It is either the projection matrix, -modelview matrix, -or the texture matrix. -.SH EXAMPLES -If the current matrix is $C$, and the coordinates -to be transformed are, $v ~=~ (v[0], v[1], v[2], v[3])$. -Then the current transformation is $C ~times~ v$, or -.sp -.ce -.EQ -down 130 -{{ left ( matrix { - ccol { c[0] above c[1] above c[2] above c[3] } - ccol { c[4] above c[5] above c[6] above c[7] } - ccol { c[8] above c[9] above c[10] above c[11] } - ccol { c[12]~ above c[13]~ above c[14]~ above c[15]~ } -} right ) } ~~ times ~~ -{left ( matrix { -ccol { v[0]~ above v[1]~ above v[2]~ above v[3]~ } -} right )} } -.EN -.sp -.P -Calling _cmnd with an argument of $_eqnparam1 ~=~ m[0], m[1], ..., m[15]$ -replaces the current transformation with $(C ~times~ M) ~times~ v$, -or -.sp -.ce -.EQ -down 130 -{{ left ( matrix { - ccol { c[0] above c[1] above c[2] above c[3] } - ccol { c[4] above c[5] above c[6] above c[7] } - ccol { c[8] above c[9] above c[10] above c[11] } - ccol { c[12]~ above c[13]~ above c[14]~ above c[15]~ } -} right ) } ~~ times ~~ -{ left ( matrix { - ccol { m[0] above m[1] above m[2] above m[3] } - ccol { m[4] above m[5] above m[6] above m[7] } - ccol { m[8] above m[9] above m[10] above m[11] } - ccol { m[12]~ above m[13]~ above m[14]~ above m[15]~ } -} right ) } ~~ times ~~ -{left ( matrix { -ccol { v[0]~ above v[1]~ above v[2]~ above v[3]~ } -} right )} } -.EN -.sp -.P -Where '$times$' denotes matrix multiplication, and -$v$ is represented as a $4 ~times~ 1$ matrix. -.br -.SH NOTES -While the elements of the matrix may be specified with -single or double precision, the GL may store or operate on these -values in less than single precision. -.P -In many computer languages $4 ~times~ 4$ arrays are represented -in row-major order. The transformations just described -represent these matrices in column-major order. -The order of the multiplication is important. For example, if the current -transformation is a rotation, and _cmnd is called with a translation matrix, -the translation is done directly on the coordinates to be transformed, -while the rotation is done on the results of that translation. -.SH ERRORS -_const(INVALID_OPERATION) is generated if _cmnd -is executed between the execution of _cmnd(Begin) -and the corresponding execution of _cmnd(End). -.SH ASSOCIATED GETS -_cmnd(Get) with argument _const(MATRIX_MODE) -.br -_cmnd(Get) with argument _const(COLOR_MATRIX) -.br -_cmnd(Get) with argument _const(MODELVIEW_MATRIX) -.br -_cmnd(Get) with argument _const(PROJECTION_MATRIX) -.br -_cmnd(Get) with argument _const(TEXTURE_MATRIX) -.SH SEE ALSO -_cmnd(LoadIdentity), -_cmnd(LoadMatrix), -_cmnd(MatrixMode), -_cmnd(PushMatrix) - |
