bool isaacsim::physics::newton::tensors::launchGatherFloatStrided(

const float *src,

float *dst,

const int *devIndices,

int numIndices,

unsigned dstStride,

void *stream = nullptr,

)

Gather scalar floats by index, writing zero for -1 entries.

dst[i * dstStride] = devIndices[i] >= 0 ? src[devIndices[i]] : 0.0f for i in [0, numIndices).

Parameters:

• src – Device pointer to the source scalar array.

• dst – Device pointer to the destination array, length numIndices * dstStride.

• devIndices – Device index array, length numIndices.

• numIndices – Number of gather slots.

• dstStride – stride for writing to destination.

• stream – CUDA stream to launch on.

Returns:

true if the launch succeeded.
