Scalisoft Spacedraw

[Rodney]

This app for androids was available for $2.99 but I believe it has reverted to $11.

Of particular interest is that it appears to support splines and patches. (It can reportedly create 2 sided, 3 sided and 4 sided patches)

As it only exports to .OBJ I'm not sure how well that will work but it makes sense that a quad/spline/patch based model exported to .OBJ might import into A:M better than most.

 

I don't have an Android based phone or tablet so can't test this out.

 

There is a free version that limits the size of the model that can be saved.

From their site:

* the free version only saves / exports scenes with up to 1000 vertices, and no history

Could be useful for creating assets for A:M while on the go.

The free version even more so as it would create models with limited vertices.

 

 

Added: Here is the write up on splines/patches from their manual:

 

Spline surfaces are curved surfaces that are defined by spline-networks, constituting their contours. They can be formed by adjusting control points and handles, providing excellent, intuitive control about their shape:

-the surface passes exactly through the control points

-the surface spreads out parallel to the handles from the control points

-the handle’s length determine the curvature at the control points

 

They are composed of two-, three- or four-sided patches (coons patches in the four- and three-sided case), bounded by splines. Also, patches bounded by any combination of splines, straight lines and arcs can be created. The patches consist of many planar four- or three-sided facets.

 

Usual polygon faces and all kinds of patches of varying facet-count can arbitrarily be combined to contiguous surfaces. Any number of patches can meet at a vertex and at an edge, and they may converge there smoothly or angled. Four-sided patches can be assembled among themselves, and with three-sided patches and planar faces with good tangential- or curvature-continuity (for practical purposes).

 

Thus, Spline surfaces are ideally suited to create complex organic objects with smooth surfaces that also have creases and cusps, with varying richness of detail, and arbitrary topology. Patches bounded by straight lines and arcs let you easily and precisely define surfaces for architectural and mechanical applications.

 

Simultaneously moving control-points and rotating and scaling the adjoining handles with the m,r,s-tool, while concurrently changing the view, lets you easily create any surfaces according to your imaginings.

 

Spline surfaces can be created by

- drawing the curve-networks and then “covering” them with a surface,

- extruding cross-sectional curves,

- deriving them from existing polygon meshes, taking into account the normals to determine the curvature and locations of creases and cusps

 

They can arbitrarily be extended by extruding border- or interior edges to new patches.

 

For adding detail, spline surfaces or single patches can be converted to polygon meshes to make their facets editable individually, and parts of polygon meshes can be converted to spline surfaces.

Looks pretty sweet Rodney. Sadly my android phone would die if I even suggested running this on it. If I ever got a Galaxy Note though this would be a cool companion to it, along with Sketchbook Mobile.
