Scenekit how to bend an object

Question

I am new to 3D.

I have a direct stick object, which is an SCNBox, and at some point I want to bend it (with animation). Is there any way to achieve this? Or do I need to use several objects to simulate an SCNBox first, and then move and rotate these objects to simulate a bend?

Answer 1

SCNBoxhas a property heightSegmentCountthat can be used to create more vertices.

SCNShaderModifierEntryPointGeometry:

float offset = _geometry.color.x * (sin(1.2 * u_time + (_geometry.position.x + _geometry.position.z) * 4.0) + 0.5) * 0.02;
_geometry.position.x += offset;
_geometry.color.xyz = vec3(1.0);

(SCNGeometrySourceSemanticColor, ), reset 1.0, .
