Method Detail

getRayFromCoordinates

void getRayFromCoordinates(double x,
                           double y,
                           Ray ray)

This method generates a ray that has its origin in the cameras origin and will go through the given pixel in the image plane.

Parameters:

x - Represents the relative x postion of the top left corner of the pixel. It ranges from -1 to +1.

y - Represents the relative y postion of the top left corner of the pixel. It ranges from -1 to +1.

ray - The generated ray is stored in this parameter.
