//----------------------------------------------------------------------------- |
|
// |
|
// Class to composite deep samples into a frame buffer |
|
// Initialise with a deep input part or deep inputfile |
|
// (also supports multiple files and parts, and will |
|
// composite them together, as long as their sizes and channelmaps agree) |
|
// |
|
// Then call setFrameBuffer, and readPixels, exactly as for reading |
|
// regular scanline images. |
|
// |
|
// Restrictions - source file(s) must contain at least Z and alpha channels |
|
// - if multiple files/parts are provided, sizes must match |
|
// - all requested channels will be composited as premultiplied |
|
// - only half and float channels can be requested |
|
// |
|
// This object should not be considered threadsafe |
|
// |
|
// The default compositing engine will give spurious results with overlapping |
|
// volumetric samples - you may derive from DeepCompositing class, override the |
|
// sort_pixel() and composite_pixel() functions, and pass an instance to |
|
// setCompositing(). |
|
