Week 8 3D blog!

I was sadly sick during the lesson where went through how to scan your face and to actually do it so i was thinking of writing about my general opinion about 3D scanning in general as i got some knowledge about it thanks to a course I went last semester.

So there will be two different types of scanning that I will be talking about in this blog post. The first way is scanning with the help of photos and the second with the help of laser.

Scanning with the help of photos

The positive things with scanning with photos are that you could easily scan things while on the move. All you need is to have a camera with you all time if this is a very good digital camera or if it is your cell-phone you will be able to take pictures to be able to reconstruct the object in a 3D scanning program. This in my opinion the best thing about the 3D photo scanning technique. I was in Germany this summer and took picture in 360 (or as well as I could) so now I could go into my picture library whenever I am in need of sculpting that I could easily reconstruct into a 3D object and then model or bake with it, you could also just use it for the texture witch can help a lot when modeling low poly models.

The things that are negative with photo scanning is the resolution and that amount of photos that are need, as well as that sometimes it is very hard to cover big objects and areas. The resolution problem is that it doesn’t feel the depth of really detailed places if you do not take a close up witch might give you trouble with setting up the photos before creating the 3D object from the pictures. With the photos if you want a rather well resolution you will have to take a lot of pictures to get that kind of resolution. Covering a vast or big area is not going to work with photos the first problem you are going to come up against is the large amount of photos that you will be able to have and the time it will take you to go around and take pictures of everything and when setting up the photos in the 3D construction program is going to be long and painful firstly because of the amount of pictures and that you might have to manually lay out where they are supposed to be and this will take time.

Scanning with lasers

The positive things with scanning with laser are that you don’t really have to do much while using it. All you need to do is to set up the machine and then let it do its work. You can also get insanely good resolution with it because it sends out lasers to calculate the depth. So you can cover great space without you doing a lot of work yourself.

The negative things is that it cost a freakily high amount of money to get your hands on a laser scanner that you can use for scanning objects for 3D objects. It is also not that easy to scanning things without planning ahead because the machine that you will be using for the scanning is rather big and clunky so you can’t really take it with you all the time.

So this is my input of 3D scanning and I am not sure if this counts as a blog report but I don’t really mind!
