AtomKraft Changelog

This is the log of changes between successive AtomKraft/Nuke releases.

AtomKraft/Nuke 1.0.0 — “Spike”

December 19th, 2011

Major changes

  • Implemented live texturing mode
    When in “live texturing” (on by default) AtomKraft gets image input data directly from Nuke, processing this data is immediate and provides faster interaction. Texture filtering matches Nuke internal one and is processed on the fly. Baking is only done if the option is switched off. AtomEnvironment on the other hand always bakes.
  • Added display cache option
    When active (off by default) AtomKraft caches the rendered image (and any other requested channel) so that you can freely pan & zoom in the viewer without triggering a re-render
  • Upgraded alembic from 1.0.2 to 1.0.3
  • Upgraded rendering engine to 3delight 10.0.18

New Nodes

AtomReflect

A component material that allows fast (glossy) raytraced reflections, with controls over grazing angles, glossiness (blurred reflections) according the BRDF via the roughness parameter, and handles properly raymisses by looking up the environment.

AtomRefract

A component material that allows fast (glossy) raytraced refractions, with controls over Fresnel, glossiness (blurred refractions) via the roughness parameter, and handles properly raymisses by looking up the environment.

AtomIndirect

A user-friendly “Global Illumination” light that adds indirect light, with control over number of bounces & several other optimizations. just Plug & Play!

  • Fixed a bug which exported duplicate parameters in AtomLight.
  • Added workaround, which optimizes AL/ALS shadowing. (#149)

New Nodes

AtomDisplacement

AtomDisplacment is the atomic-powered node to produce displacement effects on arbitrary materials (including Nuke standard ones). Special abilities:

  1. displacement stacking
  2. bump/normal mapping
  3. vector displacement
  4. automatic bound computation

The Atomic Light System

The base node of our atomic light system is the AtomLight node. Added in the previous version as a placeholder, it now comes with full powers: when added to the scene initially AtomLight behaves like an omni-directional point light.
The following nodes all act like light filters/modifiers to AtomLight. Each node’s transform can be parented to AtomLight or to the scene for maximum flexibility.

AtomLightCone

Defines a volume where light is emitted. It can be connected to AtomLight via the “vol” input. Implements and extends the uberlight system, the shape roundness can be controlled (so to fade from a cone to a pyramid trunk), with penumbra and clipping controls. Most of the parameters can be also controlled from OpenGL.

AtomLightDecay

Defines the way the light decays with distance. It can be connected to AtomLight via the “fall” input. Falloff start/stop, cut in and cut out, with fade controls are available. Most parameters can be controlled also form the OpenGL view.

AtomLightCard

Defines what is commonly known in theatrical stage lighting as “gobo” and is also commonly referred as “slide-projector” or “gel”  in cinematographic lighting. We use the more generic and nuke-compliant “card” naming. This card can project a texture. It is connected to AtomLight via the “card” input. Multiple cards per AtomLight node are already supported.

AtomShadow

Adds a shadow to AtomLight with ability to support max distance, adding and other advanced properites. it is connected to AtomLight via the “shad” input.

AtomKraft 0.8.30

April 15th, 2011

Changes

  • New Node: AtomCaptureMaterial - Work in progress version of our simple material capture node. Plug in a photo of a sphere sample of a real world material. Feedback welcome; check the AtomCaptureMaterial docs.
  • New node: AtomLight — Work in progress version of our custom super light node. This is like a lighter’s toolbox. Shadows, blockers, gels, falloffs can all be plugged in to configure this. Not very useful so far since all co-shader are not yet present, just included in this build for giggles.
  • New: Alembic support — Added support for reading Alembic files in AtomReadGeo. The timestamp of a file is now added to the node’s hash. This means that when a referenced file is changed on disk, the node automatically re-reads the file when queried the next time.
  • Added support for smooth cards with handles in AtomCard. This works like a Nuke Card when type is set to ‘bicubic’.
  • Fixed a threading bug which was causing hangs on some particular Mac systems (issue #36).

  • The materials should now render faster when only a ‘cheap’ output (some id, point, normal, motion etc.) is requested.
  • If $ATOMKRAFT is empty and the default locations don’t exist, $NUKE_PATH is now analyzed to find AtomKraft and its dependencies.
  • The Linux installer no longer has the highest found Nuke version selected for symbolic link creation. By default the resp. selection is now empty. The reason is that on Linux most people will prefer using NUKE_PATH, to make AtomKraft known to Nuke.
  • The docs now come in both HTML and EPUB format (Linux only for the time being). EPUB can be viewed on most e-book readers. We suggest Calibre to transfer to your e-book reader device (works with Stanza on an iPhone/iPad/iPod Touch too).
  • Fixed a race condition that could lead to deadlocks when interacting with AtomRender through a viewer.

AtomKraft 0.2

  • Bumped version to 0.2

AtomKraft 0.1.67

  • Completely re-factored display/plugin communication and thread-synchronization code. This needs testing by users!

AtomKraft 0.1.66

  • The Linux version now has an installer script. It runs interactively by default. Try ./install –h for options.
  • Initial documentation structure is there.
  • Point– and spotlights now automatically do ray-traced area-shadows.
  • The light diameter can currently only be set globally on the ‘Light & Shadow’ tab. Note that we still have to switch on
  • trace:displacements when displacements are on. This is due to a bug in 3Delight.
  • Fixed a bug with texture coordinates in material networks.
  • Fixed UVs for all primitives (both built-in and external geo).

AtomKraft 0.1.65

  • FillMat should now behave correctly when alpha < 1 (needs more testing)

AtomKraft 0.1.64

  • Added fake ambient sky/ground shading
  • Added depth computation types to the ‘Output’ tab
  • Added alpha value support to FillMat
  • Added support for global light diameter to create soft shadows (this currently only works for spotlights)
  • Removed ‘trace shadows’ as this was interferring with soft shadows

AtomKraft 0.1.63

  • libIex is linked statically on some platforms now

AtomKraft 0.1.62

  • Output of (world space) _position_, _normal_ and (camera space) _depth_ works
  • The ‘extreme blur sampling’ knob is now a slider, allowing for a speed vs quality tradeoff (1.0 = max. quality and slowest speed)
  • Added ‘ambient shading’ knob (with tooltip) to switch ambient light behavior in standard shaders (BasicMaterial, Diffuse, Phong) between ‘physically plausible’ and ‘Nuke ScanlineRender’ (also known as “pixel dork mode”)
  • Small display driver optimizations
  • Fixed shutter efficiency (the opening value was calculated incorrectly)
  • Added shutter efficiency tooltip

AtomKraft 0.1.59

  • Fixed support for displacement

AtomKraft 0.1.43

  • Added support for overscan

AtomKraft 0.1 — Beta 1

  • Starting of Beta 1 phase, shared to 100+ beta testers

AtomKraft — Alpha

  • First stable version, demoed at the Foundry in London, November 2010
