Function Documentation

INLINE_LINMATH FLOATNAME (  LVecBase2   ) 
 

Returns the indicated row of the matrix as a two-component vector, ignoring the last column.

This assumes the matrix is an affine transform.

Definition at line 266 of file lmatrix3_src.I.

INLINE_LINMATH FLOATNAME (  LVecBase3   ) 
 

Returns the indicated row of the matrix as a three-component vector.

This is a fully general operation.

Definition at line 229 of file lmatrix3_src.I.

References FLOATNAME, and int().

INLINE_LINMATH const FLOATNAME (  LMatrix3   ) 
 

Sets each element of the matrix to the indicated fill_value.

This function definition must appear first, since some inline functions below take advantage of it.
