== ColorScale Filter

The ColorScale filter applies a color to the render image. You can use this filter to tint the render according to one particular color without change any material (underwater scene, night scene, fire scene) or to achieve fade-in/fade-out effect.

Features:

*  Allow to set the color to apply. Default is red.
*  Allow to set intensity of the color. Default is 0.7f. Frag shader clamps color intensity between 0 and 1.

== Old Film Effect Filter

Old Film filter simulate the effect of a classic looking film effect.

Features:

*  Allow to set the *filter's color*. Default is sepia (ColorRGBA(112f / 255f, 66f / 255f, 20f / 255f, 1.0f)).
*  Allow to set the *color's density*. Default is 0.7. Shader clamps this value between 0 to 1. The color image gets grayscale when color's density is set to 0.
*  Allow to set the *noise's density*. Default is 0.4. Shader clamps this value between 0 to 1.
*  Allow to set the *scratches' density*. Default is 0.3. Shader clamps this value between 0 to 1.
*  Allow to set the *vignetting's diameter*. Default is 0.9. Shader clamps this value between 0 to 1.4. Vignetting effect is made using two circles. The inner circle represents the region untouched by vignetting. The region between the inner and outer circle represent the area where vignetting starts to take place, which is a gradual fade to black from the inner to outer ring. Any part of the frame outside of the outer ring would be completely black.

[NOTE]
====
I chose to clamp this value inside the frag shader code instead of using java code because I thought this way is faster (better from performace point of view). You can clamp this value using Java code if you want.

== Dissolver Shader

The Dissolve Shader uses a simple grey scale image as an animated mask to hide a material.

The shader incrementally clamps off the colour value, dark to light, and uses that for a masking texture to discard pixels.
It is currently capped for convenience at 255 frames of animation and is only using one colour channel.
In simple terms, in starts by only discarding the darkest parts of the texture map, then the slightly lighter parts, then the slightly lighter again and again until it eventually can't get any lighter (white), at which point the process is complete.

a|image:plugin/dissolver-screen.png[Dissolver screenshot,width="400",height=""]
a|image:plugin/dissolver-maps.png[Mask maps,width="400",height=""]

|===

Starting at the top left we have: simple linear dissolve, organic dissolve and pixel dissolve.
And bottom row: organic growth, texture masking, organic burn.
Mask texture maps on the second image.

The test is oscillating the dissolve amount between 0 and 1. It demonstrates 6 different uses for the shader, all running at the same speed. The top row are straight forward dissolves. The bottom row shows 3 potential applications:

.  Organic Growth (bottom left) over a mesh, this could work both animating rapidly for a fast grow effect, or set to a fixed value e.g. set to 0.5f is "`50% covered in growth`";
.  Texture Masking (bottom middle) , I see this is probably where the most practical applications will come from. The demonstration shows a poorly photoshopped clean street, pieces of garbage are then scattered around dependant on the dissolve amount, this would work best with a fixed value eg set to .75 is "`75% dirty`". Texture Masking could be also be used for:
..  paint damage on a car;
..  lacerations on a character;
..  the blood shot eye effect that creeps in from the sides of the screen when you’ve taken too much damage in a modern FPS.

.  Organic Burn (bottom right) is comprised of 2 cubes, one blue, one orange, both with the same organic dissolve, however the orange one is slightly offset ahead of the blue so it shows first (ie the dissolve amount is always slight advanced).

a|.mTheoryGame
image:plugin/wUfMcN1Uv48.jpg[youtube_wUfMcN1Uv48,width="",height="",link="https://youtu.be/wUfMcN1Uv48"]

|===


=== Usage

The shader requires 2 parameters:

*  a Texture2D texture map to use as the dissolve map; and
*  a Vector2 of internal params params:
**  the first is a float value being the amount of dissolve, a value from 0-1 : 0 being no dissolve, being fully dissolved; and
**  the second value is an int use as an inversion switch, 1 to invert the dissolve/discard, 0 to leave as is.

[NOTE]
====
Dissolver is based on Common/MatDefs/Lighting.j3md. So, all Common/MatDefs/Lighting.j3md features should be available on the dissolver too.
====

[source,java]
----
// Create a material instance using ShaderBlow's Lighting.j3md
final Material mat = new Material(this.assetManager, "ShaderBlow/MatDefs/Dissolve/Lighting.j3md");
mat.setColor("Ambient", ColorRGBA.Blue);
mat.setColor("Diffuse", ColorRGBA.White);
mat.setColor("Specular", ColorRGBA.Black);
mat.setBoolean("UseMaterialColors", true);

this.assetManager.loadTexture("TestTextures/Dissolve/burnMap.png", mat.setTexture("DissolveMap", map)); // Set mask texture map

this.DSParams = new Vector2f(0, 0); // standard dissolver
//this.DSParamsInv = new Vector2f(0, 1); // inverted dissolver
mat.setVector2("DissolveParams", this.DSParams); // Set params

final Box b = new Box(Vector3f.ZERO, 1, 1, 1);
final Geometry geom = new Geometry("Box", b);

== FakeParticleBlow Shader

Effect for fire or engine of a ship. Such an effect is used in the "`Eve Online`" game for ship engines.

Features:

.  GPU animation (now you don’t need simpleUpdate(float tpf) for the shader). Animation is made displacing the texture according to X and/or Y axis.
.  X and/or Y animation direction. No animation is supported also.
.  Animation direction changer. By default the Y axis animation's direction is up-to-down and the X axis animation's direction is right-to-left.
.  Allow to set animation speed.
.  Allow to set mask texture in order to set particle shape.
.  Allow to set particle color.
.  Allow to set fog color. Fog color is applied to the material using for color's alpha value as fog distance factor.

|===


=== Usage

Create a material (by SDK or by code) using link:https://github.com/jMonkeyEngine-Contributions/shaderblowlib/blob/master/ShaderBlow/assets/ShaderBlow/MatDefs/FakeParticleBlow/FakeParticleBlow.j3md[FakeParticleBlow.j3md].
Set material's parameters and set the material to a spatial.

Most of the cases the spatial will be 4 to 10 planes in the same location but rotated on Y axis using different angles for each plane. Something similar to this:

image:plugin/fakeobject.png[fakeobject.png,width="100",height=""]


[IMPORTANT]
====
Remember to set the queue bucket to transparent for the spatial.
====

[source,java]
----
// Create the material
final Material mat = new Material(this.assetManager, "ShaderBlow/MatDefs/FakeParticleBlow/FakeParticleBlow.j3md");

// Create the mask texture to use
final Texture maskTex = this.assetManager.loadTexture("TestTextures/FakeParticleBlow/mask.png");
mat.setTexture("MaskMap", maskTex);

// Create the texture to use for the spatial.
final Texture aniTex = this.assetManager.loadTexture("TestTextures/FakeParticleBlow/particles.png");
aniTex.setWrap(WrapMode.MirroredRepeat); // NOTE: Set WrapMode = MirroredRepeat in order to animate the texture
mat.setTexture("AniTexMap", aniTex); // Set texture

mat.setFloat("TimeSpeed", 2); // Set animation speed

mat.setColor("BaseColor", ColorRGBA.Green.clone()); // Set base color to apply to the texture

// mat.setBoolean("Animation_X", true); // Enable X axis animation
mat.setBoolean("Animation_Y", true); // Enable Y axis animation
mat.setBoolean("Change_Direction", true); // Change direction of the texture animation

mat.getAdditionalRenderState().setFaceCullMode(FaceCullMode.Off); // Allow to see both sides of a face
mat.getAdditionalRenderState().setBlendMode(BlendMode.Additive);

final ColorRGBA fogColor = ColorRGBA.Black.clone();
fogColor.a = 10; // fogColor's alpha value is used to calculate the intensity of the fog (distance to apply fog)
mat.setColor("FogColor", fogColor); // Set fog color to apply to the spatial.

final Quad quad = new Quad(3, 3); // Create an spatial. A plane in this case
final Geometry geom = new Geometry("Particle", quad);
geom.setMaterial(mat); // Assign the material to the spatial
TangentBinormalGenerator.generate(geom);
geom.setQueueBucket(Bucket.Transparent); // Remember to set the queue bucket to transparent for the spatial
----

To get green/yellow/blue fog (not transparency):

[source,java]
----
mat.getAdditionalRenderState().setBlendMode(BlendMode.AlphaAdditive);
final ColorRGBA fogColor = ColorRGBA.Blue.clone();
----

Several planes geometries will be required as there will be AlphaAdditive material.

== Forceshield Shader

Forcefield shader adds shield effect to a spatial.
The spatial will be a sphere most of the cases, but box or oval should be possible to use. Only problem is that it has to be higher-poly because distance is calculated from vertex.

Hits are registred as contact point position using this control and effect animation is based on distance from contact point and time.
Max number of hits displayed is 4.

Features:

*  Allow to set texture of the shield.
*  Allow to set color of the shield.
*  Allow to set minimal visibility (similar to alpha value). Default is 0, that means shield is no displayed, only hit animations.
*  Allow to set effect duration. Default is 0.5s.
*  Allow to set effect size. Default is 1.
*  Allow to enable/disable hit animations.
