Detailed Description

An animation channel that issues a matrix each frame, read from a table such as might have been read from an egg file.

The table actually consists of nine sub-tables, each representing one component of the transform: scale, rotate, translate.

void AnimChannelMatrixXfmTable::clear_all_tables ( )

Removes all the tables from the channel, and resets it to its initial state.

void AnimChannelMatrixXfmTable::set_table ( char  table_id,
const CPTA_stdfloat table 
)

Assigns the indicated table.

table_id is one of 'i', 'j', 'k', for scale, 'a', 'b', 'c' for shear, 'h', 'p', 'r', for rotation, and 'x', 'y', 'z', for translation. The new table must have either zero, one, or get_num_frames() frames.
