Removal....... sounds like a medical procedure.......applesause.
The octree method for hidden surface removal involves dividing the 3D space into smaller and smaller octants. Each octant is further divided until a certain criteria is met (e.g., maximum depth or minimum size). This hierarchical structure helps identify and remove hidden surfaces by checking which octants are completely hidden by others. The octree method is efficient for accelerating rendering in complex 3D scenes.
In 3D computer graphics, hidden surface determination (also known as hidden surface removal (HSR), occlusion culling (OC) or visible surface determination (VSD)) is the process used to determine which surfaces and parts of surfaces are not visible from a certain viewpoint. A hidden surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics. The process of hidden surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. The analogue for line rendering is hidden line removal. Hidden surface determination is necessary to render an image correctly, so that one cannot look through walls in virtual reality.
Since you can't see the hidden surface, from your point of view, then the graphics system should not (normally) display the hidden surface except (optionally) to display dashed lines for hidden edges and dashed dimension lines to hidden edges.

A hidden surface refers to a surface that is obscured from view by other objects in a scene, while an invisible surface is one that is intentionally made invisible or transparent, such as a glass pane. Hidden surfaces can be revealed by changing the camera angle, whereas invisible surfaces are typically always transparent.
onych/o = nail crypt/o = hidden (ingrown) ectomy = removal so my guess would be onychocryptectomy

They are mostly hidden underwater because nothing has yet made them erupt and come to the surface.
There is a hidden ocean on Europa as found out by NASA, manifested as churning seas beneath its icy surface.
