mtSplineSample


mtSplineSample lets you resample the input spline to add Uniform, Adaptive and Distance point distribution modes.

This provides even, controllable points on the spline data, making it easier to work with along the design chain.

The original spline on the left has very few, unevenly distributed points. An identical spline has been placed as a child of a mtSplineSample on the right. This has been resampled using 150 points in the Uniform mode. The result is a smooth, higher-quality spline.


You have three options: Uniform, Natural and Distance.

The default setting, the Method is Uniform, distributing a uniform amount of points per segment.

An INSYDIUM logo spline is on the left. On the right, a duplicate spline has been made a child of a mtSplineSample, using the Uniform Method.

Resample can be increased to give you a higher point count per segment.

This parameter is not available in the Distance setting.

Uniform Method with a Resample value of 15 on the left and 100 on the right.

Smooths splines on corners, by using the average point on the segment, between neighboring points.

Natural allocates more points where there is curvature than on straight lines of the segments.

mtSplineSample_natural_120points.PNG

An INSYDIUM logo spline is on the left. On the right, a duplicate spline has been made a child of a mtSplineSample, using the Natural Method.

Resample can be increased to give you a higher point count per segment.

This parameter is not available in the Distance setting.

mtSplineSample999NaturalResample.jpg

Natural Method, with a Resample setting of 35 points per segment on the left and 150 on the right.

Smooths splines on corners, by using the average point on the segment, between neighboring points.

Distance gives you control over the number of points you require in a set distance.

mtSplineSample_Distance_2cm.PNG

An INSYDIUM logo spline is on the left. On the right, a duplicate spline has been made a child of a mtSplineSample, using the Distance Method.

Only available in the Distance setting, this sets how far apart each point is.

mtSplineSample999DistanceStepSize.jpg

Distance Method with a Step Size of 15cm on the left and 2cm on the right.

Smooths splines on corners, by using the average point on the segment, between neighboring points.

This is disabled as a default.

Turning it on will join the start and end points, creating a closed spline.

mtSplineSample_closespline_off.PNG

With Close disabled, the start and end points of each segment are not connected.

mtSplineSample_closespline_on.PNG

With Close enabled, the start and end points are connected, creating a closed spline.


The growth settings are for adjusting the start and end points of your spline.

They can be animated for growth effects.

There are two settings: Pre-Sample and Post-Sample.

Allows you to adjust the start and end points based on the original spline data.

Allows you to adjust the start and end points using the new spline data

There are two settings: Per Segment and Per Spline.

This is the default setting, which controls the growth setting of each segment.

If the input spline has multiple segments, each segment will have its own start and end point.

Per-Spline controls the growth setting of each spline and can begin at either end.

The spline will only have one start and end point, even if it contains multiple segments.

This tab allows us to change how splines are displayed in the viewpoint.

This can be turned off, so that only the start and end points are shown.

You can change the color of the displayed selection using the color picker.

Changes the size of the points.

Shows the color gradient between the start and end points.

This allows you to alter the gradient and the colors used.

You can load a preset gradient from here.
