Focos vs. Phogy vs. PyQtGraph vs. Python Comparison Chart

Focos brings DSLR-like photography to your iPhone with big aperture and real bokeh effect, which most photographers have always desired. Portrait photo with depth data allows you to focus after shooting like hacker technology. Various diaphragms generate different bokeh spot effects. Professional options simulate the pro lens such as creamy, bilinear, swirl and so on. Creamy is the characteristic of good lens and makes the edge of bokeh spot softer. Bilinear is the shortcoming of some lens but can stoke spot. Swirly lens highlights the center object surrounded by swirly bokeh. With lighting tool, you can check the portrait picture in true 3D space, add lights and adjust color, brightness and so on and so forth. It is more powerful and flexible than portrait lighting which Apple provides.

PyQtGraph is a pure-python graphics and GUI library built on PyQt/PySide and NumPy. It is intended for use in mathematics/scientific/engineering applications. Despite being written entirely in python, the library is very fast due to its heavy leverage of NumPy for number crunching and Qt's GraphicsView framework for fast display. PyQtGraph is distributed under the MIT open-source license. Basic 2D plotting in interactive view boxes. Line and scatter plots. Data can be panned/scaled by mouse. Fast drawing for real-time data display and interaction. Displays most data types (int or float; any bit depth; RGB, RGBA, or luminance). Functions for slicing multidimensional images at arbitrary angles (great for MRI data). Rapid update for video display or real-time interaction. Image display with interactive lookup tables and level control. Mesh rendering with isosurface generation. Interactive viewports rotate/zoom with mouse. Basic 3D scenegraph for easier programming.
