Volumetric Drawing

Lens Studio's VolumetricLine package allows you to create high-quality 3D tubes by extruding circular cross-sections along a path. Unlike simple 2D lines, these have actual volumetric geometry that responds to lighting, can be capped, and uses spline interpolation for perfect smoothness.

Creating a 3D Line

To define a path, you provide an array of SceneObject points.

const line = this.sceneObject.getComponent("Component.VolumetricLine");

// Define the control points in the room
line.pathPoints = [pointStart, pointMid, pointEnd];

// Configure quality
line.radius = 2.0; // Thickness in cm
line.circleSegments = 16; // Hoop detail
line.interpolationSteps = 10; // Spline smoothness
line.smoothness = 0.5; // Tension

// Color and Material
line.material = myNeonMaterial;
