Only a few main features are implemented so far, but more are coming. Check it out at ThetaPad.art!
Note: This project is still under construction. I'm in the process of adding features, and there are still few minor bugs to iron out.
ThetaPad is a tool for visual artists. This free web app allows users to upload reference images and make comparative measurements directly on the image. For example, it in drawing/painting people, sometimes you want to know things like 'how many eyes wide is the mouth?' or 'what is the angle of the right leg relative to the left?' and ThetaPad's main purpose is to allow artists to get the answers to these question as quickly and easily as possible.
ThetaPad was primarily made to help eliminate some barriers to entry for aspiring visual artists. Professional visual artists of all kinds often use techniques such as griding, filtering, and measuring their reference photos, and they usually use software like Photoshop to do that. Photoshop is expensive, and it's not really even meant for those uses, adding not only a monetary barrier, but a skill barrier as well. This means many young artists, especially those living in poor and underprivileged communities, can't compete with the professionals. ThetaPad is my attempt to provide some of the tools used by professionals all in one website.
Shout out to my close friend and incredible artist, Nik (@blue.niklane) for inspiring the idea for this project
