HiddenLineAttributeControl

class HPS.HiddenLineAttributeControl : HPS.Control 

The HPS.HiddenLineAttributeControl class is a smart pointer that is tied to a database object. This control allows you to manipulate the various attributes associated with hidden lines. Hidden line is a rendering mode that applies to the scene as a whole. You should not set disparate hidden line attributes in your scene.

This table lists default values for the various segment attributes accessible from HPS.HiddenLineAttributeControl.

Public Functions

override void Dispose ()

HiddenLineAttributeControl (HPS.HiddenLineAttributeControl in_that): Initializes a control tied to the same object as in_that.

HiddenLineAttributeControl (HPS.SegmentKey in_seg): Initializes a control tied to the segment in_seg.

override HPS.Type ObjectType ()

This function returns the type the object, as declared (if the object is derived, this does not give the true type of the derived object).

Return:	The declared type of the object in question, which may differ from the true, underlying type.

HPS.HiddenLineAttributeControl SetAlgorithm (HPS.HiddenLine.Algorithm in_algorithm)

Specifies the sorting algorithm that should be used to sort faces that have been made visible by the SetRenderFaces method. Default is ZBuffer.

Param in_algorithm:
	The algorithm used to sort visible faces.
Return:	A reference to this object.

HPS.HiddenLineAttributeControl SetColor (HPS.RGBAColor in_color)

Sets the color to be applied to the hidden lines and markers.

Param in_color:	The color hidden line geometry should be drawn in.
Return:	A reference to this object.

HPS.HiddenLineAttributeControl SetDimFactor (float in_zero_to_one)

Specifies the fraction of the current line color’s R, G, and B channels to use for the color of hidden lines and markers. By default, Visualize will automatically take a fraction of the RGB values to darken the hidden lines and markers.

Return:	A reference to this object.

HPS.HiddenLineAttributeControl SetFaceDisplacement (float in_buckets)

Note: hidden line face displacement is separate from the general face displacement value set with the DrawingAttributeKit.SetFaceDisplacement.

Param in_buckets:
	The number of units to move faces in the Z-Buffer. The units are 1/2^24 in the normalized depth range [0,1]. Negative values will move faces toward the camera, positive values away from the camera.
