SoSFEnum components
Components to get back from the offscreen render.
SoSFBool trigger
Setting this field to TRUE will start the off-screen rendering process.
SoSFVec3i32 boxSize
Resolution of the output data in the off-screen box.
SbVec3i32 getMaxBoxSize(SoState *state=NULL)
Returns the maximum boxSize that can be extract in one boxComputed for the current state.
bool synchronousExtraction(SoSceneManager *sceneManager)
Does extraction synchronously, whereas using trigger field will execute extraction on next redraw.
SoSFFloat opacityThreshold
During extraction, voxels with an opacity less than the specified value will be ignored Default is 0.
