Hi, all !
I would like to show you another source of geometry for POV-Ray:
https://mathview.yesbird.online

I was enchanted by math surfaces from my school years, always like to
play with different math packages, including Mathlab, Mathematica and
now Wolfram Alpha.

Inspired by following sources:
https://virtualmathmuseum.org/
https://3d-xplormath.org/
https://github.com/parisolab/mathmod

I decided to write an online tool for exploring surfaces with simple and
convenient GUI, rich visual representation and export to most popular
modern formats (POV mesh2 also supported). For those who have an XR 
headset, I made available XR mode.

Now all main functionality is completed and I am starting to fill the
collection with the most interesting and attractive surfaces.

How to use:
-  Combine 6 materials and 18 textures for desired visual effect
-  Click twice on the color map icon to change projection
-  Edit surface parameters
-  Edit functions of surfaces, that has a 'pen' mark
-  Shift surface parameters in 'Settings' to see changes in real time
-  Take screenshots by clicking 'Camera' icon
-  Download geometry in 'OBJ' or 'POV' format
-  Enter XR mode by clicking 'Box' icon

Also there is a short description available by clicking (?) icon.

For POV-Ray users:
Download scene template with complete set of textures from here:
https://mathview.yesbird.online/data/templates/scene.zip

In MathView: select desired surface, download data in POV format,
save 'surface.ini' file in directory where 'scene.pov' is located.

In POV-Ray: render scene.pov with desired settings, try different image
maps, located in 'textures' directory.

I will be glad to get any kind of feedback from you, including
suggestions about surfaces to add.
