Member Function Documentation

virtual void ClearTriangles ( )

pure virtual

Clear all triangles gathered.

virtual tU32 GetNumTriangles ( ) const

pure virtual

Get the number of triangles gathered. {Property}.

virtual tVec3fCVec* GetTrianglesVertex ( ) const

pure virtual

Get the triangles vertices. {Property}.

virtual tU32CVec* GetTrianglesIndex ( ) const

pure virtual

Get the triangle indices. {Property}.

virtual void SetFlags ( tCollideQueryTrianglesFlags  aFlags )

pure virtual

Set the query's flags. {Property}.

Remarks

Default is 0.

virtual tCollideQueryTrianglesFlags GetFlags ( ) const

pure virtual

Get the query's flags. {Property}.

virtual tVec4fCVec* GetClippingPlanes ( ) const

pure virtual

Get the query's clipping planes. {Property}.

Remarks

The clipping planes should be in world space when clipping objects and in shape space when clipping shapes.

Default is zero planes.

virtual void SetCullingView ( const sVec4f &  avDirE )

pure virtual

Set the query's culling direction and epsilon. {Property}.

Remarks

The format of the parameters is a 4D vector (Dir.x,Dir.y,Dir.z,Epsilon).

Culling does : reject triangle if (VecDot(currentTriangle.normal,Dir) < Epsilon).

Default is Vec4(0,0,0,0).

virtual sVec4f GetCullingView ( ) const

pure virtual

Get the query's culling direction and epsilon. {Property}.

virtual void SetCullingClassify ( tU32  aClassify )

pure virtual

Set the cull planes classification flags. {Property}.

Remarks

The culling will discard any triangle which is classified as one of the specified classification value.

The default value is eClassify_Back|eClassify_Coplanar.
