Hi. Dear tdanielson, in the topic about the dog mat, set an interesting task. In the process of answering, I had thoughts on how to simulate circles on the water in the pool. the fact is that from a certain angle to the water, it is very difficult to see objects underwater. The surface of the water in a calm form turns into a strong mirror. Therefore, it is difficult to see fish on a fishing trip, everything is sparkling and the sky is reflected. There are no fish in sight. I decided to follow this principle further. In the group of stucco decors, I found a round ceiling rosette with smooth spiral surfaces, without patterns and decors. Exported to OBJ, assigned the transparency coefficient d 0.3 in the MTL file, the optical refraction coefficient Ni 3. I took a flat mirror for the surface of the water, at the beginning I got an unnatural picture. Dogs on the mirror. Of course it doesn't look like water in any way. Although in the early morning you can see a similar picture on the lake (just not with dogs)))
I've added a normal fuss to this idyll. He added transparent jets of fountains, brought rabbit friends and, of course, a cat. And then, of course, the water should become different. We need waves. Circles on the water appear from outriggers. These are the centers of oscillation. The nozzle of the fountain, animals, objects trapped in the water. I placed transparent thin sockets on these outriggers, directly on the mirror, and added more sockets irregularly along the banks of puddles. Added it . It turned out to be complete chaos, of course, but it already looks like choppy water.
For more open water, the method of a large number of circles was no longer good. It was just terrible and the program couldn't cope with reflections and refractions. The computer is frozen. And then you need to temper your ardor and remember about the morning lake. Circles are only in the right places. I made outriggers for a dog, a Minion, a ball in the water, a ladder support. The rest is calm water-a mirror. Then you get a calmer picture and the computer works without freezes.
