Detailed Description

View abstract class

The IvfView class is an abstract class for implementing different cameras. The viewTransform and projectionTransform methods should be overidden.

Member Function Documentation

void CIvfView::beginTransform (   )  [protected, virtual]

Start transform Implements a OpenGL transform. This routine should call a glPushMatrix() and then call OpenGL routines transforming the object. The method is the first routine to be called in the render() method. Reimplemented from CIvfObject.

double CIvfView::getAspect (   )

Return current aspect ratio.

virtual void CIvfView::getViewFrustum (  CIvfViewFrustum *  frustum  )  [virtual]

Return view frustum This method should modify the frustum parameter to reflect the currently used view frustum. Method is overidden by descendant classes. Reimplemented in CIvfCamera.

void CIvfView::getViewPort (  int &  tx, int &  ty, int &  tw, int &  th )

Returns view port dimension

void CIvfView::getViewPort (  int &  w, int &  h )

Returns view port dimension

virtual void CIvfView::initialize (   )  [virtual]

Initialize perspective and viewport This method must be called before the camera can be used to view a scene. Typically it is called in a GLUT reshape callback.

virtual void CIvfView::initializeSelect (  int  x, int  y, int  w, int  h )  [virtual]

Initialize selection This method is used to setup the pick matrix used for object selection in OpenGL based on the current camera view. Parameters: x  X coordinate for selection point (pixels). y  Y coordinate for selection point (pixels). w  Width of selection box. h  Height of selection box.

void CIvfView::setViewPort (  int  tx, int  ty, int  tw, int  th )

Returns view port dimension

void CIvfView::setViewPort (  int  width, int  height )

Set viewport dimension. The viewport is defined in screen pixels. Viewport dimension is used to calculate the view aspect ratio. Parameters: width  View width in pixels height  View height in pixels
