Constructor & Destructor Documentation

◆ TGLClipPlane()

TGLClipPlane::TGLClipPlane ( )

Fixed color of clip plane.

Construct a clip plane object, based on supplied 'plane', with initial manipulation pivot at 'center', with drawn extents (in local x/y axes) of 'extents'.

Plane can have center pivot translated in all directions, and rotated round center in X/Y axes , the in-plane axes. It cannot be scaled

Note theoretically a plane is of course infinite - however we want to draw the object in viewer - so we fake it with a single GL face (polygon) - extents defines the width/depth of this - should be several times scene extents - see Setup().

Definition at line 161 of file TGLClip.cxx.

◆ ~TGLClipPlane()

TGLClipPlane::~TGLClipPlane ( )
virtual

Destroy clip plane object.

Definition at line 174 of file TGLClip.cxx.

Member Function Documentation

◆ PlaneSet()

void TGLClipPlane::PlaneSet ( TGLPlaneSet_t set) const
virtual

Return set of planes (actually a single one) describing this clip plane.

Implements TGLClip.

Definition at line 242 of file TGLClip.cxx.

◆ Set()

void TGLClipPlane::Set ( const TGLPlane plane)

Update clip plane object to follow passed 'plane' equation.

Center pivot is shifted to nearest point on new plane.

Definition at line 230 of file TGLClip.cxx.

◆ Setup() [1/2]

void TGLClipPlane::Setup ( const TGLBoundingBox bbox)
virtual

Setup the clip object for scene encompassed by bbox.

Implements TGLClip.

Definition at line 181 of file TGLClip.cxx.

◆ Setup() [2/2]

void TGLClipPlane::Setup ( const TGLVector3 point,
const TGLVector3 normal 
)
virtual

Setup the clipping plane by point and normal.

Length of the normal determines the size of the plane drawn in GL viewer. The normal points into the direction of visible half-plane.

This only makes sense if you disable auto-update of the clip-object:

gl_viewer->SetClipAutoUpdate(kFALSE).

After calling this also call gl_viewer->RefreshPadEditor(gl_viewer) and gl_viewer->RequestDraw().

Reimplemented from TGLClip.
