Also, I like this shader:
private final String mFragmentShader =
"precision mediump float;\n" +
"varying vec2 vTextureCoord;\n" +
"uniform sampler2D sTexture;\n" +
"void main() {\n" +
"vec2 center = vec2(0.5,0.5);\n" +
"float intensity = 1.0 - distance(vTextureCoord,center);\n" +
" gl_FragColor = texture2D(sTexture, vTextureCoord) *
vec4(1.0, 1.0, 1.0, intensity);\n" +
"}\n";
Be sure to have blending on:
GLES20.glEnable(GL10.GL_BLEND);
GLES20.glBlendFunc(GL10.GL_SRC_ALPHA,
GL10.GL_ONE_MINUS_SRC_ALPHA);
Here's what it looks like:
