Problem with realistic representation of light reflection from mirror in generated graphics

[hallow lark]

#1070006915414900886 Hi,

I am working on visualizing a realistic scene with light physics, but I have encountered a problem with generating precise reflection of light from mirror. The scene should show:

1. A narrow beam of light entering through a small hole in the wall.

2. A person holding the mirror at a certain angle (e.g. 35 degrees) in such a way that the light is reflected onto the adjacent wall.

3. The reflected beam hitting the other wall, creating a clear, sharp point of light.

The problem is that the generated images do not correctly represent the trajectory of light, angle of incidence and reflection according to the physical principle (angle of incidence = angle of reflection).

I am looking for help with:

Developing an accurate prompt that will force realistic representation of reflection.

Alternatively, use graphic tools (e.g. Blender, Photoshop) that will allow you to manually create this scene.

If anyone has experience with this type of project, please give me some tips on how to properly present this effect in a realistic way.

Thanks for your help!

Interesting, what is your test prompt for this?

[hallow lark]

Prompt:
"A realistic scene in a dark room. A single small hole near the bottom of one wall allows a narrow beam of sunlight to enter. A person is holding a small mirror at exactly a 35-degree angle to the beam of light. The mirror reflects the beam of light onto the right wall, creating a sharp, clear spot of light. The room is empty except for the person and the mirror. The perspective is set to show the beam entering, bouncing off the mirror, and hitting the wall, emphasizing the alignment and angles of the light path."

remove the word realistic from the prompt, it implies realism as an art style.
dall-e and also sora, as stated by OpenAI are not accurate with physics, this specific degree of optical physics won't be accurate

What kind of beam is there? spotlight, column, laser-like? Reflection, does it have diffusion, dispersion, scattering, filtering, optical aberrations?

I wrote without realistic, I tried several times, I still can't reflect a beam of light coming out of the wall from the mirror, I can create a village e.g. laser etc., but I can't reflect a beam of light from the mirror onto the wall.

that's just one aspect, look at my extra notes

[hallow lark]

ok, as soon as I find time I will practice but I will be grateful if someone manages to do it before me because I have been thinking about it since yesterday

Hmm, there is still a problem. In a dark room in the desert there is an opening through which the Sun enters in a kind of beam. A man opposite the beam reflects it with a mirror onto the wall. The reflection of a sunbeam from the mirror onto another wall is at an angle of 45°, giving the effect of slight optical dispersion onto the adjacent wall and showing the optical phenomenon of light reflection.

that was gonna be also my follow up, what kind of light source do you want?

or is there even a light source at all

light in the image doesn't necessarly need to have a light source defined, but it can have a direction still

[hallow lark]

still a problem

Of course, light is a physics thing, it's a problem, we just try to tackle it. I'm also trying different ideas on my side. but nothing concrete.

Optical Aberrations and phononema are great, but reflections are still a problem. For example this one was about dynamic lighting as the technical optical focus

and this one, even though it looks cartoon 3D, the purpose of mine was to direct the lightspot with difussions and aberrations

I've yet to get find out how to control reflections I had this concept where some tiles are reflecting light, and some are not.

I did an experiment, maybe chat will learn how to reflect light with a mirror in the right direction

So I made a hole in a Prigels can and created a tube like a flashlight, from physics and practice it follows that moving away light causes the circle to grow and the light intensity to disperse

The next experiment is a marker tube attached to a telephone with tape, creating light, in a box in which there is also a mirror. This study shows exactly how interesting the phenomenon of optics is.

It can be observed that:

The light generated from the tube, which illuminates the mirror, depending on the position of the mirror and the angle of the mirror, redirects the light.

When the mirror is near the illuminated side, it is slightly larger than the surface of the mirror and when we move away, the light increases, as in the case of the Prigels experiment

What do you think, can I teach the chat this technique? Maybe I should put together what I want to convey better
