🟠 Generate Common Shape Point Cloud

Function Description

This operator does not require input data but generates a standard geometric shape point cloud according to user-specified parameters. All generated shapes are centered at the coordinate system origin [0,0,0]. Generatable shapes include rectangle, parallelogram, isosceles trapezoid, circle, concentric circle, semicircle, and concentric semicircle.

Usage Scenarios

When there is no real model file available, quickly generate a standard shape point cloud as a reference model, which can be used for scene construction or algorithm workflow testing.

Input Output

Input

None

Output

Generated point cloud: Geometric shape point cloud generated according to parameters.

Parameter Description

Generated Template Type

Parameter Description

Select the geometric shape to be generated, options include: rectangle, parallelogram, isosceles trapezoid, circle, concentric circle, semicircle, concentric semicircle.

Parameter Adjustment

Rectangle: length, width

Parallelogram: length, height, acute angle

Isosceles trapezoid: upper base, lower base, height

Circle: radius

Concentric circle: concentric circle radius, concentric circle outer diameter

Semicircle: radius

Concentric semicircle: concentric circle radius, concentric circle outer diameter

Parameter Range

Value range [0,1000], except for acute angle units in degrees (°), all other parameter units are mm

Planar

Parameter Description

Controls whether to generate a 2D planar figure or a 3D solid figure.

Parameter Adjustment

  • Enabled (default): Generate a planar shape where all points have Z coordinate of 0.

  • Disabled: Extrude the 2D shape along the Z-axis to generate a 3D solid with specified "Model Vertical Height", requiring configuration of model vertical height.

Parameter Range

[1,1000000], Default value: 10, Unit: mm

Point Distance

Parameter Description

Controls the density of generated point cloud, i.e., the distance between points.

Parameter Adjustment

  • Decrease this value: Generated point cloud is denser and smoother, but data volume and computation time increase.

  • Increase this value: Generated point cloud is sparser with smaller data volume, but shape details may be lost.

Parameter Range

[0,200], Default value: 0.1, Unit: mm

Enable Fill

Parameter Description

Controls whether to generate solid surfaces or only contour lines.

Parameter Adjustment

Enabled (default): Generate surface points of the shape. For 3D objects, will fill both top and bottom surfaces.

Disabled (False): Only generate edges or wireframes of the shape. For example, for a circle, only generate points on the circumference.
