GLRenderClient

This is a lightweight OpenGL rendering library for Android development, dedicated to help Android developers to reduce development costs, forget the technical details of OpenGL, it can be used in the image editing, video editing.

Import

implementation('io.github.jonanorman.android:glrenderclient:0.2.0')

GLRenderMessage renderMessage = GLRenderMessage.obtain();
renderMessage.post(new Runnable() {
@Override
public void run() {
GLLayer layerGroup = new GLLayerGroup();
layerGroup.render(surfaceTexture);
}
});
renderMessage.recycle();

Feature

Feature1：Automatically parse shader parameters

There is no need to call different APIs to set different variables according to the type of parameters

GLShaderLayer shaderLayer = new GLShaderLayer(); 
shaderLayer.setShaderParam("viewSize", width,height);
shaderLayer.setShaderParam("inputTexture", textureId1);
shaderLayer.setShaderParam("inputTexture2", textureId2);
shaderLayer.setShaderParam("position", position);

Feature2: Asynchronously render Android native View

GLViewLayer viewLayer = new GLViewLayer(getApplicationContext());
viewLayer.setBackgroundColor(Color.WHITE);
LayoutInflater layoutInflater = LayoutInflater.from(viewLayer.getContext());
View view = layoutInflater.inflate(R.layout.layout_view_layer, null);
viewLayer.addView(view);
viewLayer.render(surfaceTexture);

Feature3: multi-Layer multi-timeline render

GLLayerGroup rootLayer = new GLLayerGroup();
rootLayer.setDuration(TimeStamp.ofMills(10000));
GLLayerGroup group = new GLLayerGroup();
group.setDuration(TimeStamp.ofMills(5000));
group.setStartTime(TimeStamp.ofMills(5000));
rootLayer.addLayer(group);
rootLayer.render(surfaceTexture);

Feature4: Effect

GLEffectGroup effectGroup = new GLEffectGroup();
GLShaderEffect shaderEffect =new GLShaderEffect();
shaderEffect.setVertexShaderCode(vertexCode);
shaderEffect.setFragmentShaderCode(fragmentCode);
effectGroup.add(shaderEffect);
GLShaderEffect shaderEffect1 =new GLShaderEffect();
shaderEffect1.setStartTime(TimeStamp.ofMills(2000));
shaderEffect1.setDuration(TimeStamp.ofMills(2000));
shaderEffect1.setVertexShaderCode(vertexCode1);
shaderEffect1.setFragmentShaderCode(fragmentCode2);
effectGroup.add(shaderEffect1);
layer.addEffect(effectGroup);
layer.render(surfaceTexture);

Feature5: shader keyframe

KeyframeSet keyframes = KeyframeSet.ofFloat(10000, 500, 1000, 0);
layer.setKeyframes(GLLayer.KEY_FRAMES_WIDTH, keyframes);
keyframes = KeyframeSet.ofFloat(10000, 500, 600, 500);
layer.setKeyframes(GLLayer.KEY_FRAMES_HEIGHT, keyframes);
layer.setKeyframes(shaderKey,  KeyframeSet.ofFloat(10000, 500, 1000, 0));

Feature6: View Effect

Add special effects to Android native View

<com.jonanorman.android.renderclient.view.GLEffectLayout
        android:id="@+id/effectView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <Button
                android:id="@+id/Button"
                android:layout_width="200dp"
                android:layout_height="200dp"
                android:text="click me">

            </Button>

        </FrameLayout>

    </com.jonanorman.android.renderclient.view.GLEffectLayout>

GLEffectLayout effectView = findViewById(R.id.effectView);
effectView.addEffect(new GLWobbleEffect());
effectView.enableRefreshMode();

Feature7: obj render

Feature8: GaussianBlurEffect

GLGaussianBlurEffect gaussianBlurEffect = new GLGaussianBlurEffect();
gaussianBlurEffect.setBlurRadius(radius);
gaussianBlurEffect.setBlurStep(step);
gaussianBlurEffect.setBlurSigma(sigma);

Feature9: OutlineEffect

GLAlphaOutlineEffect outlineEffect = new GLAlphaOutlineEffect();
outlineEffect.setMaxOutlineWidth(maxWidth);
outlineEffect.setIntensity(intensity);
outlineEffect.setOutlineStyle(style);
outlineEffect.setOutlineColor(color);

Feature10: Solve OpenGL intractable diseases

1. Translucent objects are merged with black borders
2. The problem of texture and image upside down
3. The problem of image squashing when rotating
4. Use BlendMode to implement 15 native Xfermodes of Android
5. automatically check the success of each OpenGL command call
6. Program, Shader, Framebuffer caching  to help reduce memory
7. Support bitmaps that are not a power of 2 or a direct multiplication can also mipmap
8. Solve the problem of different screen size and texture ratio, increase GravityMode, ScaleMode
