- * parameters = {
- *
- * size: , // size of the text
- * height: , // thickness to extrude text
- * curveSegments: , // number of points on the curves
- * steps: , // number of points for z-side extrusions / used for subdividing segements of extrude spline too
- * amount: , // Amount
- *
- * bevelEnabled: , // turn on bevel
- * bevelThickness: , // how deep into text bevel goes
- * bevelSize: , // how far from text outline is bevel
- * bevelSegments: , // number of bevel layers
- *
- * extrudePath: // 3d spline path to extrude shape along. (creates Frames if .frames aren't defined)
- * frames: // containing arrays of tangents, normals, binormals
