Detailed Description

A Tile Renderer renders a number of tiles of an image by subTile. A Tile Renderer is created by calling I3DExFinalRenderer::GetTileRenderer() for each of the rendering thread.

Pseudo code to use a Tile Renderer:

    TMCCountedPtr<I3DExTileRenderer> tileRenderer;
    finalRenderer->GetTileRenderer(&tileRenderer);
    ThrowIfNil(tileRenderer);
    
    while (MoreTiles(&rect,&uvBox))
    {
        tileRenderer->Init(rect,uvBox);
    
        TMCRect subTileRect;
        while (tileRenderer->GetNextSubTile(subTileRect)
        {
            GetPixelPointers(pixels,subTileRect);
    
            tileRenderer->RenderSubTile(pixels);
            DisplaySubTile(rect);
        }
        GetTilePixels(pixels,TileRect);
        tileRenderer->FinishRender(pixels);
    }

Member Function Documentation

virtual void MCCOMAPI I3DExTileRenderer::FinishRender (  const RTData &  pixels  )  [pure virtual]

virtual boolean MCCOMAPI I3DExTileRenderer::GetNextSubTile (  TMCRect &  rect  )  [pure virtual]

Returns the next subTile to render (returns the same rectangle as long as RenderSubTile has not been called) Parameters: rect  The rectangle of the next sub Tile in pixel. Returns: True if there are more sub tiles to render, false if the last sub tile has already been rendered

virtual void MCCOMAPI I3DExTileRenderer::Init (  const TMCRect &  rect, const TBBox2D &  uvBox )  [pure virtual]

Initialiase the tileRenderer for the rendering of a new tile Parameters: rect  The rectangle of the tile to render (in pixels) uvBox  The screen coordinates of this tile

virtual void MCCOMAPI I3DExTileRenderer::RenderSubTile (  RTData &  pixels  )  [pure virtual]

Renders a sub tile of the current tile Parameters: pixels  Pointer to the pixels of the tile (color and GBuffers)
