Detailed Description

GlObject to render a label map into a GlSliceView using isolines.

The current implementation only supports label maps of unsigned byte type.

Note: This class trades performance for accuracy and will only render an approximation of the isolines. If you need pixel-perfect isolines, you will need to run marching squares yourself and render the resulting geometry as lines.

Member Function Documentation

◆ setColors()

void setColors ( std::vector< vec4f > colorMap )

Sets the color map to use for label rendering.

Note: To maintain backward-compatibility, the colorMap will apply to the value range of [1 .. colorMap.size()], i.e. a label map value of 0 will always be fully transparent when using this function.

◆ draw()

void draw ( const GlView & view )

overridevirtual

Draw the object in 3D space.

Implements GlObject.

◆ bounds()

Geometry::AlignedBox bounds ( ) const

overridevirtual

Get the axis-aligned bounding box of this GlObject in world space.

Return an empty (default-constructed) AlignedBox object if the GlObject does not reside in world space.

Implements GlObject.

◆ typeName()

std::string typeName ( ) const

overridevirtual

Return unique identifier for this object class used for serialization.

Implements GlObject.
