Photos and snippets

Paint from real photos: cut snippets from them, calm them to the texture's look, and stamp them onto the model.

Cutting

Switch to photos at the top. Drop photos onto the window or use add photos; they are copied into the project (<project>.snippets/). Pick one, then on the photo:

• drag a rectangle for a straight cut,
• click four corners for a skewed one, like a wall seen at an angle; it gets deskewed,
• drag corners to fit, drag inside to move, ⌫ deletes, F fits the photo. Two fingers pan, pinch zooms.

Look

The panel on the right shows the snippet as it will be stamped:

• pixels: its long side. Keep it near the texel density, so it isn't sharper than the rest.
• width: widens what the photo foreshortened, as a wall seen at an angle.
• calm, saturation, brightness: flatter and quieter than the photo, closer to the texture.
• monochrome: only brightness around mid gray; it goes on a relief layer and tints what is below.

The finish crunches snippets like everything else, auto palette included.

Categories

project holds the project's photos. + makes a global category, for snippets every project can use; a snippet taken from one is copied into the project.

Stamping

With the stamp tool (S) the snippets show at the bottom. Click one: it becomes the stamp shape, on a photo layer that takes its colors from the stamps (photo relief for monochrome ones). Place, size and turn it as any stamp. ⌘click fills the surface under the cursor, bounded by hard edges, with it, and it stays on that surface only; tiles repeats it across, rows following so tiles keep their shape. Axis views from the gizmo are ortho, which keeps projected snippets true.
