spline test

 

With this node you can perform various tests against splines by using the particle position.

 

 

[Inputs]

 

#Particle Stream - This pin requires a particle stream to be connected. Connection is not required if Input (Position) pin is connected.

 

Enabled - Enable or disable node evaluation.

 

Shapess by RegEx - You can use regex (regular expressions) to select 3ds max shapes in the scene. This is a very powerful tool to automatize the process.

 

Shapes - List of shapes that you want to use. Double click on shape name to remove it from the list or use Remove button. You can select multiple shapes.

 

Animated Shapes/Splines - Enable this option if splines are animated in any way. Keeping this option disabled results in faster computations.

 

Samples - In order to achieve faster calculations each spline is pre-sampled with user defined number of samples. Keep this number high if spline has many sharp curves as this will result is smoother and more accurate results.

 

 

[Outputs]

 

Particle Stream - Generated particle stream.

 

Position ??? Closest position on spline.

 

Tangent ??? Spline tangent at position.

 

Curvature ??? Spline curvature at position.
