Hyper Parameters
Parameters you set during the training. Not the parameters of the model that is generated.
Epoch (Machine Learning)
One full pass on the training data. There may be more, that would be multi epochs for training.
ML training with multiple features (general knowledge)
When ML training using more than one feature. It is best to have the values of the metrics be similar in scale (because math).
PBR (When it comes to 3d Assets)
Physically Based Rendering
Albedo Map
True color without lighting effects
Roughness Map
micro surface
shiny vs. matte
Normal Map
Adds fine surface details w/o increasing poly count
Ambient Occlusion (AO) Map
Simulates how light is occluded in crevices adding depth and realism
Height Map
Adds actual displacement of geometry for more pronounced depth effects
Metallic Map
Reflective (metal) vs. Diffuse (non-metal)
MDL
Material Definition Language:
Standardized, high-level programming language designed to describe the appearance and behavior of materials in physically-based rendering systems.
MaterialX
Open-source standard for defining and exchanging materials and their associated shading networks across different software tools and rendering engines. Developed by Industrial Light & Magic (ILM), it is widely used in industries like visual effects, gaming, and design to ensure consistency and interoperability of materials.
Wiki Q-codes semantic labels
To standardize semantic labels across different platforms and languages, the open-source database Wikidata is often utilized. Wikidata assigns unique alphanumeric identifiers, known as Q-codes or QIDs, to represent specific concepts or objects. For example, the QID Q42889 corresponds to the concept of a “car.” By embedding these Q-codes into 3D assets, creators can ensure consistent identification and interpretation across various systems and languages.
