Describes an object or shape within an OMF file, and links to attributes that attach data to it.
Fields
- name:
const char * - Element name, which should be unique.
- description:
const char * - Optional element description or comments.
- color_set:
bool - Whether
colorshould be used. - color:
uint8_t[3] - Optional solid RGB color of the element.
- opacity:
double - Element opacity, from 0.0 for transparent to 1.0 for opaque.
- n_metadata:
size_t - Number of metadata items.
- metadata:
const OmfValue * - Pointer to an array of
n_metadatametadata items, forming a set of key/value pairs. - n_attributes:
size_t - Number of attributes.
- attributes:
const OmfAttribute * - Pointer to an array of
n_attributesattributes on this element. - point_set:
const OmfPointSet * - line_set:
const OmfLineSet * - surface:
const OmfSurface * - grid_surface:
const OmfGridSurface * - block_model:
const OmfBlockModel * - composite:
const OmfComposite * - Exactly one of these must be non-null. This defines the type of geometry the element has and contains the details of it.
