DG Kernel (ActiveX) Documentation

IDraw_DG allows adding quickly simple entities following OpenGL syntax. Such entites are used normaly as auxiliary items. In other words it is an interface to draw into a model

By default the entities created via Begin(); ...Vertex();...End(); are transient, i.e. they are not saved with the model, which can be changed by calling SetTransient() prior the creation. See also Transient Flag

IDraw_DG can be queried from IModel_DG. See also: Metrics sample

bool IsEyeFrameSpace()

Returns value of EyeFrameSpace flag. When EyeFrameSpace is set, the entity created with this interface will be aligned to Eye Frame and all coordinates are assumed relative to the Eye Frame

void SetEyeFrameSpace(bool val)

When EyeFrameSpace flag is set, the entity created with this interface will be aligned to Eye Frame and all coordinates are assumed relative to the Eye Frame

bool IsTransient()

By default the entities created via Begin(); ...Vertex();...End(); are transient, i.e. they are not saved with the model. Call this method to change this behaviour. See also Transient Flag

void SetTransient(bool val)

Sets the default Transient Flag for new entities. True is the default
