TriMeshImager generates a triangular mesh from a photo, and converts it to a vector image (drawing art).

You can easily experience a digital art that converts to triangle, flower or heart pattern from photo.

As mesh converter, one of the five types - "Grid", "Concentric Circles", "Painting", "Stained Glass", or "Contour" can be selected.

The patches(triangles) and nodes(vertexes of triangle) of triangular mesh are drawn with color decided by user specified method.

Voronoi diagram (polygon with vertices at circumcenter of triangle) can be displayed.
You can get geometric pattern like turtle's shell.

As patch shape, there are triangle, petal, heart, clover and gear.
As node shape, circle, diamond, heart, gear and text can be selected.

The color of inside and edge of patch or node, is decided with specified color, image color, or gradation derived from image intensity.

Moreover, from Ver.3.2, edges of triangle or Voronoi cell can be deformed like wave shape.

From these combination, you can get not only simple triangular mesh but also more complex flower pattern or dot pattern.

Because the original image can be specified as a background image, this app can be also used as a photo decorator.

Nickel and dimes you!

Let me start by saying this is a quality product that functions well. And the only reason for my three star review is because the developer nickel and dimes you for every little feature!

I would be inclined to buy all his other apps, however concerned they will do the same …such as the only output option being a low-quality JPEG -unless you pay to upgrade your output. And other upgrade features.

ALL and ALL, the pay schedule is probably hurting the developer’s bottom line and would be better off charging one price for the app, or one price to upgrade all features.

The developer may want to even consider a package deal for all his apps that appear very well designed! it's really the only affordable way to get such limited apps you may only tinker with once in a while.

I was unable to save initially but no issues now! Thank you for the quick response. Still navigating the multitude of possibilities with this app, but so far I’m extremely impressed!

Amazing Abstract Art Generator!

So many highly complex options to choose from (have no idea how they all work), but just playing around with it, I can generate some fascinating and beautiful abstract art from photos. Just started with TriMeshImager and already very impressed. Highly recommend!
