Hello,
I am trying to render my whole scene to an FBObject to apply some post processing effects. I looked at FBOMix2DemosES2 and modified it to use only one FBO.
2 problems arose:
1. When using global MSAA I can't control texture sampling MIN and MAG_FILTER.
The following code is executed:
if(numSamples>0) {
fbo.attachColorbuffer(gl, 0, true);
fbo.resetSamplingSink(gl);
fboTexAttachment = fbo.getSamplingSink().getTextureAttachment();
} else {
// fbo0Tex = fbo.attachTexture2D(gl, 0, true);
fboTexAttachment = fbo.attachTexture2D(gl, 0, true, GL.GL_LINEAR, GL.GL_LINEAR, GL.GL_CLAMP_TO_EDGE, GL.GL_CLAMP_TO_EDGE);
}
As you can see, if no MSAA is used, I changed the default attachTexture2D() call to the one which can take MIN and MAG filters. If MSAA is used, fbo.resetSamplingSink(gl) internally calls the following code:
samplingColorSink = createColorTextureAttachment(gl, cb0.getFormat(), width, height,
GL.GL_NEAREST, GL.GL_NEAREST,
GL.GL_CLAMP_TO_EDGE, GL.GL_CLAMP_TO_EDGE);
Is there a simple way to control this without changing FBObject source, or should I file a bug report?
2. Using Graph API Font rendering with local VBAA / MSAA enabled (multi pass) renders to a different FBO and no text can be seen in my FBO. Is there a way to specify which FBO should multi pass font rendering be applied to? If not, should I file another bug report?
