How to install Curves in your project?
To add Curves to your project, simply follow the simple steps below :

• It is best to include the Spline and Mathematics packages before installing Curves.
• Open the Packages window and select My Assets from the package scope drop-down menu.
• Select the Curves package from the list of packages. The package information appears in the details panel.
• Click the Install button.

To generate Splines automatically, according to your selection, make sure have selected at least two Transforms in the active scene. Then go to Abthoclo/Tools/Curves/Generate Curves, or use the shortcut Ctrl + Alt + G

A SplineContainer will automatically be generated according to your selected transforms.

Inspector Transforms
Transforms that control the flow of the generated splines. The order of this array determines the flow, while the position, rotation and scale deterime the location of the splines.

Algorithm
Options between random generations, or create splines that follow a static grid.

Spline Count
The number of Splines that are generated.
Note: Shortcut for adjusting the spline Count is holding the key G and mousescroll up/down.

Seed
Sets the seed for the random spline generator.

Gravity
The gravity applied to the spline generator.
Note: Shortcut for adjusting the gravity is hold G and move the mouse vertically.

Is Parallel
Force the generated splines in a parallel.

Orientation of Handles
The direction the generated splines should follow. Automatically is the default.

You can override the orientation of the handles and the strength. You can choose between Auto, Local or Global. Local and Global gives you a few presets of most likely orientations. However, there is the possability to include a custom orientation.


Samples
Curves contains a sample scene for the Generator, it is located at Abthoclo/Curves/Examples/Generator/

To actived the Raycast ability go to Abthoclo/Tools/Curves/Generate Ray Curves, or use the shortcut Ctrl + Alt + R

Once activated you can simple click on any surface to provide the start position of the curve, and again to determine the end position.
Press 'escape' in case of cancelling the raycast generator.

Note: Shortcut for adjusting the spline strength is holding the key C and mousescroll up/down.
Inspector This inspector can be removed, once finished with the Raycast.

Samples
Curves contains a sample scene for Raycast, is is located at Abthoclo/Curves/Examples/Raycast/

To add a VibrationPresets asset, go to Assets/Create/Abthoclo/Feedback/Haptic/Presets

A VibrationPresets will force the presets to be included in the project/build, without a reference, and can be called upon by its name.

Inspector Is Auto Build
Will rebuild with every small changes to the SplineContainer or Modifiers. Disable this to increase performance.

Rebuild
Force a rebuild of the mesh.

Update At Runtime
Automatically update the Mesh Generator at runtime.

Modifiers
List of available modifiers to combine into one mesh. You disable, remove, copy/paste modifiers. This also includes your own custom modifiers. See 'Custom Modifier' below.


Samples
Curves contains a sample scene for curves, it is located at Abthoclo/Curves/Examples/Curves/

To add the Extrude component, go to Abthoclo/Tools/Curves/Mesh Generator/Extrude - Curves

The Extrude modifier will extrude a mesh along the SplineContainer with the parameters provided in the inspector.

Inspector Segments Per Curve
The number of segments per curve.

SHAPE
Select SplineContainer Shape
Select a SplineContainer in the scene or project that you want to use as the shape to extrude, default shape is a circle. NOTE: Curves uses the X and Z for the shape, so make sure the shape is flat.

Clear Shape data
Revert back to the default shape by erasing the custom shape data.

Resolution Shape
The resolution of the extruded shape. A higher number means more details.

Cap Start
Indicates if the start of the mesh are filled.

Cap End
Indicates if the end of the mesh are filled.

Can Solidify
Indicates if the mesh has a thickness.

Thickness
Thickness of the extruded mesh. This is a normalized value."

Inverse Mesh
Inverse the mesh incase of flipped normals.

ROTATION
Start Rotation
Initial rotation of the extrude.

Additional Rotation Type
"Apply additional scaling according to total distance of the spline, or by custom distance."

SCALING
Scale Shape
Adjust the scale of the extrude.

Additional Scaling
Apply additional scaling according to total distance of the spline, or by custom distance.

UV
Calculate Uvs
Include UV0 in the generated mesh.

Calculate Lightmap
Include UV1 - Lightmap in the generated mesh.
Update At Runtime
Automatically update the Mesh Generator at runtime.

Rebuild
Force a rebuild of the mesh.


Samples
Curves contains sample scenes for Extrude, they are located at Abthoclo/Curves/Examples/Extrude/

To add the Position component, go to Abthoclo/Tools/Curves/Mesh Generator/Position - Curves

The Position modifier will place a mesh along the SplineContainer without distorting the mesh reference.

Inspector Mesh
Mesh reference. Default mesh is a cube.

Threshold
The normalized position along the spline(s) you want to place the Mesh.

Transform Options
Offset
Adjust the offset of the mesh according to the Spline Element.
Orientation
Adjust the orientation of the mesh according to the Spline Element.
Scale Mesh
Adjust the scale of the mesh according to the Spline Element.

Update At Runtime
Automatically update the Mesh Generator at runtime.

Rebuild
Force a rebuild of the mesh.


Samples
Curves contains a sample scene for the Position, it is located at Abthoclo/Curves/Examples/Position/

To add the Repeat component, go to Abthoclo/Tools/Curves/Mesh Generator/Repeat - Curves

The Repeat modifier will repeat a mesh along the SplineContainer with distorting the mesh reference.

Inspector Auto + Default Settings Mesh
Mesh reference. Default mesh is a cube.

Spacing
Spacing
Additional space between each instance.
Spacing Type
Spacing type to calculate the space value. You have the option between a constant or relative type.
Transform Options
Offset
Adjust the offset of the mesh according to the Spline Element.
Orientation
Adjust the orientation of the mesh according to the Spline Element.

To convert a SVG file to a Unity SplineContainer, go to Abthoclo/Tools/Curves/Utils/SVG to SplineContainer


A dialog prompt will open up to locate your SVG file.

For best results export your SVG file with a SVG 1.1 profile, with type 'Convert to outline'.


On the generate SplineContainer is a Transform SVG component included to modify however you like. Reminder: Shapes for the Extrude Modifier are using the X and Z axis, so make sure your shape is orientated flat.

Convert
Converts the SplineContainer according to the transfom custom settings.

Convert Automatically
Converts the SplineContainer to a one unit SplineContainer.

Include your own custom modifiers, simple use the template below to start creating your own awesome modifier. This modifier will then automatically be included in the Curves Component.
