Member Data Documentation

clearColor

SoSFColor ViewportRegion::clearColor

The color used when clearing color buffer. Default is (0,0,0).

clearColorBuffer

SoSFBool ViewportRegion::clearColorBuffer

Set to TRUE to clear color buffer for the new viewport when node is traversed.

clearDepthBuffer

SoSFBool ViewportRegion::clearDepthBuffer

Set to TRUE to clear depth buffer for the new viewport when node is traversed.

flipX

SoSFBool ViewportRegion::flipX

Invert the x coordinate. Normally x=0 is at the left, setting this to TRUE will make x=0 at the right.

flipY

SoSFBool ViewportRegion::flipY

Invert the y coordinate. Normally y=0 is at the bottom, setting this to TRUE will make y=0 at the top.

origin

SoSFVec2f ViewportRegion::origin

Origin of new viewport. (0,0) is lower left corner of current viewport. (1,1) is upper right. Default value is (0,0). The field last written into of origin and pixelOrigin will be used to set the origin when the node is traversed.

See also

pixelOrigin

pixelOrigin

SoSFVec2f ViewportRegion::pixelOrigin

Can be used to set origin directly, in pixels from lower left corner of viewport window. Default value is (0,0).

origin

pixelSize

SoSFVec2f ViewportRegion::pixelSize

Can be used to set size directly, in pixels. Default value is (128,128).

See also

size

size

SoSFVec2f ViewportRegion::size

Size of new viewport. (1,1) will create a viewport with the same size as the current. Default value is (1,1). The field last written into of size and pixelSize will be used to set the size when the node is traversed.

pixelSize
