Constructor Details

GlobalEffectsGroup

public GlobalEffectsGroup(org.j3d.aviatrix3d.SimpleScene scene)

Create a new instance with the headlight off and controls over whether the code will be used in a static or dynamic environment.

Parameters:

scene - The scene to use for the global effects

Method Details

setLayerId

public void setLayerId(int id)

Set or reset the layer ID to the new ID value.

Specified by:

setLayerId in interface OGLGlobalEffectsHandler

Parameters:

id - A non-negative ID for the layer

setViewMatrix

public void setViewMatrix(javax.vecmath.Matrix4f transform)

Update the view matrix to be this new matrix.

Specified by:

setViewMatrix in interface OGLGlobalEffectsHandler

Parameters:

transform - The new view matrix settings

setBackgroundMatrix

public void setBackgroundMatrix(javax.vecmath.Matrix4f transform)

Set the background rotation matrix this new matrix.

Specified by:

setBackgroundMatrix in interface OGLGlobalEffectsHandler

Parameters:

transform - The new background matrix settings

setFogMatrix

public void setFogMatrix(javax.vecmath.Matrix4f transform)

Set the fog coordinate matrix this new matrix.

Specified by:

setFogMatrix in interface OGLGlobalEffectsHandler

Parameters:

transform - The new fog matrix settings

updateBackgroundTransparency

public void updateBackgroundTransparency(float transparency)

Update the background transparency to this new value. If the value is 1.0, then disable all the background rendering. A value of 0 is completely opaque and a value of 1 is clear.

Specified by:

updateBackgroundTransparency in interface OGLGlobalEffectsHandler

Parameters:

transparency - A value between 0 and 1

updateBackgroundTextures

public void updateBackgroundTextures(org.j3d.aviatrix3d.Texture2D[] textures,
 boolean[] flags)

Update the background textures to this new set.

Specified by:

updateBackgroundTextures in interface OGLGlobalEffectsHandler

Parameters:

textures - The list of textures to use

flags - The list of flags indicating a texture change

updateBackgroundGround

public void updateBackgroundGround(float[] color,
 float[] angles,
 int num)

Update the background ground color sphere to the new values.

Specified by:

updateBackgroundGround in interface OGLGlobalEffectsHandler

Parameters:

color - The color values to use as a flat array

angles - The angles to use at each colour boundary

num - The number of color values to read from the arrays

updateBackgroundSky

public void updateBackgroundSky(float[] color,
 float[] angles,
 int num)

Update the background sky color sphere to the new values.

Specified by:

updateBackgroundSky in interface OGLGlobalEffectsHandler

Parameters:

color - The color values to use as a flat array

angles - The angles to use at each colour boundary

num - The number of color values to read from the arrays

enableFog

public void enableFog(int state)

Specified by:

enableFog in interface OGLGlobalEffectsHandler

Parameters:

state - The fog to use right now

setFogDetails

public void setFogDetails(float visLimit,
 float r,
 float g,
 float b)

r - The red component of the fog color

g - The green component of the fog color

b - The blue component of the fog color

updateNodeBoundsChanges
