A user-friendly mathematical plotter. Its main purpose is displaying 2D/3D functions, defined in rectangular, polar and cylindrical coordinates, relations between variables, parametric curves/surfaces and vector fields. It is based on SDL and OpenGL
- Fixed interval acos(), which returned an invalid interval. - Fixed nasty bugs in expression evaluation which caused artifacts near function infinite discontinuities. - Really fixed display on 24-bit video modes: horizontal lines and text didn't appear.
- Switched to C++. Many things have been reimplemented and rewritten from scratch. - Improved explicit curves in polar coordinates, written interval version. - Improved 2D parametric curves in rectangular coordinates. - Experimental plot saving to BMP. - ...
- Preliminary RGB and HSV plots. The syntax is the same as parametric plots: (r g b)=(x 1/y cos(x+y)). - Vector plots now include flow lines officially. Click anywhere with the left mouse button (or control-click) to plot the flow line which is passing ...
- Implemented remaining hyperbolic functions (acosh, asinh, tanh, atanh). - Better display of 3D vector fields, with colors like relation plots and "arrows". - Expressions in the form a-(b+c) were displayed as a-b+c, but evaluated correctly. This has ...
- Implemented an approximation for the Gamma function. The graph is quite thick due to interval methods, and there are the usual artifacts near poles, but it should be a good gamma approximation. - Many experiments with flow lines however results are ...
First release, basic plot features.
