Resample node: Curveu is wrong? June 26, 2019, 1:32 a.m.

Hi,

from what I understand is, that resampling is normalizing the speed of the curve (that means, that the speed will be constant at every point). On a resampled curve primuv() evaluates each point with @ptnum / (@numpt - 1) but this will not be necessarily the position for primuv() on the old (not resampled) curve. The curveu attribute represents the u-value of the old curve. You can compare the values using the xyzdist() function for the resampled/not resampled curve.

Check my attachement. There is a speed comparison between the resampled an the non resampled curve. You can see, that the green sphere is starting slow an is becoming faster, where the blue sphere has constant speed all the time.

Bad Wire Deform Results - Animating a DNA Strand June 19, 2019, 1:55 p.m.

Hi,

in the path: /obj/DNA_Strand_half/DNA/nucleotide -> change primitive type of the tube from primitive to poylgon.
This gives me better results.
Recently I've created an experimental wire deformer by myself, which gives me more control over the falloff curves etc… and the abililty to shift the geometry along the target curve.
If this helps you, you can use it.

flow along curve like in Rhino 3D in Houdini? May 17, 2019, 12:07 a.m.

Ok.

If the first curve has the shape of the geometry will it straighten the geometry?
For example if you have 3/4 torus and a 3/4 circle and as target a straight line, I am expecting, that the result will straight aswell.
