Image Projection

In this section we will cover how to import, adapt and project an image onto the last that we have prepared. The first thing we want to do is import the image we want to project to our last, we do this by drag and drop and choosing picture when prompted by Rhino. We want to use the 1 to 1 option to keep the proportions of the input file. Once we have the image imported we will see it as seen in the picture.

Align and deform the image

Once we have the image imported we want to align it and scale it so that it matches the last as best we can. Be mindful that you do not need to perfectly align this to the last, if the design is very dynamic it may not respect the last at all. Once we have the image align we want to convert the surface to a mesh for later deformation.

Tip

A little note about meshing, we use these parameters for generating a good mesh that can be easily deformed later in the process. In this process we use the _Mesh command

Once we have the image converted to a mesh we will be able to easily use the botcha soft edit B_SoftEditGrips softedit to adjust the image and deform it to match the last as best as we can. Using the soft edit we want to match the outline of the last with some very easy manipulation.

Once the image is properly aligned you want to use the B_ProjectImage projimg to get the image projected onto the last.

Tip

The best results are achieved with the ProjectionDirection=MeshNatural option but you can use the camera alignment to stencil the image onto your last. You can project your image on any number of meshes, to achieve different results and support your design as best as you can.

When you do a projection a texture will be saved in the same folder as your current file, also a material will be created out of this. In our example we did two different projection and the materials look like this:

The result with the projection will look like in the picture.

After we have projected onto the last, one thing that we can do is re-use the same material to apply it to the flattened last so that you will have a de-facto flattening of your image. This can really help with the creation process either for a virtual prototype or a creation of a pattern.
