DCInternalViewPort (DCInternalViewPort *_pFather)

Constructor.

virtual ~DCInternalViewPort ()

Destructor. See DeleteViewport().

virtual void Clear (float _red=0.0f, float _green=0.0f, float _blue=0.0f)

Reset color to black (or given color),and depth buffer, of this ViewPort.

virtual void RenderMesh (InternalObject3DBuffer *_pMeshBuffer, InternalTexture *_pTexture=0L)

Render a 3D Object. The vertexes are transformed with matrix _pMatrix, the object shape is defined by _pMeshBuffer, the texture of the object is defined by _pTexture, the ViewPort that define the rectangle where to draw, and the camera parameters is _pViewPort, or the default viewport if not specified. Note drawings on the main screen needs a SwapScreenBuffer() to be shown at each frames.

virtual void DrawRGBARectangle (unsigned char *_prgbaTable, unsigned int _PixelWidth, unsigned int _PixelHeight)

Render directly a 32bit pixel bitmap image from memory on a viewport. Note drawings on the main screen needs a SwapScreenBuffer() to be shown at each frames.

virtual void SwapBuffer ()

Swap buffer so that what was drawn on the viewport is shown. this is needed to active all Clear(), RenderMesh() ,... It has to be done with main screen viewport like texture-rendering viewports.

void ResetRootPixelSize (unsigned int _pixelWidth, unsigned int _pixelHeight)

Change the root viewport pixel resolution.This is a low level call in case of resize or screen init.

int GetPixelX1 ()

get the rectangle pixel coordinates in the root viewport bitmap.

int GetPixelY1 ()

get the rectangle pixel coordinates in the root viewport bitmap.

int GetPixelX2 ()

get the rectangle pixel coordinates in the root viewport bitmap.

int GetPixelY2 ()

get the rectangle pixel coordinates in the root viewport bitmap.

float GetFov ()

for 3D rendering, Distance between the projected plane and the center. must be >0.001

float GetNearCutPlane ()

float GetFarCutPlane ()

virtual void Matrix_LoadID (eLoadId _enum=eLoadId_All)

Tool for other methods: Set the current GL viewport matrix to an InternalViewPort.
