Creating panoramic images in real-time is an expensive operation for mobile devices. Mapping of individual pixels into the panoramic image is the main focus of this paper, since it is one of the most time consuming parts. The pixel-mapping process is transferred from the Central Processing Unit (CPU) to the Graphics Processing Unit (GPU). The independence of pixels being projected allows OpenGL shaders to perform this operation very efficiently. We propose a shader-based mapping approach and confront it with an existing solution. The application is implemented for Android phones and works fluently on current generation devices.
