Detailed Description

Renders a glowing outline using a image processing pass.

Create a glowing outline of the image rendered by the delegate.

This render pass was designed to highlight parts of a scene by applying the render pass to a layered renderer on top of the main scene. For optimal results, actors that form the outline should be brightly colored with lighting disabled. The outline will have the color of the actors. There is only one outline around all objects rendered by the delegate.

This pass expects an initialized depth buffer and color buffer. Initialized buffers means they have been cleared with farthest z-value and background color/gradient/transparent color. An opaque pass may have been performed right after the initialization.

The delegate is used once.

Its delegate is usually set to a vtkCameraPass or to a post-processing pass.

This pass requires a OpenGL context that supports texture objects (TO), framebuffer objects (FBO) and GLSL. If not, it will emit an error message and will render its delegate and return.

Implementation:
The image is first rendered to a full size offscreen render target, then blurred twice on a half sized render target using Gaussian blur with an offset. The offset and the smaller render target increase the size of the outline without incurring the cost of a big Gaussian blur kernel. The implementation of the gaussian blur is similar to vtkGaussianBlurPass with the alterations described above.
