Studio Rat bike

Here's a render of the bike I've been working on for a really long time. It's a Blender project aimed at expanding my skills in the program.
I generated this model using Agisoft Photoscan from photographs taken by a colleague in North Carolina. It's a highly modified Yamaha XV 750 Virago. 

I'd noticed the cheeky USD forks but really wanted to know where they came from. Well it appears that they are from a Suzuki GSXR. I don't know much more than that except to say that it must have taken some serious work to replace the entire front end. I wonder how she rides?

Sarah & Duck

My daughter is 2 and a half and loves Sarah & Duck... which is a bonus because so do it!! It's fantastic. Sarah is this super cool emo-chick in a hoodie and the duck is.. well, just a duck. I'm working on my Blender skills right now and decided to use this as a test bed for building a very simple character.
This is a fairly rough first draft. Eventually I'll recreate the textures properly and pay some more attention to the materials. Perhaps at some point I will do a lighting study or create a scene for Sarah to have an adventure in... but for now, there's just this

Fork design

I was on pinterest the other day and became really inspired by all the amazing utensil design.
Here's my crack at a fancy fork..

Vray DOF recreation

This is a like for like recreation of a shot I found while trawling the internet. I can't find the reference for this so if anyone knows PLEASE let me know and I will credit it.
Post-production depth of field plugins have been round for a while and do a great job in production. That being said, when it comes to refractive and reflective surfaces and materials... well, a normal z-depth pass can't handle it.
Granted there are some obvious differences between the render and the photo but the test achieved what I set out to find out. (how rendered dof reacts for interacting reflective and refractive materials)
  

Leica camera Corona test

This is a test for the newly released Corona renderer. At the time of rendering Corona was still in Alpha testing and I decided to see what it could do. In comparison to other iterative engines that I have trailed I found it extremely straightforward to use. The render times are long compared to a biased rendering system but I think the results are worth the wait.
This image also has some creative post production which was not part of the initial render.



The second shot is a straight render using Corona Alpha.

Jet Fighter circa 1850

I was inspired recently by a piece in a magazine. It showed an element that was really out of place but had been made to blend in with the surroundings. This Harrier jet in a pre-ww1 street scene is my effort.
Modelled in 3ds Max, rendered with very and composited in Photoshop.

slitscan prop rendered result

This is an example of the seamless texture generated by the slitscan technique.
Because the captured texture is so close to the final requirement, the time needed to produce the final piece is minimal.

Slitscan textures & map generation

I purchased a cheap motorised turntable from China about a month ago.
This was intended to be used for a photogrammetry project but instead became
really useful for a different application.

Slitscan photography or temporal photography is typically used for photo-finish images in eg. the 100m sprint.
There are some examples where it has been used in a different way

This script by Martin Dixon processes a video file and extracts a strip of pixels. These are then stacked together
to form a single image.


I sat a bottle (empty) of beer on the turntable and switched it on. I then set up my
Nikon 3200D to shoot portrait hd video.

The processed file looks like this:



Taken into Photoshop and processed. I needed specular, diffuse, mix and normal maps
to create the final rendered version in 3ds max.



I created a simple studio style lighting setup and rendered using Vray. The model that I mapped it to is a generic bottle. At some point I will recreate an accurate Moretti bottle. This should complete the look.


Observations at this stage: The lighting while recording the footage needs to be more even as some of the colours are not accurate.

The normal map for the glass is a bit on the heavy side. It seems to be suggesting a condensation look.

The camera wasn't aligned correctly when I recorded the footage, and as a result the textures are wonky..

Other than that, I feel this is a pretty successful first attempt at seamless, (semi) automatically generated texturing for cylindrical based objects :)

3d scanner progress

I've recently done some experimenting with 3d scanning in its various forms.
Started with an Xbox kinect. I was blown away with the result for the cost of the sensor but not really usable in production:

We bought a NextEngine desktop laser scanner a while ago. It's dead slow but the quality is great.

After that came the Artec Eva. Mental fast but no textures on the version we bought. Test scan went ok.



VW mk1 Golf GTI

So, long story short. I've always wanted one of these cars. I started to model one while I was at University in 2002. Five remakes later and I finally made some images that I was semi-happy with.

I'd like to do another remodel as I now have a real one in the garage. We have an Artec 3d scanner at work so I suppose I could give scanning a go. That being said, I'd definitely just use the scanned result as a base to retopologise on top of.

gallery... again

I started a blog a year ago to document my work and some cool stuff that I'd happened upon the way. A few months later the site closed down and it was all gone... Downer!!

So now I'm back and starting a new blog. The aim of the blog is to mainly document my CG and photography work. I may post some influences in and amongst too..
