Detailed Description

Corresponding to an <Xfm$Anim> entry, this stores a two-dimensional table with up to nine columns, one for each component of a transformation.

This is an older syntax of egg anim table, not often used currently--it's replaced by EggXfmSAnim.


Constructor & Destructor Documentation

EggXfmAnimData ( EggXfmAnimData const  copy)
EggXfmAnimData ( EggXfmSAnim const  convert_from)

Converts the newer-style XfmSAnim table to the older-style XfmAnim table.

EggXfmAnimData ( string  name,
CoordinateSystem  cs 
)

Member Function Documentation

static TypeHandle getClassType ( ) [static]

Reimplemented from EggAnimData.

CoordinateSystem getCoordinateSystem ( )

Returns the coordinate system this table believes it is defined within.

This should always match the coordinate system of the EggData structure that owns it. It is necessary to store it here because the meaning of the h, p, and r columns depends on the coordinate system.

int getNumCols ( )

Returns the number of columns in the table.

This is set according to the "contents" string, which defines the meaning of each column.

int getNumRows ( )

Returns the number of rows in the table.

static string getStandardOrder ( ) [static]

Returns the standard order of matrix component composition.

This is what the order string must be set to in order to use set_value() or add_data() successfully.

getValue ( int  row,
Mat4D  mat 
)

Returns the value of the aggregate row of the table as a matrix.

This is a convenience function that treats the 2-d table as if it were a single table of matrices.

double getValue ( int  row,
int  col 
)

Returns the value at the indicated row.

Row must be in the range 0 <= row < get_num_rows(); col must be in the range 0 <= col < get_num_cols().

bool hasContents ( )
bool hasOrder ( )
EggXfmAnimData operator= ( EggXfmAnimData const  copy)

setOrder ( string  order)
