Avogadro::Rendering::DashedLineGeometry

class DashedLineGeometry : public Drawable

The DashedLineGeometry class is used to store sets of dashed lines.

<avogadro/rendering/dashedlinegeometry.h>

Unnamed Group

size_t addDashedLine(const Vector3f &start, const Vector3f &end, const Vector4ub &color, int dashCount)

Add a complete line strip to the object.

Note

All arrays must be the same length, or this function call will fail, returning InvalidIndex.

Parameters:

• vertices – The 3D vertices which will be connected to form the line strip.

• color – Vertex color. If not specified, use the current color() and opacity(). If the 3 component color is set, the current opacity() is used.

• lineWidth – The width of the line strip.

Returns:

The index of the first vertex added by this call.

size_t addDashedLine(const Vector3f &start, const Vector3f &end, const Vector3ub &color, int dashCount)

Parameters:

• vertices – The 3D vertices which will be connected to form the line strip.

• color – Vertex color. If not specified, use the current color() and opacity(). If the 3 component color is set, the current opacity() is used.

• lineWidth – The width of the line strip.

Returns:

The index of the first vertex added by this call.

size_t addDashedLine(const Vector3f &start, const Vector3f &end, int dashCount)

Add a complete line strip to the object.

Note

All arrays must be the same length, or this function call will fail, returning InvalidIndex.

Parameters:

• vertices – The 3D vertices which will be connected to form the line strip.

• color – Vertex color. If not specified, use the current color() and opacity(). If the 3 component color is set, the current opacity() is used.

• lineWidth – The width of the line strip.

Returns:

The index of the first vertex added by this call.

Unnamed Group

inline void setColor(const Vector3ub &c)

The default color of the lines. This is used to set the color of new vertices when no explicit vertex color is specified.

inline Vector3ub color() const

The default color of the lines. This is used to set the color of new vertices when no explicit vertex color is specified.

Unnamed Group

inline void setOpacity(unsigned char opacity_)

The default opacity of the lines. This is used when either no explicit vertex color is specified, or a three component color is used.

inline unsigned char opacity() const

The default opacity of the lines. This is used when either no explicit vertex color is specified, or a three component color is used.

Unnamed Group

inline void setLineWidth(unsigned char lineWidth_)

The line width used for all of the lines.

inline unsigned char lineWidth() const

The line width used for all of the lines.
