Color3f getColor ( unsigned ,

unsigned

) const [virtual]

Returns the pixel's color.
This method is slow due to manipulation with OpenGL matrices. Use another frame-buffer for this task!

void setColor ( const Camera & ,

unsigned ,

const Color3f &

) [virtual]

Sets the pixel's color.

References FrameBuffer::_width.

void setColors ( const Camera & ,

unsigned ,

unsigned ,

float ,

const Color3f[],

unsigned

) [virtual]

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

void showContent ( ) [virtual]

Force to show the frame-buffer content on the screen. This method should be called after setColor() and setColors().
Reimplemented from FrameBuffer.
