Having another go at my Russian adventurer, this morning. I am working
smarter, this time, thanks to Khermardi. The total figure is ont eh bottom layer, at 0.4
opacity, and serves as a guide.
Needed to see where the left arm sits:
All three layers of the figure superimposed:
Did one last little adjustment to the upper left leg... Done!

Bard Moment of the Day:
A Catmull-Rom curve is a type of parametric spline curve that is often used in computer graphics to smooth out the movement of objects. It is a piecewise cubic curve, meaning that it is made up of multiple cubic polynomial segments that are joined together at their endpoints. The smoothness of the curve is controlled by a parameter called the tension, which can be adjusted to create a tighter or looser fit to the control points.
Here are some of the key properties of Catmull-Rom curves:
* They are interpolating, which means that they pass through all of the control points.
* They are C1 continuous, which means that they have continuous first derivatives at the joints between the segments. This ensures that the object's velocity changes smoothly as it moves along the curve.
* They can be used to create a variety of different shapes, depending on the placement of the control points and the value of the tension parameter.
Catmull-Rom curves are commonly used in animation to create smooth movements for characters and objects. They can also be used in other applications, such as path planning and modeling.
Here are some of the benefits of using Catmull-Rom curves:
* They are relatively easy to implement.
* They produce smooth and natural-looking movements.
* They can be used to create a variety of different shapes.
Here are some of the drawbacks of using Catmull-Rom curves:
* They can be computationally expensive to evaluate, especially for complex curves.
* They can sometimes produce overshoots or undershoots, which can make the animation look unnatural.
Overall, Catmull-Rom curves are a powerful tool for creating smooth and natural-looking movements in computer graphics. They are relatively easy to use and can be used to create a variety of different shapes. However, it is important to be aware of the potential drawbacks of using Catmull-Rom curves, such as the computational cost and the possibility of overshoots or undershoots.
I hope this explanation helps! Let me know if you have any other questions.
