VR-All-Art's database stores a wide variety of digitalized artworks that have been placed into virtual reality environments, where visitors from all over the world can access them and experience art as if they were seeing it in person, in a real-life setting. This virtualized art is similiar but not the same as what most sources refer to as "VR art".
Originally, VR art is a term for art created in and for virtual reality. Artists who create VR art usually do so using Tilt Brush or similar applications for VR devices. Recently, however, the term VR art has expanded to include artworks created in more traditional ways -paintings, drawings, or other- that have been digitalized and placed into VR. A more accurate term for this type of art would be "art in VR", as it differs significantly from pieces that exist only within virtual environments.
Terminology aside, you can view all of the artworks on the platform in virtual exhibitions wherever you are, at any time. Enjoy!
