2.5.5 Changes (12/12/01)
ARTMATIC 2.5.5
-Fixed all problems introduced since 2.5.3
-Finalization of packed input/output management in compiled trees. Now packed inputs can be send also in 33 an 22 trees if the recursion is kept at zero.
-Fixed broken dv rendering aspect ratio
-Add 2 additional components in 1 in 1 out
* Fractal Noise
1D fractal noise, similar to other higher dimension fractal noise.
check "Gaz Giant vortex study" for an application example.
* Plateau : a gaussian filter with an extended plateau around zero.
Plateau is useful to delimit a symetrical shape.
the file "flying rectangles" shows how plateau is used to create a rounded corner rectangle primitive.
"flying objects" also uses it.
-Add 2 additional components in 3 in 3 out
-Memory Min : similar in use with Memory Max, Memory Min compute the minimum of input RGB or 3D values.
Useful to accumulate dark graphics on a bright background when iterations are used.
-Colorize:
A color filter function that lets you desaturate and tint incoming RGB. Gives more control
on the colors when placed after the RGB texture primitives.
A : mixes the original with the tinted. At maximum you get a tinted monochrome.
B red balance
C blue balance
-Allow for system with up to 6 CT to be previewed.
-When importing CT within a tree, the CT animation is now correctly mapped into the current keyframes.
If less keyframes are available, more will be created. If the CT animation is undesirable here is a tip to
get rid of it :
-select a frame where the CT values are to your liking.
-open the CT (type "e") on the CT selected tile
-Lock all CT parameters with shift lock
-select/replace all keyframes to save with the now constant values
The example "Alien Butterfly on Wet window" shows how packed inputs can be sent to a 4 in custom shader ct.
Also its a good illustration of the modular use of several CT.
"Surface shaded visualizer B" is a good generic system to visualize any surfaces defined as 21 CT.
it has a cut off level, specular (with color shift) and diffuse component on the derivative.
The colors are the current palette.
I have included two more cool examples of my cosmic series. If you have time,
render both animations, they are pretty amazing.
2.5.3 Changes (11/23/01)
General Notes
More Altivec optimizations. This compile runs somewhat faster on G4's than earlier versions.
And a bunch of small details have been fixed. Here are the main features additions and improvements :
-Context-sensitive preview implemented when loading compiled trees:
The preview inserts the selected compiled tree into the right place in the parent previewing in the dialog box for selecting a compiled tree (without inserting the tree, the preview would be meaningless in many cases).
-fixed loop management (allow for parallel loops) when several iteration component are used in parallel.
-fix 3D viewpoint management :
Offset components in 1D (1-in/1-out) , 2D (2-in/2-out) and 3D (3-in/3-out) all move the virtual camera in 3D space and add displacements throughout the tree. If there are multiple offset components in the tree, the topmost component will be global and will influence all components lower in the tree and controls the whole view. Other offset components move objects individually in 3d space. This allows much more complex 3D animation than was previously possible-- especially because 3D objects within compiled trees are now sensitive to the parent systems 3D offsets.
-Random path animation handles input movies the proper way. The option "use movie own speed is now working. Previously, the delta time influenced the playback speed.
-File search strategy improved : ArtMatic starts the search with folders within the document folder then searches all folders one level higher than the document’s folder. If still unfound, ArtMatic performs a global search on all disks. (To abort the search, press the escape key.)
Practical implication : you can have a folder of shared elements outside the folder that contains the ArtMatic files.
-Resampling pop up added in the Gradient editor
-fix a size problem when saving a vertically-oriented picture
======== COMPONENT CHANGES ========
The range of all offset and phase sliders has been extended to -32 to +32. You can always go higher or lower using the parameter envelope dialog.
1->1 components
-1D. Random is now balanced around zero for sound application. If older files uses the 1D random components you may need to insert an offset component at its end to obtain the same result.
2->2 components
-The old facet space component has been renamed facet space mirrors.
======== NEW COMPONENTS ========
====== 1->1 components
-Quantize : quantizes input to the given number of steps (parameter A). The amplitude (parameter B) has to be at its maximum to have a real quantize. Quantize is great to obtain discontinuous, step-like functions--useful for creating pixelization and color reduction effects.
-sin (Bx) sin(x) good for sound generation (harmonic control)
====== 2->2 components
-Cristallize (similar to a PhotoShop’s Crystallize function) is a new component which is nice for processing video.
-Facet Space. A new component called "facet space" has been added that works like the 3-in/1-out one. The component previously called Facet Space has been renamed (it is now called facet space mirrors)
====== 2->3 components
-Several 3D primitives have been added that offer new parameter options and offer a greater variety of shapes.
-Another useful shaded plain color that sets the a direct rgb color modulated by inputs. When the first input is negative, the complementary color results.
-A new rgb color texture "techno boxes" .

------------ MIN(X,Z),MIN(Y,Z)
------------ Gated distance
------3-in/3-out
------------ Conditional Z set [Great for designing classic-style fractals]
------------ Packed Add & Mul
FIXED BUGS:
