Detailed Description

An abstract base class for objects that calculate an approximate remap specified by quadrilatrials.

Each quadrilatrial has vertex coordinates and texture coordinates. The texture coordinates specify for each vertex a point on the image to be mapped to that vertex location, where the range 0 to 1 in either direction is the entirity of the image. The vertex locations are the coordinates in the output in pixels. (They are scaled down to fit in the preview).

A MeshManager then converts the faces specifed into a format sutible for the whatever graphics system is being used to draw them.

Member Function Documentation

◆ ClipFace()

void MeshRemapper::ClipFace ( MeshRemapper::Coords * face )

protected

Crop a face to the source image, return true if there is anything left.

SetCrop() must have been called beforehand with up to date information.

Returns: true if anything remains, false if the entire face was removed.

Referenced by TexCoordRemapper::GetNextFaceCoordinates(), and VertexCoordRemapper::GetNextFaceCoordinates().

◆ GetNextFaceCoordinates()

virtual bool MeshRemapper::GetNextFaceCoordinates ( Coords * result )

pure virtual

Get the texture and vertex coordinates for the next face.

The coordinates are ordered [left / right][top / bottom][x coord / y coord].

Returns: false once specified all faces, true otherwise.

Implemented in ChoosyRemapper, LayoutRemapper, TexCoordRemapper, and VertexCoordRemapper.

Referenced by ChoosyRemapper::GetNextFaceCoordinates().

◆ GiveClipFaceResult()

bool MeshRemapper::GiveClipFaceResult ( Coords * result )

protected

Get a face that was produced by ClipFace.

Parameters

result Place to copy the face to. The pointers in result must be valid.

Returns: true if a valid face was returned, false if there are no faces.

◆ SetCrop()

void MeshRemapper::SetCrop ( )

protected

Fill the crop values of the MeshRemapper from the source image.
