Hi,
I am creating a magnifying glass in an application Artoolkit. But I am faced with some problems.
A magnifying glass should move in a vertical orientation from top to bottom.
So that when a model associated with a brand is rendered a magnifying glass will follow this model leaving a path from top to bottom.
the code:
recenter_y-=1;
glRasterPos2i (recenter_x, recenter_y);
glPixelZoom ( 2, 2 );
glCopyPixels (recenter_x, recenter_y, 100, 100, GL_COLOR);
glReadBuffer(GL_BACK); //selecção do buffer para a leitura
glDrawBuffer(GL_FRONT); //selecção do buffer para a escrita
glDrawPixels(100, 100, GL_RGB, GL_UNSIGNED_BYTE, checkImage);
glFlush();
Can you help me please?
