MVG Nodes

MVG Nodes can be created in CGI Studio SceneComposer via the Toolbox. Simply drag and drop the desired MVG Node into the Scene Editor or Scene Tree Panel.

The following MVG Nodes are available:

• MVG Arc Node

• MVG Ellipse Node

• MVG Path Node

• MVG Rect Node

You can see an application of MVG nodes in Scene Composer's 2D Basic sample.

Configure MVG Nodes

An MVG node is a RenderNode2D and therefore it has the same properties that can be configured in the properties panel:

• General. Name, Full Name, Description...
  
• 2D Render Node: Render Order Rank...
  
• Transformation: Position, Pivot Point, Pivot Offset...
  
• Asset: Id, Symbolic Name...
  
• Item: Scope Mask, Alpha Value...
  
• Layout: Vertical Alignment, Horizontal Alignment, Size...

Further details like the visual appearance of MVG nodes can be configured in the node's effect. Each type of MVG node has its appropriate effect:

MVG Node	MVG Brush
MVG Arc Node	MVG Arc BrushMVGArcBrush
MVG Ellipse Node	MVG Ellipse BrushMVGEllipseBrush
MVG Path Node	MVG Path BrushMVGPathBrush
MVG Rect Node	MVG Rect BrushMVGRectBrush

Select the MVG Node in the Scene Tree and select the attached MVG effect in the right side of the Scene Tree to view its properties in the properties panel.

MVG Arc Node - MVGArcBrush

Can be used to displayrender an arc.

The properties of the MVG Arc Node are those of a regular RenderNode2dD.RenderNode2D. InFor the propertiesattached ofeffect the MVG Arc Brush,MVGArcBrush, the following properties can be configured.configured:

Filter	filterFilter for rendering (choose between BilinearFilter and NearestFilter) .
Line Width	widthWidth of the rendered line in pixels pixels.
Stroke Color	colorColor of the rendered line line.
Size	verticalVertical (X) and horizontal (Y) size of the arc to be renderedrendered.
Angle Start	theThe angle of the arc's starting pointpoint.
Angle End	theThe angle of the arc's end point point.

The arcs starting and end point hashave to be entered as in degrees. Please also see the sketch below.

MVG Ellipse Node - MVGEllipseBrush

Can be used to displayrender an ellipse.

The properties of the MVG Ellipse Node are those of a regular RenderNode2dD. InFor the propertiesattached ofeffect the MVG Ellipse Brush,MVGEllipseBrush, the following properties can be configured.configured:

Filter	filterFilter for rendering (choose between BilinearFilter and NearestFilter) .
Line Width	widthWidth of the rendered line in pixels pixels.
Stroke Color	colorColor of the rendered line line.
Size	verticalVertical (X) and horizontal (Y) size of the arc to be renderedrendered.
Angle Start	theThe angle of the ellipse's starting pointpoint.
Angle End	theThe angle of the ellipse's end point point.
FillColor	fillFill color of the ellipse  ellipse.
PaintMode	configuresConfigures if the ellipse will be rendered with outline and filling or with either of those (choose between Both, Fill and Stroke) .

MVG Path Node - MVGPathBrush

Can be used to displayrender paths with a combination of instructions.

The properties of the MVG Path Node are those of a regular RenderNode2dD. InFor the propertiesattached ofeffect the MVG Path Brush,MVGPathBrush, the following properties can be configuredconfigured:

Filter	filterFilter for rendering (choose between BilinearFilter and NearestFilter) .
LineWidth	widthWidth of the rendered line in pixels pixels.
Stroke Color	colorColor of the rendered line line.
FillColor	fillFill color of the path path.
PaintMode	configuresConfigures if the path will be rendered with outline and filling or with either of those (choose between Both, Fill and Stroke) .
Segments	Defines segments. Input value VGPathSegment number of Data Description 0 ClosePath 0 Closing a path by connecting a final coordinate to a start coordinate. Therefore, the required number of Data is 0. 2 MoveTo 2 Specify coordinates of a path starting point. Therefore, the required number of Data is two (x0, y0). 4 LineTo 2 Draws a straight line. Specify an end point coordinates. Therefore, the required number of Data is two (x0, y0). A straight line is drawn from a coordinates specified in the previous Segment to a coordinates specified in this Segment. 6 HLineTo 1 Draws a horizontal line. The required number of Data is only one (x0). 8 VLineTo 1 Draws a vertical line. The required number of Data is only one (y0). 10 QuadTo 4 Draws a quadratic Bezier curve. Specify a coordinates of a control point and an end point. Therefore, the required number of Data is 4 (x0, y0, x1, y1). Please refer the below image as an example. 12 CubicTo 6 Draws a cubic Bezier curve. Specify coordinates of two control points and an end point. Therefore, the required number of Data is 6 (x0, y0, x1, y1, x2, y2). Please refer the below image as an example.
Data	Defines Data according to the specified Segment.

MVG Rect Node - MVGRectBrush

Can be used to displayrender a rect.

The properties of the MVG Rect Node are those of a regular RenderNode2dD. InFor the propertiesattached of the MVG Rect Brush,MVGRectBrush, the following properties can be configured.configured:

Filter	filterFilter for rendering (choose between BilinearFilter and NearestFilter) .
LineWidth	widthWidth of the rendered line in pixels pixels.
Stroke Color	colorColor of the rendered line line.
Size	verticalVertical (X) and horizontal (Y) size of the arc to be rendered
TopLeftRadius	radiusRadius of the top left corner.
TopRightRadius	radiusRadius of the top right corner corner.
BottomLeftRadius	radiusRadius of the bottom left corner corner.
BottomRightRadius	radiusRadius of the bottom right corner corner.
FillColor	fillFill color of the path path.
PaintMode	configuresConfigures if the rectangle will be rendered with outline and filling or with either of those (choose between Both, Fill and Stroke) .
