[SOLVED] How to make screen blend mode?

Pesegato · March 24, 2016, 6:51am

I’d like to have screen blend mode between 2 moving layers… is it possible to have that? Do I have to write a shader that keeps track of the position of the overlapping layer to have it work properly?

I just googled “opengl photoshop blend modes” because I was trying to find an old site that used to list blend mode settings for various photoshop blend modes…but couldn’t find it easily.

However, the first link answers your question I think:

I’ve seen this, but is for 3.0

https://javadoc.jmonkeyengine.org/com/jme3/material/RenderState.BlendMode.html

Is there a published javadoc for 3.1? Would it be possible to have it with gradle and stuff?

And yes, I’m aware that I can see the source on github… but javadoc is more convenient

github.com

jMonkeyEngine/jmonkeyengine/blob/master/jme3-core/src/main/java/com/jme3/material/RenderState.java#L128


     */
    Always
}

/**
 * <code>BlendEquation</code> specifies the blending equation to combine
 * pixels.
 */
public enum BlendEquation {
    /**
     * Sets the blend equation so that the source and destination data are
     * added. (Default) Clamps to [0,1] Useful for things like antialiasing
     * and transparency.
     */
    Add,
    /**
     * Sets the blend equation so that the source and destination data are
     * subtracted (Src - Dest). Clamps to [0,1] Falls back to Add if
     * supportsSubtract is false.
     */
    Subtract,

And by the way, to answer myself:

material.getAdditionalRenderState().setBlendMode(RenderState.BlendMode.Screen);

A -javadoc.jar is published with each of the jars along with a -sources.jar in standard maven repo style. If you mean is it pushed to the web site somewhere then I don’t think so. I guess that happens after the real release.

Depends on the IDE, but on Netbeans at least right click on your project Dependencies on Projects tab. Select “Download sources”. It’ll get sources and JAVADOC.
