com.mousebird.maply.Light

public class Light
extends java.lang.Object

The Light provides a simple interface to basic lighting within the toolkit.
You can have up to 8 lights in the current version of the toolkit. Obviously this is all shader implementation with OpenGL ES 2.0, so you can always just bypass this and do what you like. However, the default shaders will look for these lights. The lights are very simple, suitable for the globe, and contain a position, a couple of colors, and a view dependent flag.

public Light()

Method Detail

getPos

public Point3d getPos()

The location of this particular light in display space.
This is a single light's location in display space. Display space for the globe is based on a radius of 1.0.

setPos

public void setPos(Point3d pos)

The location of this particular light in display space.
This is a single light's location in display space. Display space for the globe is based on a radius of 1.0.

isViewDependent

public boolean isViewDependent()

Controls whether the light takes the model matrix into account or not.
If set, this light moves with the model (usually the globe). You'd use this for a real sun position. If not set, the light is static and does not move or rotate.

setViewDependent

public void setViewDependent(boolean viewDependent)

Controls whether the light takes the model matrix into account or not.
If set, this light moves with the model (usually the globe). You'd use this for a real sun position. If not set, the light is static and does not move or rotate.

setAmbient

public void setAmbient(int color)

Ambient color for the light.
This color will always be added to any given pixel. It provides a baseline lighting value.

setAmbient

public void setAmbient(float r,
                       float g,
                       float b,
                       float a)

Ambient color for the light.
This color will always be added to any given pixel. It provides a baseline lighting value.

getAmbient

public float[] getAmbient()

Ambient color for the light.
This color will always be added to any given pixel. It provides a baseline lighting value.

setAmbient

public void setAmbient(float[] ambient)

Ambient color for the light.
This color will always be added to any given pixel. It provides a baseline lighting value.

setDiffuse

public void setDiffuse(int color)

Diffuse light color.
The diffuse color is multiplied by a directional value and so will vary depending on geometry normals.

setDiffuse

public void setDiffuse(float r,
                       float g,
                       float b,
                       float a)

Diffuse light color.
The diffuse color is multiplied by a directional value and so will vary depending on geometry normals.

getDiffuse

public float[] getDiffuse()

Diffuse light color.
The diffuse color is multiplied by a directional value and so will vary depending on geometry normals.

setDiffuse

public void setDiffuse(float[] diffuse)

Diffuse light color.
The diffuse color is multiplied by a directional value and so will vary depending on geometry normals.
