Detailed Description

A task for visualizing non-color AOVs such as depth, normals, primId.

Different kernels are used depending on the AOV: Depth: Renormalized from the range [0.0, 1.0] to [min, max] depth to provide better contrast. Normals: Transform each component from [-1.0, 1.0] tp [0.0, 1.0] so that negative components don't appear black. Ids: Integer ids are colorized by multiplying by a large prime and shuffling resulting bits so that neighboring ids are easily distinguishable. Other Aovs: A fallback kernel that transfers the AOV contents into a float texture is used.

This task updates the 'color' entry of the task context with the colorized texture contents.

Member Function Documentation

HDX_API void HdxVisualizeAovTask::_Sync ( HdSceneDelegate delegate,
HdTaskContext ctx,
HdDirtyBits dirtyBits 

Implements HdxTask.

HDX_API void HdxVisualizeAovTask::Execute ( HdTaskContext ctx)

Execute Phase: Runs the task.

The execution phase should trigger render delegate processing, such as issuing draw commands.

Task execution is non-parallel and ordered.

The task context is the same as used by the prepare step and is used for inter-task communication.

Implements HdTask.

HDX_API void HdxVisualizeAovTask::Prepare ( HdTaskContext ctx,
HdRenderIndex renderIndex 

Prepare Phase: Resolve bindings and manage resources.

The Prepare phase happens before the Data Commit phase. All tasks in the task list get called for every execute. At this time all Tasks and other prims have completed the phase synced.

This is an opportunity for the task to pull data from other prims (such as a camera prim) by querying the render index.

The task can also use the phase to create, register and update temporary resources with the resource registry or other render delegate specific mechanism.

Tasks are always "Prepared" in execution order.

Inter-task communication is achievable via the task context. The same task context is used for the prepare and execution phases. Data in the task context isn't guaranteed to persist across calls to HdEngine::Execute().

Implements HdTask.
