jet set radio random vmu blast from the past mystery
How is this for random.

I need some background music so I turned to the internet streaming sensation
Radio Sega

On there I saw a link to The Dreamcast Junkyard
That has a rather surprising number of stories just from the last month, let alone year. After reading rather too many articles, I decided to look around and see if my Space Invaders VMU style was mentioned anywhere.
Nice, 7/10, not bad at all!

During my search I had come across a page about a limited edition Jet Set Radio graffiti set on VMU, could it be?

Remember when I was slightly confused at being asked to update some 15+ year old code to support 64 bit? It seems that that event used my code

VMU squad

and then, I found the Complete History of Seaman which was a really nice video and showed me loads of stuff I did not know about this under rated Dreamcast game.

blender fail companion cube
Yet another distracted Blendering I did recently.

This time I had a specific goal. To create the minimum of geometry and use Modifiers to do the heavy lifting. It did not turn out quite as I wanted, but there were some good bits so...

Looking at the Portal Weighted Companion Cube that I got as part of Funko Pop! Chell, it seems highly symmetrical, apart from the heart.

I started with a plane that I moved to the right and above the center point. Then cut it in half diagonally with the Knife tool and extruded a couple of subdivided edges.

After extruding into 3D two areas I used the Knife Project to slice two circles.
This did nothing other than create edges which I could then use to remove faces.

This 3D "slice" should be able to be rotated 45 degrees 16 times and we get the cube face! Not quite, needs to be mirrored and then repeated at 90 degrees.

I did try using an Array Modifier with a Simple Deform - Bend - 360 but it just bent everything, not just the layout. So I switched to using an Particle Emitter.

This seemed to work and just need the center reset, so instead of appearing at the extremities of the base plane, would create a single "face". I tried a lot here and I am not sure why it did not work. In the end I settled for Scaling the base emitter plane. First I tried a scale of 0, but that messed everything up, so I just scaled manually until I could not go any further.
Even though there were technically gaps between the "slices" you could not see them, even when zoomed in.

Then I extruded the edges in the base "slice" to get rid of the corner square holes.

Here I tried to use another Particle Emitter, but Particle Emitters do not like being Particle Emitters and everything I tried made things very messy, just emitting from cube.
Then I remembered hearing about Dupliverts. This took a lot of trial and error but eventually I Converted the Particle Emitter into a Mesh and Parented it to a Cube with Dupliverts.
The key was to clear all the Rotation, Scale and Transforms from the newly created Mesh.

Which made this rather cool basic Companion Cube.

It was a simple matter to add a 2D Mesh with a Mirror modifier and use the Proportional edit to create a heart. This was then Dupliverted with another Cube and joined to the Companion Cube mesh.

I could not help but add a plane as the floor, set it as a passive physics element and then duplicate a load of Companion Cubes as active physics.

This looked really cool in the Material view when previewed but the resulting animation(that took over 24 hours to create at 1920x1080) looked pretty rubbish because of the corners and edges over lapping.

I might revisit this in future. The initial Knife Project did not create enough geometry to get nice curves and I now see that the corners do not have a vertical cut anyway. Would have been nice to line up everything, for this I just need to have been more careful earlier on. Could have skipped Particle Emitter and just stuck with Dupliverts.

The end goal would have included making the edges nice and smooth. Now I can also see my Portal 2 Cube has orange lines appearing like cross hairs on each face.

distracted star growth blendering
Here is another distracted Blendering I did recently.

It is insanely simple to set up.

Extrude a single plane from the default cube and scale to a point. Then add an Array Modifier with Simple deform - Bend - 360.

Then animate the Array - Count. I then edited the animation curve to make the progression start slow and get faster.

Finally the Principled BSDF material with a healthy dose of Sub Surface gives the object a realistic depth in the lighting.

xmas 2017 better late than never
Oops, forgot to post this render from Xmas

3D render of an Christmas tree in the snow with presents and snow flakes

The tree was created using the built-in Sapling Tree Gen. This creates a curve that can be Solidified then tinsel added by my usual method.

The presents were created and animated as with last years, just with a bit more care. The presents fell from a much lower height and I used the default physics settings. The bows were quite time consuming, but were basically extruded curves. The texture was something that did not quite work out. I wanted to use procedural textures and this is the Checker texture stretched. Looks fine on the sides by totally fails on the tops and bottoms. I could have fixed this with more time.

The snow flakes were a simple plane extruded a couple of times with a mirror modifier and then an Array Modifier with Simple deform - Bend - 360(which is my new best friend). Then duplicated into a large grid and Randomly transformed.

I desperately wanted to light is with an HDR image but the results were not very good, so I just rendered with a transparent background and used Gimp to added the gradient.

One last cool bit was using the Principled BSDF with Sub Surface to give the ice and snow a realistic sheen. More on that in another post soon.

Not quite as late as last year's :)

a 2017 yearly review in january what
2018 already?
Tis the season to do a yearly summary.

First some stats. Since adding an rss xml feed back in 2007 I had forgotten I had a happy little script updating an xml file with every post. But this f-log has been running since 2002
