matrix [] agentclipsampleworld(<geometry>geometry, int prim, int clipindex, float time)
matrix agentclipsampleworld(<geometry>geometry, int prim, string clipname, float time, int transform)
matrix agentclipsampleworld(<geometry>geometry, int prim, int clipindex, float time, int transform)
Evaluates the clip at the given time and returns the world transforms of the agent’s rig.
Returns an empty array if clipname is not one of the agent’s animation clips, prim is out of range, prim is not an agent primitive, or transform is out of range.
The matrix signature is more efficient than the matrix[] signature for sampling a single transform.
<geometry>
When running in the context of a node (such as a wrangle SOP), this argument can be an integer representing the input number (starting at 0) to read the geometry from.
Alternatively, the argument can be a string specifying a geometry file (for example, a .bgeo) to read from. When running inside Houdini, this can be an op:/path/to/sop reference.
prim
The primitive number.
clipname
The name of the animation clip.
clipindex
Index of a clip in the agent’s definition. A clip’s index can be obtained via agentfindclip.
time
The time (in seconds) to evaluate the clip at. If this time is greater than the clip’s length, it will be wrapped around.
transform
Index of a transform in the agent’s rig.
Examples ¶
Sample the world transforms of the walk clip after 1.2 seconds.
matrix xforms[] = agentclipsampleworld(0, @primnum, "agent1_clip.walk", 1.2);
