Superclass: vtkDepthPeelingPass Dual depth peeling is an augmentatation of the standard depth peeling algorithm that peels two layers (front and back) for each render pass. The technique is described in "Order independent transparency with dual depth peeling" (February 2008) by L. Bavoil, K. Myers. This algorithm has been extended to also peel volumetric data along with translucent geometry. To use this feature, set VolumetricPass to an appropriate RenderPass (usually vtkVolumetricPass). The pass occurs in several stages: 1. Copy the current (opaque geometry) depth buffer into a texture. 2. Initialize the min-max depth buffer from the opaque depth texture and the translucent geometry. 3. Peel the nearest and farthest fragments: 3a. Blend fragments that match the nearest depth of the min-max depth buffer into the front buffer. 3b. Write the far depth fragments into a temporary buffer. 3c. Extract the next set of min/max depth values for the next peel. 3d. Blend the temporary far fragment texture (3b) into an accumulation texture. 3e. Go back to 3a and repeat until the maximum number of peels is met, or the desired occlusion ratio is satisfied. 4. If the occlusion ratio != 0 (i.e. we hit the maximum number of peels before finishing), alpha blend the remaining fragments in-between the near and far accumulation textures. 5. Blend all accumulation buffers over the opaque color buffer to produce the final image.
