Holographic / Projection Goblet of Fire
The idea is to recreate the Goblet of Fire from Harry Potter and in some way use holographics. Ideally, it would be cool to create holographic flames. I’ve looked at some YouTube videos to figure out some ideas for this project.
For the goblet, I am unsure as to what material I should use to recreate a golden goblet. 3D printing would be the go-to option, however, I am very open to other options as I would rather avoid having the 3D printed layers visible. I would like the make the final idea substantially large; that would be pretty cool to display.
1. Holographic fans: This uses a computer fan that creates a light image with the fast rotation of the LEDs on the wings. I think obtaining the fan might be very expensive. Additionally, the image is still in the 2D plane with this type of projection, so I wouldn’t be able to view the goblet from all sides and still see the flames. It would also be difficult to hide all the ugly pieces and only view the flames.
2. Image projection: There are various forms of image projection utilizing a smartphone I could use. I have shown 3 of them below. It seems impossible to have the hologram and hide the plastic used to project them.
4. Andotrope: This can make any flat image viewable omnidirectionally, from any angle, rather than straight on, without distorting the image. This takes the concept of persistence of vision, where an image is retained for a brief moment even after it has disappeared. So the Andotrope essentially tricks your brain into perceiving the full image is still there while viewing it from different angles.
The Andotrope is a cylindrical object that contains the image within. It has a viewing slot that allows you to see a slotted portion of the image when still. It functions by spinning at a high enough rotational speed so that the slot will pass by you to perceive the full image at any angle.
To make this “holographic,” the image must be a video of the object rotating. If the rotation of the object and the Andotrope are the same, it appears the object is stagnant so you can view the back of the object.
Geometric Light Deflection
For this, my idea is to create a geometric piece made of a reflective material. Each section of the piece would be angled so some of the light is reflected away, so each section makes up the shadows and highlights of the piece to make depth perceptions. Below is a concept sketch of a wolf with the idea. Currently, I am thinking of utilizing aluminum cans as a material. I want to brainstorm other reflective materials as well, and the project could consist of many materials rather than one.
Questions
Proposal 1:
– Which method would be most feasible, and I could still achieve aesthetic appeal?
– What other materials can I use to make the goblet? Or other methods other than 3D printing?
– Are there other holographic methods I haven’t presented here, some that have more ease to incorporate into a large goblet?
Proposal 2:
– What type of lighting can I use to shine onto the piece? I’m hoping to get the shadows and highlights to be pretty defined and intense, so I wonder if certain lighting materials will optimize that.
