- class unreal.OptimusDataDomain¶
Bases:
StructBase
- A struct to specify the domain range of a resource buffer, as defined by compute kernels and data
interfaces. Data domains can be multi-dimensional, expression-based, or empty. Empty domains on pins imply a single value, like a parameter.
Domains come in two flavors, either as a pre-defined list with a multiplier, or as an arithmetic expression. For domains with a multiplier, the multiplier only applies to the innermost dimension (e.g. Vertex.Bone x 2, allows for two values per-bone, but not two values per-bone _and_ per-vertex)
The expression can take any execution domain, or none (e.g. “Vertex * 2 + 1”, “Triangle * 2 + Vertex * 6”, “1024”). If an expression is used, the domain is one-dimensional. As of now, expression domain comparison is done on the string level, such that “Vertex * 2” and “2 * Vertex” are not marked as compatible domains.
