Method and apparatus for animation of an object on a display

An apparatus for animation of an object comprising:

• means for determining a source projection matrix for projecting a source vertex array of a source object from an original space to an ortho-normal space;
• means for determining a destination projection matrix for projecting a destination vertex array of a destination object from an original space to an ortho-normal space;
• means for determining a zero-mean source vertex array of said source vertex array;
• means for determining a zero-mean destination vertex array of said destination vertex array;
• means for transforming said zero-mean source vertex array to a transformed source vertex array using said source projection matrix;
• means for transforming said zero-mean destination vertex array to a transformed destination vertex array using said destination projection matrix;
• means for computing an interim vertex array in said ortho-normal space based on a linear interpolation of said transformed source vertex array and said transformed destination vertex array;
• means for computing an interim projection matrix based on a linear interpolation of said source projection matrix and said destination projection matrix;
• and
• means for transforming said interim vertex array from said ortho-normal space to said original space based on said interim projection matrix.

• transmitting from a transmitter to a receiver a source projection matrix for projecting a source vertex array of a source object from an original space to an ortho-normal space;
• transmitting from said transmitter to said receiver a destination projection matrix for projecting a destination vertex array of a destination object from an original space to an ortho-normal space;
• determining a zero-mean source vertex array of said source vertex array;
• determining a zero-mean destination vertex array of said destination vertex array;
• transforming, in said receiver, said zero-mean source vertex array to a transformed source vertex array using said source projection matrix;
