An Analogy on The Subjectivity of the Objective

-
I was 3D modeling in a cafe and I just happened to use Adobe Substance Painter in which the brush size does not depend on how close or further away you are from the object but instead has an unchanged ratio with the object size — I am assuming — essentially its point of reference is the object and not the user (myself), in comparison to Blender's brushes which have a fixed screen to brush ratio (which u scale up and down as needed) and so if you're further away from the object the impact of the brush is bigger, but if you're closer, it's less. Whereas for Substance Painter, whether you are closer or further away from the object will not affect any more or less vertices. Which made me think, in the realm of objectivity and subjectivity, which software follows an objective system?  Blender's screen-constant brush, which maintains a fixed screen-to-brush ratio regardless of distance from the object, may initially appear objective. The brush seems unaffected by the view

The Orthographic & Perspective/Objective Realism & Subjective Idealism.

Reality, as we perceive it, is a tapestry woven with the threads of our own subjectivity.   A year ago, while 3D modeling, I stumbled upon a question that shook the foundation of my understanding of reality: how can our subjective, perceptually dependent reality — which we view through perspective viewports — exist independently of an objective one, the orthographic viewport? This question, left unanswered, sparked an existential crisis that lasted over a year. The aforementioned has led to this revelation (the article you're about to read). The orthographic  viewport : From the 3D perspective, the orthographic viewport projects a 2D capture of the object in which all parallel lines remain parallel. The orthographic is independent of perception; the image does not depend on the distance between the viewer and the object, nor does it depend on the focal length.  From my perspective, which isn't very different, the orthographic viewport is one in which objects exist in their orig
