Field Summary

static float[]	AMBIENT_LIGHT The ambient light is { 0.2f, 0.2f, 0.2f, 0.0f }.
static float[]	DIFFUSE_LIGHT The diffuse light is { 0.95f, 0.95f, 0.95f, 0.0f }.
static float[]	LIGHT0_POSITION The position of light zero is {200.0f, 200.0f, 200.0f, 1.0f}.
static float[]	SPECULAR_LIGHT The specular light is { 0.95f, 0.95f, 0.95f, 0.0f }.

Constructor Summary

Lighting()
Constructs a Lighting object.

Method Summary

void	disableLighting(GL gl) Disables the lighting.
void	enableLightOne(GL gl, float x, float y, float z) Light one is set to the xyz-coordinates given as arguments Light one is a positional light and is intended to be used for specular lighting.

Field Detail

LIGHT0_POSITION

public static final float[] LIGHT0_POSITION

The position of light zero is {200.0f, 200.0f, 200.0f, 1.0f}. If the last element in the array is zero, then the light is directional. If the last element is non-zero, the light is positional.

AMBIENT_LIGHT

public static final float[] AMBIENT_LIGHT

The ambient light is { 0.2f, 0.2f, 0.2f, 0.0f }.

DIFFUSE_LIGHT

public static final float[] DIFFUSE_LIGHT

The diffuse light is { 0.95f, 0.95f, 0.95f, 0.0f }.

SPECULAR_LIGHT

public static final float[] SPECULAR_LIGHT

The specular light is { 0.95f, 0.95f, 0.95f, 0.0f }.

Constructor Detail

Lighting

public Lighting()
