3D

Here is a 3D image you can move, using Scratch. Click here.  With your red and blue-green glasses, you can see 3D. Click the green flag and you can drag the circles left or right. If the blue-green circle is to the right of the other circle, the circle will pop out, when you wear the red and blue-green (cyan) 3D glasses.

You can drag one of the circles left or right but not up or down. The very simple code just adjusts the vertical position of the circles to be identical so that the two images stay in the same horizon. That way your eye can merge the two images.   

Here’s more code program in Scratch. Click here. This creates a cube that you can turn.  The code draws two cubes, really two views of the same cube, but in two different colors that your red cyan glasses can filter out.  The code also allows you to alter the perspective, and that is a bit complex.  In this simple version, we did not add trigonometry. 

 

 

 

Below are some sample images that you can view in 3D with your red and cyan glasses. 

Below are several stereo images, using two images, one for each eye’s perspective. For these you use the clear lens glasses that come in your box.

The first image (real pyrite) we made ourselves by taking two photos with our phone. The first photo took from about where our left eye is, then we moved the phone over three inches to the right, to about where our right eye is and took another photo. Then we placed each side to side. The result is a 3D stereogram.  We used this method for several images in your subscription box.   

You can view these with the glasses attached to your phone. Click or touch the image to adjust size and position.
