Nodegroups

A collection of free to use node groups, created in my videos or elsewhere

Short descriptions

• RayMarching.blend A collection of node groups related to ray marching, includes some SDF's as well.
• catenary_demo.blend A demo file containing a node group to create a catenary curve (like the shape formed by a hanging chain) between two points.
• euler_integration.blend Demo of forward Euler method using simulation nodes, to solve the differential equation $\frac{dy}{dx} = y, y(0) = 1$ numerically (analytic solution is $y = e^x$). It also contains a node group for the Runge-Kutta method.
• lorenz_system.blend Similar to euler_integration.blend, but applied to the Lorenz system.
• paint_strokes.blend Effect to make an image look "painterly" by instancing planes.
