Count the number of contacts per (sensor, filter) pair.

Populates counts with shape [numSensors * filterCount]; each cell holds the number of contacts that would be written by :func:launchContactData for that pair.

Parameters:

• contactCount – Device pointer to the physics contact count.

• shape0 – Device array, contact pair shape A indices.

• shape1 – Device array, contact pair shape B indices.

• shapeBody – Device array mapping shape index to body index.

• bodySensorMap – Device array mapping body index to sensor index.

• bodySensorMapSize – Length of bodySensorMap.

• bodyFilterMap – Device array mapping (sensor, body) to filter index.

• numBodies – Total body count in the model.

• filterCount – Number of filters per sensor.

• worldBodyIdx – Sentinel body index representing the static world.

• counts – Device output counts, shape [numSensors * filterCount].

• rigidContactMax – Capacity of the contact arrays.

• stream – CUDA stream.

Returns:

true if the launch succeeded.
