Material for Streamline
Panels for matrial setting is shown in property panel by clicking material icon.
Material settings for material determine width and color, or other several optional settings.
LineProperty
Line width and whether to use dissolve.
Dissolve
Like other materials, semi-transparent object is drawn stocastically pixel-by-pixel.
Combining this effect with ensemble-averaged rendering, stocastic transparency method can be used.
Material
Material setting determines base color and alpha. Streamline can have multiple material settings, at lease in GUI. However, usage of multiple material is not implemented yet. Only Material.0 is valid.
Name
The name is just a tag for users and has no effect. Since valid material is Material.0 only, it is meaningless for current.
Emit
Base color. Streamline is not affected by lighting, and only emission color is defined.
Alpha factor
This value is multiplied to the alpha determined by colorcurve. Selection for alpha blending or additinal blending.
Streamline Shader
Basic shader is uses classical line drawing method. This method is not good for wide line. Polygon line shader draws lines as continuos elonged polygons.
Mapping
When using polygon line shader, a texture can be applied on the curve. This comboobox select the way for mapping. When streamline UV is used, U value given by the stream data is used. When segment UV is used, U [0-1] is mapped on each line between every vertcices.
A default spiral streamline shown when data is undefined U increases 0.1 for every vertices. Thus, when a triangular texture is used, following patterns are shown on the streams.
Streamlin UV, Segment UV
A triangle texture used
Textuere
Texture path for polygon line shader. Optional settings for sequential images and way of interpolation etc. are similar to that for other type of objects.
Colorcurve
Settings for color curve mapped on U space.
Repeat
Usualy, UV coordinated is limited in range [0-1]. However, using U coordinate like time of streamline, its range would not be limited to that range. This option determines wheter to repeat colorcurve outside of the range.
For making colorcurve animation along the stream
Texture Space Modifier can be used to make animation since it can translate UV space.
The tranformation is applyed to UV space that is generated by the streamline data. UV space used for Segment UV mapping woule not be affected. (Thus, the shape of line with small triangles shown above would not be changed).
Option
The meanings of options are similar to that of other types of object.
