RangeSensorCreatePrim#

Base command for creating range sensor prims.

This command is used to create each range sensor prim and handles undo operations so that individual prim commands don’t have to implement their own undo logic.

Arguments#

  • path: Path for the new prim.

  • parent: Parent prim path.

  • schema_type: Schema type to use for the prim.

  • translation: Translation vector for the prim.

  • orientation: Orientation quaternion for the prim.

  • visibility: Whether the prim is visible.

  • min_range: Minimum range of the sensor.

  • max_range: Maximum range of the sensor.

  • draw_points: Whether to draw points for visualization.

  • draw_lines: Whether to draw lines for visualization.

Usage#

import omni.kit.commands
import omni.isaac.RangeSensorSchema as RangeSensorSchema
from pxr import Gf

# Create a basic range sensor prim using RangeSensorCreatePrim
result, prim = omni.kit.commands.execute(
    "RangeSensorCreatePrim",
    path="/World/RangeSensor",
    parent="",
    schema_type=RangeSensorSchema.Lidar,
    translation=Gf.Vec3d(0, 0, 1),
    orientation=Gf.Quatd(1, 0, 0, 0),
    visibility=False,
    min_range=0.4,
    max_range=100.0,
    draw_points=True,
    draw_lines=True
