Modificador Envelopar

The Shrinkwrap modifier allows a Grease Pencil object to «shrink» to the surface of another object. It moves each point of the object being modified to the closest position on the surface of the given mesh.

The Shrinkwrap modifier in Nearest Surface Point mode.

Wrap Method

This selector specifies the method to be used to determine the nearest point on the target’s surface for each point of the modified object. Some options will add some extra, specific controls to the panel. See Wrap Methods for an explanation of each method.

Snap Mode

Most modes support an additional setting to control how the point is moved to the target point selected by the methods described above. Some of the choices only differ if Offset is not zero.

On Surface

The point is always moved. The offset is applied along the projection line connecting the original point and selected target point towards the original position.

Lado interno

The point is not moved if it is already inside the target. Offset shrinks the allowed volume towards the inside along the projection line.

Lado externo

The point is not moved if it is already outside the target. Offset expands the exclusion volume towards the outside along the projection line.

Outside Surface

Like On Surface, but the offset is always applied towards the outside of the target.

Above Surface

Like On Surface, but the offset is applied along the smooth normal of the target.

Nota

The Inside and Outside options can be used for very crude collision detection. The inside vs outside determination is done based on the target normal and is not always stable near 90 degree and sharper angles in the target mesh.

Target

Alvo, a malha para envelopar ao redor.

Deslocamento

The distance that must be kept from the calculated target position.

Smooth Factor

Amount of smoothing to apply.

Repetir

The number of time to apply smoothing.

Pontos mais próximos da superfície

This will select the nearest point over the surface of the shrunk target.

Project mode.

Isso irá projetar vértices ao longo do eixo escolhido até que ele toca o alvo do envelopamento. Vértices que nunca tocam o alvo de envelopamento são deixados na sua posição original.

Limit

This is a distance limit between original point and surface. If the distance is larger than this limit point would not be projected onto the surface.

Subdivision Levels

This applies a (temporary) Catmull-Clark subdivision to the modified object’s geometry, before computing the wrap.

Eixos

Along which local axis of the modified object the projection is done. These options can be combined with each other, yielding a «median axis» of projection. If none are selected, the normal direction is used.

Negative/Positive

This allows you to select the allowed direction(s) of the shrink along the selected axis. If both options are enabled, both ways are evaluated and the closest hit is selected.

Face Cull

Allows you to prevent any projection over the «front side» (respectively the «back side») of the target’s faces. The «side» of a face is determined by its normal (front being the side «from where» the normal «originates»).

Invert Cull

If Cull Faces is enabled, and Negative direction along axis is allowed, this option can be used to invert the Front or Back cull choice for the Negative direction. This is useful when projecting in both directions.

Alvo auxiliar

Um objeto adicional pra projetar sobre.

Vértices mais próximos

Isso ira encaixar vértices para o vértice mais próximo do alvo envelopado. Não adiciona opções extras.

This method doesn’t support the Snap Mode setting.

Target Normal Project

This mode is similar to Nearest Surface Point, but produces a much smoother projection in return for being significantly slower.

Instead of finding the closest point, it searches for the nearest point that has its interpolated smooth normal pointing towards or away from the original point position. Non-manifold boundary edges are specially handled as infinitely thin cylinders that emit normals in all perpendicular directions. Ignores flat shading and auto smooth settings.
