Brain tranforme real world image to 3d
- Binocular vision (2 eyes) is what give depth perception
- This mecanism is helped if the targeted object (or you) are in movement over a more stable far away background
- Persons with one eye left will compensate by limited head mouvement
- The bigger is the distance between observed object and backgroud the more you will feel the depth
- In protrait 2d photography , photographes will do shallow depth of field by in order to blurr the background producing a more 3d preception.
- I still have myy pany ptax 100 and project on a big picture (3.2m wide , head position at 4 m is in the exact center of the screen). This gives me already a 3d like imersive experience of moving objects and even if I focus on one small part in the center of th image (central vision of retina) I can still see undeltailed background (peripheral vision) that helps my mind make it look like 3d.
- I dont know much about 3d on a big screen yet, but I feel that below a cetain size (rather angle of view) , you won’t feel what real imersion is , unless your room is black and light controlled so that all that is hanging on your wall won’t intrude and distranc your imersion (peripheral vision).
- I think that these « installation » considerations are as important as the choice of a good projector. and should figure somwhere to help peaple understand this beacause its a big factor of successfulll experience.
