cee::vis::MarkupPartFixedSizeArrow

class MarkupPartFixedSizeArrow : public MarkupPart 

A MarkupModel part for drawing an arrow with a constant size independent of the camera settings.

The arrow will have the given size (in pixels) independent on camera position and settings.

The following settings can be specified:

position: The start position of the arrow
direction: The direction of the arrow
color: The color for the arrow in the part
lengthInPixels: The length of the arrow in pixels
numSubDivisions: The resolution of the arrow. A higher number will give a more smooth arrow, but will result in more triangles per arrow and thus (somewhat) decreased performance.

Public Functions

MarkupPartFixedSizeArrow(const Vec3d &position, const Vec3d &direction, double lengthInPixels, const Color3f &color)

Constructs a part with the given settings.

virtual PartType type() const: Returns the type of the part. Always MarkupPart::FIXED_SIZE_ARROW.

virtual BoundingBox boundingBox() const: Returns the current bounding box of the part.

virtual void setPriority(int priority)

Sets render priority of the part.

The render priority determines the order in which parts get rendered. Parts with lower priorities get rendered first. The default priority is 10.

virtual const Mat4d &transformation() const: Returns the current transformation matrix for the part.

virtual void setTransformation(const Mat4d &matrix): Sets the transformation matrix to use for the part.

const Color3f &color() const: Returns the color of the arrow in the part.

void setColor(const Color3f &color): Sets the color to use to draw the arrows in the part.

void setPosition(const Vec3d &pos): Sets the start position of the arrow.

double lengthInPixels() const: Returns the fixed length in pixels of the arrow.

void setLengthInPixels(double length): Sets the length in pixels of the arrow.

unsigned int numberOfSubDivisions() const

Returns the resolution of the arrow.
