Function Documentation

void glutSetupVideoResizing (  void   ) 
 

Undocumented, unimplemented.

This function is undocumented. This function is unimplemeneted (presently).

glutVideoResizeGet(), glutSetupVideoResizing(), glutStopVideoResizing(), glutVideoResize(), glutVideoPan()

void glutStopVideoResizing (  void   ) 
 

Undocumented, unimplemented.

This function is undocumented. This function is unimplemeneted (presently).

glutVideoResizeGet(), glutSetupVideoResizing(), glutStopVideoResizing(), glutVideoResize(), glutVideoPan()

void glutVideoPan (  int  x,
int  y,
int  w,
int  h
) 
 

Undocumented, unimplemented.

Parameters:
x A horizontal position.
y A vertical position.
w A width.
h A height.
This function is undocumented. This function is unimplemeneted (presently).

Appears to be for moving the video display about (panning) in a much larger graphic area than will fit on the screen at current resolution.

void glutVideoResize (  int  x,
int  y,
int  w,
int  h
) 
 

Undocumented, unimplemented.

Parameters:
x A horizontal position.
y A vertical position.
w A width.
h A height.
This function is undocumented. This function is unimplemeneted (presently).

This function appears to allow setting the video display rectangle to a sub-rectangle of the hardware buffer. x and y are apparently the upper left corner, and w and h are the width and height of the rectangle.

It is not clear what should be done if the values are invalid (negative x, for example).

int glutVideoResizeGet (  GLenum  eWhat  ) 
 

Undocumented, unimplemented.

Parameters:
eWhat An enumerated tag.
This function is undocumented. This function is unimplemeneted (presently).

From GLUT 3.7's implementation, the following is a list of symbols that GLUT 3.7 supported. These are not necessarily defined in OpenGLUT at this time, nor is support presently available for them:

  • GLUT_VIDEO_RESIZE_POSSIBLE (feature presence)
  • GLUT_VIDEO_RESIZE_IN_USE
  • GLUT_VIDEO_RESIZE_X_DELTA
  • GLUT_VIDEO_RESIZE_Y_DELTA
  • GLUT_VIDEO_RESIZE_WIDTH_DELTA
  • GLUT_VIDEORESIZE_HEIGHT_DELTA
  • GLUT_VIDEO_REISZE_X
  • GLUT_VIDEO_RESIZE_Y
  • GLUT_VIDEO_RESIZE_WIDTH
  • GLUT_VIDEO_RESIZE_HEIGHT

A -1 should be returned for unimplemented features, and a warning printed.
