[Plugin] SketchyMesh (terrain & shape maker)

[Ineshtine]

SketchyMesh is an easy terrain and shape builder. It is based on the formula z=f(x,y) for a grid where you enter your own ruby formula using x and y. You can download it from http://Raylectron.com it is free with source code but is (c)2012 SoftByte Labs Inc.

Here are some screen shots of the GUI and formulas used...

Thanks, Raylectron. I have not installed, and am math-poor, but looks interesting. And thanks for posting the examples. I hope there will be more from wherever. For me, hidden geometry displayed in the absence of other materials is most revealing and helpful, but I understand not all share my view. Some actually render.

You are welcome

You don't need to know math, really, just modify the ones that comes with the plugin and see what it does. There is an Undo button to easily undo the mesh, so you can change the formula quickly on every turn. You can go the "View" menu and turn on "Hidden Geometry". My examples above have a material to them, but the plugin doesn't do that, it only create a mesh.

Here is one with the Hidden Geometry...

That's very nice that it comes with formulas to sample.
(I figured the materials were added post prod; I meant in your displayed examples.)

Hi!
I know it's been some time since the release but I have problem with mesh generation.

Any formula that I type, for example "x^2", results with a step function mesh, as if values were approximated to integers, not real numbers. Only example formulas work fine.

This is not how a parabola should look like, huh?

Hi, do not use x^2 but instead, use x**2, in Ruby the ^ operator is a binary xor. See the operator list for Ruby...

Ruby - Operators

Ruby supports a rich set of operators, as you'd expect from a modern language. Most operators are actually method calls. For example, a + b is interpreted as a.+(b), where the + method in the object referred to by variable a is called with b as its argument.

Try this formula...

((x-y)**2)/20
