Geometric abstraction was advanced by Russian abstract painters from 1910-20 or so. Look for constructivism and supremism. They are much closer to what you are exploring than cubism. That early abstraction was looked down on after the Russian revolution because it didn't adhere to the new cultural programs. It gave way to social realism fairly quickly in Russia. Germans adopted it and Bauhaus was directly influenced by it. Cubism is actually an evolution of multiple perspective depiction. It wasn't so much about cubes and angles as showing top, down, left, etc all in the same image instead of just one perspective. Some think of it as a style that Picasso invented, but there were many influences that evolved over time and it wasn't just a style but a whole process. Many other painters of the time used a multi-perspective approach.
