any flowers are easy. A bouquet in a vase. AI again
AI is good at this. Although you can't expect it to be very detailed, AI always simplifies and often makes things smaller and worse. You need to make several attempts and understand what he offers. Agree on the best option. For example, these are the flowers in the photo and this is the result after creating the model
another bouquet
still
It can be seen that AI has simplified all the photos very much. But in the end, you can get a variety of bouquet options. I took the finished model of the vase, added 0.2 and Ni 1.5 (optical refraction coefficient of light in glass) to the MTL file. I made water out of a cylinder. First, I assigned it a width and depth like a vase, then I leveled everything and after that I reduced all the dimensions of the cylinder by 1 cm. The water rose evenly inside the vase. Powerful small blue spheres of 10% each should be placed inside the water. they will provide the necessary light spots from the water next to the vase. To create models from photos, I used TRELLIS, improved the rendering quality using REMINI.

Re: any flowers are easy. A bouquet in a vase. AI again
I'll continue. AI works more efficiently if the subject in the photo is simpler. So I took a separate photo of a rose on a branch, one bud. When generating, a slightly different option is obtained each time, this is a feature of AI. You can get several different color models from one photo. With these different models, you get a natural, repetitionless, large bouquet. The lack of AI turns into a big plus. Now if you take a picture of this bouquet and try to make a model out of it, you'll get a terrible broom. Therefore, the method of individual flowers is ideal for a bouquet. You can make your own magnificent bouquet, like a professional florist, with the addition of herbs. Everything needs to be modeled through TRELLIS individually and assembled into a composition.
one more question for Keet. I noticed that the buds on the 3D model of the AI rose turned out to have a different transparency. The stem and leaves are opaque, and the flower is a little transparent! There is nothing about this in the MTL file! Is it even legal? How can that be? The texture is uniform, not divided into parts. Unbelievable. The transparency of the bud is very good, the flower turns out with a glow from the inside, a little like a real rose flower.

That is easy to explain. Transparency in an image is created by adding an alpha channel and then define a specific color as transparent. Exactly the same as how you create a transparent background. I think you can even define mutiple colors as semi-transparent, but I'm not sure. The rose petels that are semi-transparent have that transparent color mixed in.
