Organized catmull rom spline implementation in Unity.
Spline logic is in its own data structure; Catmull Points (Position, Normal, Tangent) is its own struct.
I cleaned up the code from my Road Generator repository, since that was... best not to mention it.
If you use it anywhere give me a ping on noobstudiosunity @ gmail.com
Spline Class:
CatmullRomPoint { Position, Normal, Tangent }
Constructor()
Update(Transform[] ControlPoints)
Update(Resolution, ClosedLoop)
DrawSpline(Color)
DrawNormals(Length, Color)
DrawTangents(Length, Color)
Evaluate(p0, p1, m0, m1, t)
CalculatePosition(p0, p1, m0, m1, t)
CalculateTangent(p0, p1, m0, m1, t)
NormalFromTangent(Tangent)
if(spline != null)
{
spline.Update(controlPoints);
spline.Update(resolution, closedLoop);
spline.DrawSpline(Color.white);
if(drawNormal)
spline.DrawNormals(normalExtrusion, Color.red);
if(drawTangent)
spline.DrawTangents(tangentExtrusion, Color.cyan);
}
else
{
spline = new CatmullRom(controlPoints, resolution, closedLoop);
}
