Class RibbonTrailMesh

Represents a straight ribbon-shaped PrimitiveMesh with variable width.

Inheritance
RibbonTrailMesh

Remarks

RibbonTrailMesh represents a straight ribbon-shaped mesh with variable width. The ribbon is composed of a number of flat or cross-shaped sections, each with the same section_length and number of section_segments. A curve is sampled along the total length of the ribbon, meaning that the curve determines the size of the ribbon along its length.

This primitive mesh is usually used for particle trails.

Properties

curve

Determines the size of the ribbon along its length. The size of a particular section segment is obtained by multiplying the baseline size by the value of this curve at the given distance. For values smaller than 0, the faces will be inverted. Should be a unit Curve.

var curve : Curve

Property Value

Curve

Remarks

section_length

The length of a section of the ribbon.

var section_length : float = 0.2

Property Value

float

Remarks

  • void set_section_length(float value)
  • float get_section_length

section_segments

The number of segments in a section. The curve is sampled on each segment to determine its size. Higher values result in a more detailed ribbon at the cost of performance.

var section_segments : int = 3

Property Value

int

Remarks

  • void set_section_segments(int value)
  • int get_section_segments

sections

The total number of sections on the ribbon.

var sections : int = 5

Property Value

int

Remarks

  • void set_sections(int value)
  • int get_sections

shape

Determines the shape of the ribbon.

var shape : int = 1

Property Value

int

Remarks

  • void set_shape(int value)
  • int get_shape

size

The baseline size of the ribbon. The size of a particular section segment is obtained by multiplying this size by the value of the curve at the given distance.

var size : float = 1.0

Property Value

float
