DisplayPipeline

DisplayPipeline class

The display pipeline calls events during specific phases of drawing During the drawing of a single frame the events are called in the following order. [Begin Drawing of a Frame]

CalculateBoundingBox
CalculateClippingPanes
SetupFrustum
SetupLighting
InitializeFrameBuffer
DrawBackground
If this is a layout and detail objects exist the channels are called in the same order for each detail object (drawn as a nested viewport)
PreDrawObjects
For Each Visible Non Highlighted Object
- SetupObjectDisplayAttributes
- PreDrawObject
- DrawObject
- PostDrawObject
PostDrawObjects - depth writing/testing on
DrawForeGround - depth writing/testing off
For Each Visible Highlighted Object
- SetupObjectDisplayAttributes
- PreDrawObject
- DrawObject
- PostDrawObject
PostProcessFrameBuffer (If a delegate exists that requires this)
DrawOverlay (if Rhino is in a feedback mode)

[End of Drawing of a Frame] NOTE: There may be multiple DrawObject calls for a single object. An example of when this could happen would be with a shaded sphere. The shaded mesh is first drawn and these channels would be processed; then at a later time the isocurves for the sphere would be drawn.

Properties (28)

ActiveObject

ActiveObjectNestingLevel

ActiveObjectNestingStack

ActiveTopLevelObject

DefaultCurveThickness

Gets the curve thickness as defined by the current display mode. Note: this only applies to curve objects, Brep and Mesh wires may have different settings.

DepthMode

DisplayPipelineAttributes

DpiScale

Scale factor used for high resolution displays. When a monitor that this pipeline is drawing to is at a DPI of 96, this value is one. On high DPI monitors, this value will commonly be greater than one.

DrawingGrips

Gets a value that indicates whether the pipeline is currently in a grip drawing operation.

DrawingSurfaces

Gets a value that indicates whether the pipeline is currently in a surface drawing operation. Surface drawing means draw the shaded triangles of a mesh representing the surface (mesh, extrusion, or brep). This is useful when inside of a draw event or display conduit to check and see if the geometry is about to be drawn as a shaded set of triangles representing the geometry. See DrawingWires to check and see if the wireframe representation of the geometry is going to be drawn.

DrawingWires

Gets a value that indicates whether the pipeline is currently in a curve drawing operation. This is useful when inside of a draw event or display conduit to check and see if the geometry is about to be drawn is going to be drawing the wire representation of the geometry (mesh, extrusion, or brep). See DrawingSurfaces to check and see if the shaded mesh representation of the geometry is going to be drawn.

FrameBuffer

Gets the contents of the frame buffer that this pipeline is drawing to.

FrameSize

Gets the size of the frame buffer that this pipeline is drawing to.

IsDynamicDisplay

Gets a value that indicates whether the viewport is in Dynamic Display state. Dynamic display is the state a viewport is in when it is rapidly redrawing because of an operation like panning or rotating. The pipeline will drop some level of detail while inside a dynamic display state to keep the frame rate as high as possible.

IsInViewCapture

Gets a value that indicates whether this pipeline is currently drawing for ViewCaptureToFile or ViewCaptureToClipboard

IsOpen

Is True of the pipeline is open, False otherwise.

IsOpenGL

Gets a value indicating whether or not this pipeline is drawing into an OpenGL context.

IsPrinting

Gets a value that indicates whether this pipeline is currently drawing for printing purposes.

IsStereoMode

Gets a value that indicates whether this pipeline is currently using an engine that is performing stereo style drawing. Stereo drawing is for providing an "enhanced 3-D" effect through stereo viewing devices.

ModelTransform

Gets or sets the current model transformation that is applied to vertices when drawing.

ModelTransformIsIdentity

Gets a value that indicates whether the Model Transform is an Identity transformation.

NestLevel

Gets the current nested viewport drawing level. This is used to know if you are currently inside the drawing of a nested viewport (detail object in Rhino).
Nest level = 0 Drawing is occurring in a standard Rhino viewport or on the page viewport.
Nest level = 1 Drawing is occurring inside a detail view object.

RenderPass

Gets the current pass that the pipeline is in for drawing a frame. Typically drawing a frame requires a single pass through the DrawFrameBuffer function, but some special display effects can be achieved through drawing with multiple passes.

ShadingRequired

Gets or sets the "ShadingRequired" flag. This flag gets set inside the pipeline when a request is made to draw a shaded mesh but the current render engine doesn't support shaded mesh drawing...at this point the redraw mechanism will make sure everything will work the next time around.

StereoProjection

Gets the current stereo projection if stereo mode is on.
0 = left
1 = right If stereo mode is not enables, this property always returns 0.

SupportsShading

Gets whether or not this pipeline supports shaded meshes.

InterruptDrawing()

Tests to see if the pipeline should stop drawing more geometry and just show what it has so far. If a drawing operation is taking a long time, this function will return True and tell Rhino it should just finish up and show the frame buffer. This is used in dynamic drawing operations.

IsActive(RhinoObject rhinoObject)

Determines if an object can be visible in this viewport based on it's object type and display attributes. This test does not check for visibility based on location of the object. NOTE: Use CRhinoDisplayPipeline::IsVisible() to perform "visibility" tests based on location (is some part of the object in the view frustum). Use CRhinoDisplayPipeline::IsActive() to perform "visibility" tests based on object type.

IsInTiledDraw(Size fullSize,Rectangle currentTile)

Returns True if the currently drawn frame is part of a tiled capture. Tiled captures are performed when creating large raster outputs.

IsVisible(RhinoObject rhinoObject)

This function calls a virtual IsVisibleFinal function that sub-classed pipelines can add extra tests to. In the base class, this test only tests visibility based on the objects world coordinates location and does not pay attention to the object's attributes. NOTE: Use CRhinoDisplayPipeline::IsVisible() to perform "visibility" tests based on location (is some part of the object in the view frustum). Use CRhinoDisplayPipeline::IsActive() to perform "visibility" tests based on object type.

Events (13)

CalculateBoundingBox

CalculateBoundingBoxZoomExtents

Calculate a bounding to include in the Zoom Extents command.

DisplayModeChanged

DrawForeground

Called after all non-highlighted objects have been drawn and PostDrawObjects has been called. Depth writing and testing are turned OFF. If you want to draw with depth writing/testing, see PostDrawObjects.

DrawOverlay

InitFrameBuffer

ObjectCulling

PostDrawObject

Called right after an individual object has been drawn. NOTE: Do not use this event unless you absolutely need to. It is called for every object in the document and can slow display down if a large number of objects exist in the document

PostDrawObjects

Called after all non-highlighted objects have been drawn. Depth writing and testing are still turned on. If you want to draw without depth writing/testing, see DrawForeground.

PreDrawObject

Called right before an individual object is being drawn. NOTE: Do not use this event unless you absolutely need to. It is called for every object in the document and can slow display down if a large number of objects exist in the document

PreDrawObjects

Called before objects are been drawn. Depth writing and testing are on.

PreDrawTransparentObjects

Called before transparent objects have been drawn. Depth writing and testing are on.
