Goodies, tips, and tricks Put Babel boxes on your user page so others know what languages you can speak and indicate your graphic abilities. You can find the files you have uploaded in your Uploads. Please sign your name on Talk pages by typing ~~~~. To link to an image page without embedding the image, type: [[:File:Foo.jpg]], which produces: File:Foo.jpg. You may enable gadgets (custom features) for your account. There are several tools to upload files. Have you edited Wikipedia before? This guide might be useful. Made a mistake? Do you want to have a file renamed or moved? Use the move link and wait for an authorized user to rename it. Do you want to have your recently uploaded picture removed?

Images

Hi. Thx for grat images and videos. Can you describe how you do them ? What software ? TIA --Adam majewski (talk) 13:48, 20 January 2021 (UTC)

My favorite tools are POV-Ray and the GAP-System. POV-Ray is a great open source ray tracer for creating photorealistic 3D images. Check out the site at povray.org. The GAP-System is a great open source package for group theory computations. Check out the site www.gap-system.org. --PSL27 (talk) 01:40, 21 January 2021 (UTC)

Categories

Hi, please be more specific with the categories for your images.

• File:Nauru-graph-on-torus-2.png and File:Pappus-graph-on-torus.png belong in Nauru graph and Pappus graph.
• Many of your images belong in the respective subcategories of Spherical disdyakis polyhedra.
• File:Orbit-of-Wythoff-tile.png belongs in Truncated cuboctahedron.

Rarely any image belongs directly in broad categories like Group theory or Polyhedra. Greetings, Watchduck (quack) 21:49, 23 March 2021 (UTC)

Very good suggestion. I see that you have been quietly adding appropriate categories to some of my files: thanks! Thanks also for your excellent ray traced images. PSL27 (talk) 00:51, 24 March 2021 (UTC)
