Beispiel #1

Datei: SMAA.cpp Projekt: ChristophPacher/Cinder

void SMAA::apply( gl::FboRef destination, gl::FboRef source )
{
	gl::ScopedFramebuffer fbo( destination );

	gl::setMatricesWindow( destination->getSize() );

	// Make sure our source is linearly interpolated.
	GLenum minFilter = source->getFormat().getColorTextureFormat().getMinFilter();
	GLenum magFilter = source->getFormat().getColorTextureFormat().getMagFilter();
	bool filterChanged = ( minFilter != GL_LINEAR || magFilter != GL_LINEAR );

	}

	// Perform SMAA anti-aliasing.
	gl::clear( ColorA( 0, 0, 0, 0 ) );
	draw( source->getColorTexture(), destination->getBounds() );

	// Restore texture parameters.
	if( filterChanged ) {
