The PinchZoomModifier3D provides pinch zooming behavior on a 3D SciChart3DSurface within SciChart - High Performance JavaScript 3D Charts
To apply the PinchZoomModifier3D to a SciChart3DSurface and add pinch zoom behavior, use the following code:
const sciChartS3Durface: SciChart3DSurface; sciChart3DSurface.chartModifiers.add(new PinchZoomModifier3D());The speed of zoom can be modified via the {@link PinchZoomModifier3D.mouseWheelSensitivity} property.
