Member Function Documentation

void _sanitizeMode (   )  [inline, protected, inherited]
 

Definition at line 32 of file FrameBuffer.h.

void clearColor (  const Color3f &   )  [virtual, inherited]
 

Sets all pixels to given color

= new color

Reimplemented from FrameBuffer.

Definition at line 249 of file FrameBufferGL.cc.

Color3f getColor (  unsigned  ,
unsigned 
)  const [virtual, inherited]
 

Returns the pixel's color.

This method is slow due to manipulation with OpenGL matrices. Use another frame-buffer for this task!

= pixel x position, 0 = left = pixel y position, 0 = bottom = color of the pixel

Reimplemented from FrameBuffer.

Definition at line 239 of file FrameBufferGL.cc.

virtual unsigned getHeight (   )  const [inline, virtual, inherited]
 

Definition at line 81 of file FrameBuffer.h.

Referenced by RTRender::_render().

int getID (  void   )  const [inline]
 

Definition at line 45 of file FrameBufferGLUT.h.

virtual unsigned getWidth (   )  const [inline, virtual, inherited]
 

Manipulation with frame-buffer's width and height (in pixels)

Definition at line 80 of file FrameBuffer.h.

Referenced by RTRender::_render().

void setColor (  const Camera &  ,
unsigned  ,
unsigned  ,
const Color3f & 
)  [virtual, inherited]
 

Reimplemented from FrameBuffer.

Definition at line 59 of file FrameBufferGL.cc.

void setColor (  const Camera &  ,
unsigned  ,
unsigned  ,
float  ,
const Color3f & 
)  [virtual, inherited]
 

Sets the pixel's color.

This method is slow due to manipulation with OpenGL matrices. Use another frame-buffer for this task!

= camera that made the snapshot = pixel x position, 0 = left = pixel y position, 0 = bottom = "depth" of pixel = new color of the pixel

Reimplemented from FrameBuffer.

void setColors (  const Camera &  ,
unsigned  ,
unsigned  ,
const   Color3f[],
unsigned 
)  [virtual, inherited]
 

Reimplemented from FrameBuffer.

Definition at line 126 of file FrameBufferGL.cc.

void setColors (  const Camera &  ,
unsigned  ,
unsigned  ,
float  ,
const   Color3f[],
unsigned 
)  [virtual, inherited]
 

Sets color of many pixels. Setting color pixel by pixel is usually too slow. We can therefore write more pixels at once. Pixels are written by lines starting at given pixel.

= camera that made the snapshot = position x of the first pixel, 0 = left = position y of the first pixel, 0 = bottom = "depth" of pixel = array of new pixel colors = number of pixels

Reimplemented from FrameBuffer.

Definition at line 115 of file FrameBufferGL.cc.

void setHeight (  unsigned   )  [virtual, inherited]
 

Reimplemented from FrameBuffer.

Definition at line 14 of file FrameBufferGL.cc.

References FrameBuffer::setHeight().

void setWidth (  unsigned   )  [virtual, inherited]
 

Manipulation with frame-buffer's width and height (in pixels)

Reimplemented from FrameBuffer.

Definition at line 6 of file FrameBufferGL.cc.

References FrameBuffer::setWidth().

void showContent (   )  [virtual]
 

This method should be called after all pixels have been colorized by the setPixel() method in order to show the picture on screen

Reimplemented from FrameBufferGL.

Definition at line 71 of file FrameBufferGLUT.cc.

References FrameBuffer::_fbMode, and FrameBuffer::FB_DOUBLE.
