ImplicitFunc2d
ABSTRACT
Generates a 2D implicit function mesh based on specified parameters. We use the marching squares algorithm.
REMARK
In general, The granularity is not great and I do not recommend using this function in its current state
PARAMETERS
| x_min | Minimum x-value for the function's domain |
| x_max | Maximum x-value for the function's domain |
| y_min | Minimum y-value for the function's domain |
| y_max | Maximum y-value for the function's domain |
| x_min | Minimum x-value for the function's domain |
| x_max | Maximum x-value for the function's domain |
| y_min | Minimum y-value for the function's domain |
| y_max | Maximum y-value for the function's domain |
| x_step | Step size for the x-coordinate. This dictates the granularity in the x direction. |
| y_step | Step size for the y-coordinate. This dictates the granularity in the y direction. |
| f(x,y) | The function f(x, y) that defines the 2D implicit function. This should a return a scalar. The generated contour is going to be the boundary of the where this function is <= 0. This may be unexpected as in many cases this adds lines along the boundary of the rectangle (even if the function would not actually be approximately zero there). |
| tag | A vector of numbers used as the mesh's tag |
| default | An enum branch specifying to use the default coloring scheme, white stroke with no fill |
| stroke | A 4-vector representing the color of the stroke |
| stroke | A 4-vector representing the color of the stroke |
| fill | A 4-vector representing the color of the fill. Note that this forces an uprank |
RETURN
Generates a 2D mesh representing the specified implicit function over the given domain
