Geometry#

The Geometry class represents atomic geometry objects displayed in the VTK viewer, providing a unified interface for point clouds, orientations, and surface data with associated visualization properties.

Constructor#

Geometry

VTK-based geometry representation for 3D point clouds and meshes.

Core Data Properties#

`Geometry.points`	3D point coordinates of the geometry.
`Geometry.normals`	Normal vectors at each point.
`Geometry.quaternions`	Orientation quaternions for each point.
`Geometry.sampling_rate`
`Geometry.actor`	VTK actor object for rendering.
`Geometry.visible`	Visibility state of the geometry.

Visualization Control#

`Geometry.set_color`([color])	Set uniform color for all points in the geometry.
`Geometry.set_visibility`([visibility])	Set geometry visibility in the scene.
`Geometry.set_appearance`([size, opacity, ...])	Set visual appearance properties of the geometry.
`Geometry.change_representation`([representation])	Change the visual representation mode of the geometry.

Point Coloring#

`Geometry.color_points`(point_ids, color)	Color specific points in the geometry using set_scalars backend.
`Geometry.set_scalars`(scalars, color_lut[, ...])	Set scalar data for coloring points.

Data Manipulation#

`Geometry.swap_data`(points[, normals, faces, ...])	Replace geometry data with new point cloud or mesh data.
`Geometry.merge`(geometries)	Merge multiple geometry objects into a single geometry.

Utility Functions#

`Geometry.get_number_of_points`()	Get total number of points in the geometry.
`Geometry.compute_distance`(query_points[, k])

VolumeGeometry#

The VolumeGeometry class extends Geometry to handle volumetric data with isosurface rendering capabilities for 3D volume visualization.

Constructor#

VolumeGeometry

Geometry class specialized for 3D volume rendering with isosurfaces.

Volume Operations#

`VolumeGeometry.update_isovalue`(upper[, lower])	Update the isovalue for volume surface rendering.
`VolumeGeometry.update_isovalue_quantile`(...)	Update isovalue using quantile-based thresholds.

GeometryTrajectory#

The GeometryTrajectory class handles time-series geometry data, enabling animation and temporal analysis of evolving geometric structures.

Constructor#

GeometryTrajectory

Geometry class for displaying animated trajectory sequences.

Trajectory Control#

`GeometryTrajectory.frames`	Number of frames in the trajectory.
`GeometryTrajectory.display_frame`(frame_idx)	Display specific trajectory frame.
