Photogrammetry 2.0 – bits and pieces

Since last week, I have been trying to create a 3D model of my latest painted piece; it has been a fun nightmare.

My previous model was quite challenging as it required me to go take more than 400 photographs and required 3 different sources of light to get rid of most of the shadows, however, I only needed to use one side of it so everything worked at the end.

My new piece is quite different, in order to allow people to navigate it from inside, I have to create a 360 model of it, this sets a bigger challenge for proper lighting and placing on the space.

My first idea was to hang it so a could take photos from all the angles, that did not work because it is impossible to keep it still inside of the studio, apparently, a ghost breeze lives within the room.

Next, I did take lots of images placing the object in three different positions over a plinth, so far I was able to make good enough models from three chunks of the original piece, now I have to figure out how to stitch them.

My reflection:

I think that this “chunk” process might be the best way to go, although it is a bit annoying to put the pieces back together, this workflow might allow me to create bigger and complex pieces without worrying too much about RAM processing limits and might be a modular approach for model handling.
