GVROrthoOverlay

Purpose

The module GVROrthoOverlay displays an overlay on a 2D viewer that can even be an OrthoView2D.

Details

Internally, the macro makes use of the SoGVRVolumeRenderer. Due to this, the entire image is converted into an octree before displaying it. Thus, if this macro module is used for displaying only one slice (on a ‘normal’ 2D viewer), it can become inefficient to the point of being useless. Use a standard SoView2DOverlay instead.

Use LUT from scene

name: useSceneLut, type: Bool, default: FALSE

If checked, the LUT present in the scene is used to color the overlay. Otherwise, an internal LUT is used.

Center

name: lutCenter, type: Float, default: 0.5, minimum: 0, maximum: 1

Sets the center value of the internal LUT.

Width

name: lutWidth, type: Float, default: 0.5, minimum: 0, maximum: 1

Sets the width value of the internal LUT.

Base Color

name: baseColor, type: Color, default: 0.356862992048264 1 0.058823499828577

Sets the base color of the internal LUT.

Base Alpha

name: baseAlpha, type: Float, default: 0.54799998, minimum: 0, maximum: 1

Sets the base alpha value of the internal LUT.

Time point

name: currentTimePoint, type: Integer, default: 0, minimum: 0, maximum: SoGVRVolRen.maxTimePoint

Sets the temporal position that is rendered.

Hidden Fields

clipToSlice

name: clipToSlice, type: Bool, default: TRUE
