Function documentation

TGLH2PolyPainter(TH1* hist, TGLPlotCamera* camera, TGLPlotCoordinates* coord)

Ctor.

char * GetPlotInfo(Int_t px, Int_t py)

Show number of bin and bin contents, if bin is under the cursor.

Bool_t InitGeometry()

Tesselate polygons, if not done yet.
All pointers are validated here (and in functions called from here).
If any pointer is invalid - zero, or has unexpected type (dynamic_cast fails) -
InitGeometry will return false and nothing will be painted later.
That's why there are no checks in other functions.

void StartPan(Int_t px, Int_t py)

User clicks on a lego with middle mouse button (middle for pad).

void Pan(Int_t px, Int_t py)

Mouse events handler.

void AddOption(const TString& stringOption)

No additional options.

void ProcessEvent(Int_t event, Int_t px, Int_t py)

No events.

void InitGL() const

Initialize some gl state variables.

void DeInitGL() const

Return some gl states to original values.

void DrawPlot() const

Draw extruded polygons and plot's frame.

void DrawExtrusion() const

Extruded part of bins.
GL_QUADS, GL_QUAD_STRIP - have the same time on my laptop, so I use
GL_QUADS and forgot about vertex arrays (can require more memory BTW).

void DrawExtrusion(const TGraph* polygon, Double_t zMin, Double_t zMax, Int_t nBin) const

Extrude polygon, described by TGraph.

void DrawExtrusion(const TMultiGraph* polygon, Double_t zMin, Double_t zMax, Int_t nBin) const

Multigraph contains a list of graphs, draw them.

void DrawCaps() const

Caps on bins.

void DrawCap(TGLH2PolyPainter::CIter_t cap, Int_t bin) const

Draw a cap on top of a bin.

Bool_t CacheGeometry()

Cache all data for TH2Poly object.

Bool_t BuildTesselation(Rgl::Pad::Tesselator& tess, const TGraph* g, Double_t z)

Tesselate a polygon described by TGraph.

Bool_t BuildTesselation(Rgl::Pad::Tesselator& tess, const TMultiGraph* mg, Double_t z)

Iterate over multi graph contents and tesselate nested TGraphs.

Bool_t UpdateGeometry()

Update cap's z-coordinates for all caps.
Here no pointers are checked, this was already done
by InitGeometry. So, if histogram was broken somehow
- hehe, good luck.

void SetBinColor(Int_t bin) const

Set bin's color.

void DrawSectionXOZ() const

No sections.

void DrawSectionYOZ() const

No sections.

void DrawSectionXOY() const

No sections.

void DrawPalette() const

Not yet.

void DrawPaletteAxis() const

Not yet.

void FillTemporaryPolygon(const Double_t* xs, const Double_t* ys, Double_t z, Int_t n) const

Since I probably have to re-orient polygon, I need a temporary polygon.

void MakePolygonCCW() const

Code taken from the original TH2Poly.

Bool_t ClampZ(Double_t& zVal) const

Clamp z value.
