Spline Strip Properties

• Path Node Index: Defines where Path Nodes get added, moved or removed. The first node within a path owns the index 0. If you add nodes at the end, then the Path Node Index is increased automatically to provide a simple path generation.

• X, Y and Z: Sets the Path Node’s X, Y and Z-position.

• TC: Sets the Path Node’s TC-position.

• Add Node: Adds a path node at the current Path Node Index with position X, Y, Z and TC.

• Move Node: Moves the current path node to your required X, Y, Z and TC position.

• Remove Node: Removes a path node at the current Path Node Index.

• Interactive Mode: If you have finished the process of setting path nodes then you are able to edit it simpler by mouse. Just drag and drop the shown nodes to a new position. Left Mouse Button: move node in XY. Middle Mouse Button: move node in XZ.

• Interactive Orientation: World, Local, View. Move nodes interactive with world-, local-, or viewpoint- coordinates.

• Node Size: Sets the interactive node’s size.

• Storage: Is used for storing your defined path nodes in a #-separated string. It is possible to edit nodes directly in the Storage Text field.

• Clear Storage: Clears the spline strip object and its storage.

• Use Time Code: Activates Time Code functionality.

• TC Current: Contains the current Time Code of an external Time Code source.

• TC Start: Sets the starting point of your Time Code animation.

• TC Reference: If you are using more than one spline strip then they probably won’t start all at the same Time Code position. But you can change that by a simple time shift with the Help of TC Reference.

• Path Steps: Defines SplineStrip tessellation.

• Use Threshold: You can optimize your spline strip with that option. Path Steps are added at necessary positions only. So the number of Path Steps increases with a decreasing Threshold.

• Threshold: Sets the Threshold for Path Steps generation.

• Path Start: Sets the starting point of the path geometry.

• Path Length: It defines the length of our spline strip object. Feel free to animate that value!

• Path Alignment: Fits the spline strip to Terrain plug-ins in Viz Artist/Engine. (e.g. use Terrain for drawing paths over a mountain). Available options are; Free and Topography.

• Surface Offset: Shifts Path on Y axis.

• Use Surface Normal: If activated then the surface offset is computed via terrain normals.

• Show Path: Shows the Path which you have defined at the beginning. This option is quite helpful when you are editing Path Nodes.

• Shape Type: If you activate the Organic Mode, your spline strip starts to wobble in dependency of the adjusted Organic Amplitude, Organic Speed, and Organic Period’s Length. Available options are; Static and Organic.

• Shape: Defines the shape used for the loft extrusion. Available options are; Line, Circle and Rectangle.

• Shape Width: Sets the shape’s width.

• Shape Height: Sets the shape’s height.

• Shape Tesselation: Defines how many steps are used to draw the required shape.

• Shape Rotation: You are able to move the spline strip shape up to 360 degrees.

• Shape Orientation: When set to Free, shapes are rotated in dependency of the adjusted Shape Rotation value. When set to XZ, YZ or YX, shapes are auto rotated to obtain a constant SplineStrip width in the required aspect. When set to Terrain, shapes are rotated to fit the terrain beneath them.

• Translate Vertices To Terrain: Moves every single vertex to fit the terrain. This mode only makes sense if you are using Line extrusion.

• Flip Normals: Flips spline strip normals.

• Backface Culling: Switch off drawing spline strip’s backside.

• Organic Amplitude: Adjusts the animated diameter reduction from 0% to 100%.

• Organic Speed: Changes speed of organic mode animation. Also negative values are allowed.

• Organic Period’s Length: Sets the diameter reduction function’s period length.

• Termination: Closes our spline strip object at the Beginning, End or at Both sides. Available options are; None, Beginning, End and Both.

• Arrow: Puts an Arrow to the Beginning, End or Both sides. Available options are; None, Beginning, End, Both

• Object Width: Changes arrow width.

• Object Height: Changes arrow height.

• Object Length: Changes arrow length.

• Object Tesselation: Changes arrow tessellation.

• Generate Texture Coordinates: Activate this function if you are using vertex maps on your spline strip.

• Stretch Texture to Path Length: If activated then the map is stretched to the actual path length.

• Draw Mode: Switch between fill- and wire-frame mode. Available options are; Fill and Wire.

• Buffer Geometry: The whole spline strip data is buffered to memory. If you use spline strips with a huge number of vertices then Buffer Geometry is able to improve performance. Activate this mode only if you do not use any kind of animation in your current spline strip.

• Color: Defines path’s and interactive-mode-node’s color. Color is also used if Wire is activated and no maps are applied onto your spline strip object.

• Child Distance: Defines distance between path end and child container.

• Rotate Child: Activates child container rotation.
