DEPTH BIAS Meaning and
Definition
-
Depth bias refers to a phenomenon in computer graphics and game development where objects that are closer to the camera are given priority or bias over objects that are farther away when rendering the scene. It is primarily used to prevent graphical glitches and artifacts that may occur due to the limited precision of depth values in the depth buffer.
In computer graphics, a depth buffer or z-buffer is a data structure that stores the depth value (usually the z-coordinate) of each pixel in the scene. This information is crucial for rendering objects correctly in relation to their position in the scene. However, due to limited precision, depth values can sometimes cause visual artifacts such as flickering or overlapping of objects, especially when they are very close to each other.
To mitigate these issues, depth bias is introduced to shift the depth values of closer objects slightly closer to the camera's perspective or away from the far clipping plane. By biasing the depth values, closer objects are rendered slightly in front of farther objects, reducing the likelihood of graphical glitches.
Depth bias can be manipulated by adjusting factors such as depth bias constant or slope-scaled depth bias, which determine the extent of the depth value shift. These parameters are typically set by the developer based on the specific requirements of the game or graphics application.
Overall, depth bias is an important technique used in computer graphics to ensure smooth rendering of scenes by prioritizing objects based on their relative distance from the camera.

Etymology of DEPTH BIAS
The word "depth" comes from the Old English word "dēop", which means "deep". It has its roots in the Proto-Germanic word "deupaz". The word "bias", on the other hand, comes from the Middle French word "biais", which means "oblique". It has its origins in the Old Provençal word "biais", which is derived from the Late Latin word "badius".
When these two words are combined, "depth bias" refers to a tendency or inclination towards favoring or prioritizing information or perspectives that are deeper, more profound, or more detailed. This bias can influence how we perceive and interpret certain situations, leading us to give more weight or importance to things that are considered to be deeper in meaning or significance.
