Member Function Documentation

bool CUI_PolyEdgeBorder::GetBorder (  double  dtime, v2_fp &  vlist, int &  numvert, unsigned short &  primitivetype )  [virtual]

returns a list of 2d vertices and UI_POLYGON This should do as a general purpose primitive, but a more sophisticated tesselating algorithm may be required for more complex shapes. Parameters: dtime  current time (for animation) vlist  pointer to hold the list of vertices numvert  integer to hold the number of vertices in the list primitivetype  to hold the type of primitive needed to render the list See also: UI_TRIANGLE_STRIP UI_QUAD_STRIP UI_TRIANGLE_FAN UI_POLYGON Implements IUI_Border.

bool CUI_PolyEdgeBorder::GetOutline (  double  dtime, v2_fp &  vlist, int &  numvert )  [virtual]

returna list of 2d vertices that if drawn with UI_LINE_LOOP will produce the outline See also: GetBorder UI_LINE_LOOP Implements IUI_Border.

bool CUI_PolyEdgeBorder::SetBorder (  v2_f *  vlist, int  numvert )  [virtual]

Defines the border by a list of vertices in counter-clockwise order. Assumes that vertices are in counter-clockwise order and form a convex polygon. Parameters: vlist  array of 2d vertices (x, y in local space) numvert  number of vertices in vlist Implements IUI_Border.

bool CUI_PolyEdgeBorder::TestHit (  float  x, float  y )  [virtual]

Test to see if a given point is within this boundary. Parameters: x  x position (in local space) y  y position (in local space) Returns: true if the point is within the boundary Implements IUI_Border.
