Method Summary | |
---|---|
double[] | getColor(boolean linear) |
void | getLight(double x, double y, double z, double[] L)
Computes the light vector in (x, y)
|
double[][][] | getLightMap(double x, double y, double dx, double dy, int width, int height, double[][][] z)
Returns a light map, starting in (x, y) with dx, dy increments, a given
width and height, and z elevations stored in the fourth component on the
N array.
|
double[][] | getLightRow(double x, double y, double dx, int width, double[][] z, double[][] lightRow)
Returns a row of the light map, starting at (x, y) with dx
increments, a given width, and z elevations stored in the
fourth component on the N array.
|
boolean | isConstant() |
void | setColor(Color color)
Sets the light color to a new value |
Parameters: linear if true the color is returned in the Linear sRGB colorspace otherwise the color is in the gamma corrected sRGB color space.
Returns: the light's color
Parameters: x x-axis coordinate where the light should be computed y y-axis coordinate where the light should be computed z z-axis coordinate where the light should be computed L array of length 3 where the result is stored
Parameters: x x-axis coordinate where the light should be computed y y-axis coordinate where the light should be computed dx delta x for computing light vectors in user space dy delta y for computing light vectors in user space width number of samples to compute on the x axis height number of samples to compute on the y axis z array containing the z elevation for all the points
Returns: an array of height rows, width columns where each element is an array of three components representing the x, y and z components of the light vector.
Parameters: x x-axis coordinate where the light should be computed y y-axis coordinate where the light should be computed dx delta x for computing light vectors in user space width number of samples to compute on the x axis z array containing the z elevation for all the points lightRow array to store the light info to, if null it will be allocated for you and returned.
Returns: an array width columns where each element is an array of three components representing the x, y and z components of the light vector.
Returns: true if the light is constant over the whole surface
