Explain Octree method for hidden surface removal?
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.
What is hidden line surface?
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.
Why hidden surface should be removed in graphics system?
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.
What has the author Mark de Berg written?
Mark de Berg has written: 'Ray shooting, depth orders and hidden surface removal' -- subject(s): Geometry, Mathematics, Computer graphics, Data processing
What is the difference between a hidden surface and an invisible surface?
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.
What is the surface of venus hidden by?
Posined gas.
What is the medical term for removal of ingrown?
onych/o = nail crypt/o = hidden (ingrown) ectomy = removal so my guess would be onychocryptectomy
What is the removal of surface material by wind and water?
erosion
What is A-BUFFER method?

Explain why the surface of water in a container is not flat but curved?
Surface tension.
Where are most of earths volcanoes hidden?
They are mostly hidden underwater because nothing has yet made them erupt and come to the surface.
