Runtime Object Construction
Generally new objects of various kind can be created using Object Generator.
Creating New Entities
There are other ways of creating entities. One is via
IModel_DG.AddNew*() methods. Example:
IBRepSolid_DG iSolid = iModel_DG.AddNewBRepSolid();
IEntity_DG newEntity = iModel_DG.AddNewEntity(); newEntity.SetGeometryType("Mesh");
Or similar calls to IEntity_DG.AddNewChild*()
Standalone entities can be constructed with
IObjectGenerator_DG.Create("Entity_DG") call. Details
IStdShape_DG interface provides a
simplified way for creation of standard entities like Cylinder, Sphere, etc.
IDraw_DG provides another way for quickly building entities. This method is useful for creation of auxiliary objects, which show simple lines, curves or surface patches. IDraw_DG follows OpenGL Begin()/End() pattern
IScene_DG allows simple creation of entities, which present general (non-entity) geometric objects like box or sphere.
Creating Standalone Models
Standalone models can be constructed with
IObjectGenerator_DG.Create("Model_DG") call. Details
