyle for 3D scanning. I used Agisoft Photoscan to assemble the high poly rocks, then Meshlab and 3DSMax to create a low poly version. I then extracted normal and AO maps and conformed the textures for use with PBR in Marmoset Toolbag 2 (still work in progress). There has been considerable interest on how this was created so I will post a detailed breakdown over Christmas. In the meantime there are some high-res images below.

Gravel Pit…
•November 24, 2015 • Leave a CommentRecently my Dad had some gravel delivered to his house and I happened to have my camera with me and took some shots for 3D scanning. Here is the low poly result as rendered in Marmoset Toolbag 2 with extracted Normal, Height and Ambient Occlusion from the high res model and hand painted Albedo and Roughness maps. Unfortuantely I didn’t take enough source images for complete photogrammetry, so there was a quite a bit of reconstruction involved.
Raptorous…
•September 29, 2015 • 1 CommentI’ve been ticking away at some modelling and printing these past few weeks, here’s a Velociraptor I made for a thing. The top image is outta V-Ray, the next three are real-time from Toolbag 2 and the last is a photo of the 3D print in the flesh. One arm didn’t make it, I’ve been trying different methods to pull out a better version, will update if successful!
A Hard Place…
•September 9, 2015 • 5 CommentsIt’s been quiet on here for a while, life has interfered! I’ve still been busy, I took a week’s holiday back in August and spent some time along the North coast of Ireland, photographing rocks to be used in real-time experiments. I used Agisoft Photoscan and Autodesk Memento to turn the series of photos into high res 3D models, these were then reduced in poly count and their textures conformed for use with PBR. I also worked out a way to sharpen edges where details were lost in the mesh construction.
Rendered in V-Ray and also in real-time in Marmoset Toolbag 2 and 3DO.
Kitbashed…
•July 8, 2015 • Leave a CommentLately I’ve been looking at SketchFab and Marmoset Viewer as a means of displaying models in real-time. Both have their strengths, Marmoset allows a really nice split screen view of the various textures that comprise the material, while SketchFab currently allows more post-processing than Marmoset, which is also cool, and I love that the viewers work on mobile too.
I’ve also been doing some more 3D printing, further testing what I can get away with on the Ultimaker in terms of structure and resolution. Here, I kitbashed a quadrupedal mech from a robotic leg I was working on before, it turned out OK considering how brutal the booleans were (thanks Zbrush!).
It required a lot of supports, generated in Meshmixer and these were tricky to remove safely due to the finer mesh details, in fact I wasn’t sure it had printed at all given the mess of exterior supports.
Here’s the print:
Obligatory realistic rock…
•June 23, 2015 • 3 CommentsA brief respite from 3D printing, here is a rock model that has been reproduced from photos of a boulder on a beach in the West of Ireland, rendered in real-time using the SketchFab viewer. The benefit of SketchFab is that the model itself can be presented and interacted with, rather than just embedding a static image from a given angle. I’m thinking of doing a Twitch stream or YouTube video to show how it was made, another task for the to-do list!
If you click on the image below it should open in a window where you can rotate the camera and view the rock from all sides
Four more years…
•June 16, 2015 • Leave a CommentWordPress tells me it’s my 4 year blogging anniversary! I can’t let that go by without marking it with some content, as has been the trend of late, some more 3D prints. This first one you may recognise from this post, although the fine wires of his beard hair would have proved impossible to print so I opted for a chunkier, swirled hair effect that would print more reliably. The print is quite small, about 7cm tall, so I was impressed at how the printer handled the fine detail and as usual I’d like to come back and refine the model to print again larger and at higher resolution. I’m reminded of Victorian horror when I look at him, I think a top hat and Inverness coat could suit him well, I’ve called him “Dr. Jekyll” for obvious reasons.
I was in work last Saturday and the printer was free so I checked the archives to see if I had any personal work I could stick on. I found the Mudbox file of this guy and it looked like it could be pretty much ready to go as it was. It printed very nicely, it is more or less wedge shaped with a thick base which tapered upwards towards the nose, so it didn’t require any support structure or clean up afterwards. I also printed a separate mask but it didn’t fit well and was very thin, in hindsight it would have been better to combine the models and print as one. Anyway, that’s that and here’s to another 4 years!
