2D Poisson Equation solver using Openframeworks.

• Poisson & Laplace Equation

• Left image is boundary condition space and right image is steady state space.
• Poisson Equation's solution is steady state of 2d space in this case.
• Differential equation is converted to difference equation for computer calculation.
• Poisson difference equation is extracted from u(x,u) function's Taylor series(simple finite element method).

• OpenFrameworks 0.11.0
• ofxCv
• ofxOpenCv
• XCode 11.1.x
• OSX Mojave

• Iterational Solution Animation using update() method.
• Pseudo Coloring for grayscale.
• Fast solver using FFT(DST).
• Elapsed Time Display for solve.
