OpenCV with external camera – check

June 9, 2010

I’ve managed to get the external camera working with Processing and OpenCV on my mac. I thought it would be more difficult as I tried it about a month or so ago and it didn’t work. Oh well, it works now so I don’t care. I hope it just carries on working right up to the end of the show.

This image shows that the ‘index’ needs to be changed to indicate which camera input to work with when there is more than one available:

So this is one thing ticked off my To Do list.

I’ve also now been booked onto a slot for using the laser machine next week. If all goes to plan I’ll have a nice panel to use for my plinth which should then match with my sculpture as the same pattern will be cut into it. That way there is some correlation between the two and will be easier to identify that they are part of the same installation.

I’m also slightly concerned about how heavy the sculpture will be. It is meant to be wall mounted but the brackets I am thinking of using may not hold it up. Not to mention screwing the front (pattern cut) panel to the back (blank) panel.

I’ve just been reading that if drilling, a fixed or lathe drill is best for metal. For aluminium a fast speed rate but slow feed rate is best. Which means that the drill bit should be spinning really fast but should be pushing down through the material relatively slowly (I think). Handy info on drilling can be found here: http://www.diyfaq.org.uk/powertools/drillfaq.htm

Ideally it would be good to do this at the 3D resource center but then I’d have to leave the parts there through the week and won’t be able to do anything in between the Wednesdays. Not really an option.

There’s a DIY type shop at the corner of my road. I think I’ll pop in there to ask them what kind of stuff they can do. They might even be able to cut all my plinth parts for me and then I can assemble those at home and hopefully (if my car is fixed in time) drive it to uni when needed.  When it comes to this stuff I haven’t really got much experience. I’ve only ever really put some flat-packed wardrobes up. They came out well and are still standing so it’s a good sign I say. Oh and theres the random wood works I did when in school – that was fun. But back then it didn’t matter so much if things didn’t line up all that straight.

I’m also going to have a rifle through some of last year’s show plinths at uni. There might be something that can be recycled.

I think I should sleep now, I have a feeling tomorrow is going to be another looong day.

DXF formats and floor plans

May 20, 2010

Boring title I know but it’s late and I can’t think of anything better. Anyway…

I feel a little restless when I’m at work where I suddenly remember something that needs to be done for the project or I think of an idea that could help solve a certain issue with the practical work but I’m unable to do anything till I get home in the evening, by which time I’m usually too knackered or think of something else that also needs to be done. It is the first time since starting the course that I’ve really felt the disadvantage to being part-time.

Progress with materials: I was originally going to get some aluminium laser cut but that was going to be quite expensive. Then a very kind professional sculptor (Sahand Hesamiyan) advised me on the possibilities of having it water-jet cut instead. So far this appears a better and possibly cheaper option and without the potential to leave burnt edges where the shapes have been cut out.

I’ve prepared the pattern file in Illustrator, converted it to DXF (which is a CAD file) and have sent it off to find out how long the machine will take to cut the pattern which is where the cost starts to mount up. As it’s quite intricate compared to the kind of things they usually cut (like mechanical parts) the cost will probably be quite high (relatively speaking). But I’m hoping that even then it comes in at a reasonable price, compared to the laser cutting option. Will give an update once I find out.

———–

The full-timers on the course have speedily got into the organisers mode and got the cogs turning in terms of getting the show sorted. Not one to sit back and do nothing, I’ve contributed some time in measuring our exhibition spaces and drawing up the floor plans. These were sent to the group, and are especially important to the on-liners who are unable to come down (some being abroad) and who will need to have an idea of what the physical space will look like.

Floor plan of dark space (will be kept in darkness with only selective lighted areas)

It really makes me think about all that is involved for solo as well as group shows and this process makes you think about things from a different perspective. I’m totally more in tune with the importance of exhibition spaces being suitable and in a way I now have more refined ideas of what would be perfect and what isn’t but would do anyway. And also how to make the most of what you have. Now, what I’m actually hinting at is the fact that the space our group has been allotted in the MA show isn’t really as big as it should be (simply because we’re having to accommodate the space rather than accommodate our work. But compare this to how much space the other larger groups have to share and, well, we’re not as bad off.

Plus, if I get the sculpture looking good for this then I may have a better chance of getting this and bigger work shown at a local gallery.

I’ve just found a great site and some great artwork. It encompasses a large idea I had of producing some of my own designs in some kind of 3d form, as well as the theories on which my research is based. It also relates back to the image in one of my earlier posts where I mentioned the ideas of Donald (H.S.M) Coxeter and showed how a hypercube could be evolved to a higher dimension of shape.

Grossman also mentions the subject areas that I am interested in exploring in my research and which will link to geometry.

Grossman says:

I’m an artist exploring the region between art and mathematics, and this is my gallery and storefront. My work is about life in three dimensions: working with symmetry and balance, getting from a zero point to infinity, and always finding beauty in geometry.

That’s to say, I like to think about shapes, and occasionally I think up a new one, and usually they come out very symmetrical.

I highly recommend visiting the site http://www.bathsheba.com/. Grossman explains that her motivations for creating the metal based sculptures are far from commercial and she simply prices her work in order to make it available to anyone and not just those with large amounts of money. She also explains her working process, conveys her working space through images and descriptions and allows visitors to her site use of her 3d-print images for furthering their own practice in creating similar work.

Grossman tells us of her efforts to find a suitable solution for creating her work and does so in a very open manner. The site is written and maintained in her own words and not through a third party. All these elements combine to give a very friendly perception of her personality and her work and just a strangely comforting good vibe about her intentions.

Regardless of all this, I think the work is remarkable. The 3d forms allow for different angles and views of the pieces, each time making them look a little different, and also for the effect of light and dimness to show the deeper cutouts and interlacing of sections. This adds to the look and feel of the sculptures and the complexity makes them look like inverted mazes that you’d want to shrink yourselves into in order to explore.

Hmm perhaps a maze is something I can work with? Will develop this idea later me thinks.
