DrawContext Class

Draw Context Class

A class that provides drawing functionality for use by IDirectContext3DServer servers
Inheritance Hierarchy
System Object
Autodesk.Revit.DB.DirectContext3D DrawContext

Namespace: Autodesk.Revit.DB.DirectContext3D
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public static class DrawContext

The DrawContext type exposes the following members.

Methods
Name Description
Public method Static member FlushBuffer Submits geometry for rendering.
Public method Static member GetCamera Gets the camera corresponding to the Revit view where rendering takes place.
Public method Static member GetClipPlanes Gets the clipping planes for the Revit view where rendering takes place. Clipping planes control the 3D extent of a view and can be set using Section Box in Revit.
Public method Static member GetClipRectangle Gets the clip rectangle for the Revit view where rendering takes place. The clip rectangle is the area currently being redrawn, which may be smaller than the view rectangle.
Public method Static member GetOverrideColor Returns override color that will be applied to geometry during rendering.
Public method Static member GetOverrideTransparency Returns override transparency that will be applied to geometry during rendering.
Public method Static member GetViewRectangle Gets the rectangle that represents the extent (in 2D) of the Revit view where rendering takes place.
Public method Static member IsAvailable Checks whether the facilities of this class are available for use in the current scope.
Public method Static member IsInterrupted Checks whether the current rendering pass has been interrupted.
Public method Static member IsTransparentPass Determines whether the current rendering pass is for transparent objects.
Public method Static member SetWorldTransform Sets the world transformation that will be applied to geometry during rendering.

Remarks

The drawing facility of this class is conceptually similar to a low-level graphics API. The functionality operates on a set of geometry primitives such as triangles, lines, and points, which are encoded into a set of vertex and index buffers.

Aside from submission of geometry in buffers, a major part of the drawing process is responding to certain changes in graphics state. For example, users of this class can implement progressive rendering of geometry by testing whether there have been interruptions that should prevent the drawing from being completed.
