TGLHistPainter

Class Description

Each TGLHistPainter has default painter as a member
to delegate unsupported calls

~TGLHistPainter()

Destructor

Int_t DistancetoPrimitive(Int_t px, Int_t py)

If fLastOption != kUnsupported, try to select hist or axis.
If not - gPad is selected (there are problems with TF2)

void DrawPanel()

Interface to DrawPanel

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

If fLastOption == kUnsupported, delegate call.
If not, try to process itself

void FitPanel()

to be FIXed

TList * GetContourList(Double_t contour)

char * GetObjectInfo(Int_t px, Int_t py)

Bool_t IsInside(Int_t x, Int_t y)

to be FIXed

Bool_t IsInside(Double_t x, Double_t y)

void PaintStat(Int_t dostat, TF1 *fit)

to be FIXed

void ProcessMessage(const char *mess, const TObject *obj)

to be FIXed

void SetHistogram(TH1 *hist)

to be FIXed

void SetStack(TList *stack)

to be FIXed

Int_t MakeCuts(char *cutsOpt)

to be FIXed

void Paint(Option_t *o)

Final-overrider for TObject's Paint

void Paint()

This function indirectly called via gGLManager->PaintSingleObject

void PrintPlot()

 Generate PS using gl2ps

Bool_t SetVertices()

Set axes ranges, vertices, normals

Bool_t SetAxes()

Having TH1 pointer, setup min/max sizes and scales

void AdjustScales()

Finds the maximum dimension and adjust scale coefficients

void SetTable()

Calculates table of X and Y for lego (Z is obtained during drawing) or
calculate mesh of triangles with vertices in the centres of bins

void SetMesh()

Calculates table of X and Y for lego (Z is obtained during drawing) or
calculate mesh of triangles with vertices in the centres of bins

void SetTF3Mesh()

Build mesh for TF3 surface

void SetNormals()

Calculates normals for triangles in surface.
we have four points (cell contents of four neighbouring hist bins),
three points are in one plane, so build normals for 2 triangles

void SetAverageNormals()

One normal per vertex;
this normal is average of
neighbouring triangles normals

void InitGL()

gl initialization (Disable/Enable)

Bool_t MakeCurrent()

Check gl context and make it current

void DrawLego()

Draws lego

void DrawSurface()

Draw surf/surf1/surf2/surf4

void DrawTF3()

Draw TF3 surface

void CalculateTransformation()

Sets viewport, bounds for arcball
Calculates arguments for glOrtho
Claculates center of scene and shift

void DrawFrame()

Draws frame box around hist or surface,
draws grids and 'profiles'
Planes are 85% opaque to make their color "softer"

void SetCamera()

Viewport and projection

void SetTransformation()

Applies rotations and translations before drawing

Int_t FrontPoint()

Converts 3d points into window coordinate system
and find the nearest

void DrawBackPlane(Int_t plane)

Draw back plane with number 'plane'

void DrawAxes()

Using front point, find, where to draw axes and which labels to use for them
gVirtualX->SelectWindow(gGLManager->GetVirtualXInd(fGLDevice));

Bool_t Select(Int_t x, Int_t y)

Find hist "square" on screen

void SelectAxes(Int_t front, Int_t x, Int_t y)

Checks, if axis can be selected

void DrawZeroPlane()

Blue, semi-transparent plane at zero-level

void DrawProfile(Int_t plane)

Draw "shadows" for lego/surf

void DrawLegoProfileX(Int_t plane)

Draws X lego's profile on 'plane'
for each 'row' find min and max
and draw them as rectangle

void DrawLegoProfileY(Int_t plane)

Draws Y lego's profile on 'plane'
for each 'column' find min and max
and draw them as rectangle

void DrawSurfaceProfileX(Int_t plane)

Draws X surface's profile on 'plane'

void DrawSurfaceProfileY(Int_t plane)

Draws Y surface's profile on 'plane'

void SetZLevels()

Define levels for grid

void DrawGrid(Int_t plane)

Grid at XOZ or YOZ back plane
Under win32 glPushAttrib does not help with GL_LINE_STIPPLE enable bit

void ClearBuffers()

Clears gl buffers

void Pan(Int_t x, Int_t y)

 Panning

void SetTexture()

Set default texture

void SetPlotColor()

Set color for lego/surface

void EnableTexture()

Enable 1D texture

void DisableTexture()

Disable 1D texture

TGLHistPainter(TH1 *hist)

EGLPaintOption SetPaintFunction(TString &option)

Bool_t Select(Int_t x, Int_t y)
