Could I have the code for the 3D pinhole camera?

The closer you are to the image you are trying to capture the farther away it looks. Its like looking in the wrong end of a telescope.

What if you wanted a clear,big and bright picture?

You can just take an image with minimum focal length and aperture and then later magnify it using software.

Why dose it get smaller when you go closere

Whenever the light comes through the hole in the middle, if the wall is closer, then it will hit the wall without traveling as far from the center. Thus, the image will stay in the middle of the wall, and be smaller as well.

Why is the capture picture thing sometimes a bunch of shiny dots and other times the actual shape?

It has to do with the aperture that controls how much light comes through and if too much comes through, it appears fuzzy instead of focused

Simulation

Below is a simulation of a pinhole camera. Try capturing images using different focal distances and then answer the questions underneath.

Questions

Increasing the focal distance makes the field of view

. This means that objects in the image appear

Increasing the focal length also causes images to appear

. This is because the rays of light are

spread out by the time they hit the image plane.

  The picture gets smaller because the light is less spread out over time.

Does anyone know if software that uses virtual cameras is available to regular people? Or do you have to work at or have access to a production studio or something similar?
