Featuring an intuitive multi-touch interface, several deformation brushes, the ability to import/export OBJ files, and many other awesome features, now thanks to forger you can sketch out ideas anywhere you go.
Simple 3D Navigation
forger makes 3D navigation incredibly easy with its intuitive, well thought, multi-touch gestures. Orbiting, panning and zooming has never been easier!
Save your scenes to the internal scene format and use the popular OBJ file format to import or export new models or base meshes.
With 9 brushes to choose from; standard, clay, flatten, move, smooth, pinch, inflate, layer and mask. You will always find the one you need for the right task, each brush has an alternate function that does even more!
Partial Mesh Visibility
Hiding parts of the model you are working on will help you focus on your sculpture, and getting to hard to reach areas.
Control the areas your Brushes can affect by masking them. Masking will make sculpting in delicate areas easier.
Work on different models at the same time, and jump back and forth between them with ease.
