Detailed Description

Class OpenGL_GAL is the OpenGL implementation of the Graphics Abstraction Layer.

This is a direct OpenGL-implementation and uses low-level graphics primitives like triangles and quads. The purpose is to provide a fast graphics interface, that takes advantage of modern graphics card GPUs. All methods here benefit thus from the hardware acceleration.

Constructor & Destructor Documentation

OPENGL_GAL::OPENGL_GAL ( GAL_DISPLAY_OPTIONS aDisplayOptions,
wxWindow *  aParent,
wxEvtHandler *  aMouseListener = nullptr,
wxEvtHandler *  aPaintListener = nullptr,
const wxString &  aName = wxT( "GLCanvas" ) 
)

Constructor OPENGL_GAL.

Parameters
aParentis the wxWidgets immediate wxWindow parent of this object.
aMouseListeneris the wxEvtHandler that should receive the mouse events, this can be can be any wxWindow, but is often a wxFrame container.
aPaintListeneris the wxEvtHandler that should receive the paint event. This can be any wxWindow, but is often a derived instance of this class or a containing wxFrame. The "paint event" here is a wxCommandEvent holding EVT_GAL_REDRAW, as sent by PostPaint().
aNameis the name of this window for use by wxWindow::FindWindowByName()

void OPENGL_GAL::DrawArcSegment ( const VECTOR2D aCenterPoint,

overridevirtual

Draw an arc segment.

This method differs from DrawArc() in what happens when fill/stroke are on or off. DrawArc() draws a "pie piece" when fill is turned on, and a thick stroke when fill is off. DrawArcSegment() with fill on behaves like DrawArc() with fill off. DrawArcSegment() with fill off draws the outline of what it would have drawn with fill on.

Parameters
aCenterPointis the center point of the arc.
aRadiusis the arc radius.
aStartAngleis the start angle of the arc.
aEndAngleis the end angle of the arc.
aWidthis the thickness of the arc (pen size).
