Note: This class simply stores the light parameters and relies on an external task (HdxSimpleLightTask) to upload them to the GPU.

overridevirtual |
Finalizes object resources.
This function might not delete resources, but it should deal with resource ownership so that the sprim is deletable.
Reimplemented from HdSprim.
Accessor for tasks to get the parameters cached in this object.
|
overridevirtual |
Returns the minimal set of dirty bits to place in the change tracker for use in the first sync of this prim.
Typically this would be all dirty bits.
