A man in a small room with mirrors
I want to tell you how to place an image of a person correctly if the room is very small. And there are mirrors that complicate everything.. there are only two types of such a person's disposition. 1. A person takes pictures of himself in the mirror, there is no one else in the room. 2. A person takes pictures of himself in a mirror or just the interior, but someone takes pictures of him from the outside (this will be the picture on the render). These two types of rendering differ from each other in principle. Mirrors are usually hung vertically in interiors. Therefore, there is one important rule. A person who sees himself in such a mirror always sees his eyes strictly at the horizon level. And more than that. All the lines in the room will converge directly into his eye (he will see it in the mirror). It can't be any other way. Only if these lines are not horizontal or the mirror is hanging crookedly)). this is if a person just looks at himself with his eyes. But if he has a camera or smartphone, then the horizon line will shift to the lens level (now these are the main "eyes", they fix the interior, and the person's eyes will be in another place in the picture, somewhere nearby))). I decided to place a girl with a camera in a small laundry room. I found a PNG image with a transparent background. The girl has no legs, but it's not scary when the mirrors are not up to the floor. These are all mirrors above the sink, for example. Usually, the reflection in the mirror starts from the waist, the legs are not even visible. I have two such mirrors. One is large above the ironing board, the other is small opposite above the sink. The girl should be reflected in both mirrors, this is not an easy task. Because it is difficult to place everything so that everything looks true and does not interfere with the review. so we need to determine the height of the girl. I decided that she would be 170 cm tall. And the most important thing in a person is, of course, his eyes. They are at the level of 170 minus 15cm =155 cm. But first, I made a mirror copy of the image in the converter. Then, in a photo editor, I turned this mirror image into a view from the back, drew hair directly on my face, drew a finger that holds the camera body from behind, and so on. It is not necessary to do everything with photorealism, the reflection will still be small, and the main image in front will be very high quality.
I made a 0.5cm thick and 140x140 cm box. I placed these two images in front and back, and made the other sides invisible (this method is patented by the respected Keet, try to apply it carefully and efficiently)). Yes, I forgot to say - you can't make mirror copies in SH3D, something is wrong there and the image on the render turns black. Only in the online converter. And the thickness should not be very thin, 5mm is fine, otherwise the images will jump over each other and stick together. I had it like that))) In order for the girl's eyes to be exactly at the level of 155 cm, I put a bright green box 155 cm high in front of her. And he moved the box with the girls so that the eyes were exactly in place at the top of the template. But the camera is below the eyes! 5 cm lower, i.e. I need to set up a SH3D camera with a height of 150 cm. Now you need to place the girl very close to the closet behind her back, but so that you can highlight the top of the box with a thin hemisphere, where the head is located. Small rooms are always small for an overview of the interior, you need to make room here. The SH3D camera should be slightly in front of the girl's face, at least 1 cm. if everything is positioned correctly, then the lens will be reflected in the mirror exactly at the intersection of all the lines of the room (if they are horizontal, you remember). And they are like that everywhere. I advise you to make the size of the box a little larger than the real size of the girl, otherwise it will be very small on the render. In the mirror, an enlarged image of a person will look as if he took a step forward. That's all. It's better than going back and sticking your back to the closet. The picture will be like this in the end.
I want to remind you that the best quality in SH3D is obtained at the fourth quality level with the Glossy setting. There is a minimum of noise and fine chrome details (wires, thin handles) are perfectly obtained.
With this arrangement, the girl's head will block the problematic black square, which will necessarily be in double reflections in the mirrors after the second cycle. Interestingly, there will be more of these cycles on simple mannequin-type models. 7 cycles, then blackness. Sometimes you can get more loops and a smaller black square in the mirror and in complex scenes. But you don't have to worry too much))
there is a second kind of picture. When the SH3D camera is located nearby, and at a different height. The girl with the eyes and her camera is at its correct height, and the SH3D camera is at a different height and nearby. Such an image cannot be obtained in reality. Or it will be Agent 007's invisible camera, the size of a mosquito. But nothing is impossible for us. So I assigned the camera a height of 165cm and moved it to the right. The result is a more interesting reflection in two mirrors, yes, there is a black square on the third cycle, but otherwise it looks good. This option allows you to move the box with the girl more freely, because she does not fall into the field of view of the SH3D camera.
