gluProject
[New
- Windows 95, OEM Service Release 2]
The gluProject function maps object coordinates
to window coordinates.
int gluProject(
|
GLdouble objx, |
|
|
GLdouble objy, |
|
|
GLdouble objz, |
|
|
const GLdouble modelMatrix[16], |
|
|
const GLdouble projMatrix[16], |
|
|
const GLint viewport[4], |
|
|
GLdouble * winx, |
|
|
GLdouble * winy, |
|
|
GLdouble * winz |
|
|
); |
|
Parameters
objx,
objy, objz
The object
coordinates.
modelMatrix
The current
modelview matrix (as from a glGetDoublev call).
projMatrix
The current
projection matrix (as from a glGetDoublev call).
viewport
The current
viewport (as from a glGetIntegerv call).
winx,
winy, winz
The computed
window coordinates.
Remarks
The gluProject function transforms the
specified object coordinates into window coordinates using modelMatrix, projMatrix,
and viewport. The result is stored in winx, winy, and winz.
A return value of GL_TRUE indicates success, and GL_FALSE indicates failure.
