Performance:
Pixarra's attention to performance is a top priority.
As an artist draws and paints the tools should
disappear from thought and allow focus on the creative
process rather than waiting for the tool to finish its
job. In addition the responsiveness of the brush
tools should be quick and show marks on the page instantly to
allow the artist to enter the "zone".
High
Precision 64 Bit Brush Engine: Most graphic programs
offer at most 32 bits of color resolution. TwistedBrush
represents all image data internally at a full 64 bits
of color resolution. This allows for super smooth
color mixing and alpha blending.
Brushes:
TwistedBrush has over 1500 diffferent brushes included.
These range from very simple color dots to realistic
representations of natural artist tools to very wild
brushes. Here is a very small sampling of
some of the brushes that are available. For a
complete listing of brushes visit
the ArtSet swatches.

|
Airbrush:
Smoothly feathered at the edges as you'd expect
an airbrush would be. This brush dab was done with no
additional brush effects.
|
| 
|
Watercolor
crayons: Drawing with a textured wet
watercolor crayon with color blending and
some grainyness.
|
|

|
Oil pastel: Even
more grain shows in this brush, but it still
blends with the existing color that is already
on the page.
|
|

|
Gausy brush: Actually
created with the basic oil pastel brush
style but altered with a multiply and jitter
brush effect.
|
|

|
Fine oil brush:
Based on one of the basic brush types
that draws with individual bristles of color,
dynamically changing with each stroke. This
basic brush with modified with the multiply
and jitter brush effects.
|
|

|
Color pencil:
A basic color pencil brush type but with
a darken color blending
brush effect. Brush effects that blend
colors allow for a variety of on the fly
color mixing. In this case blue strokes
were drawn first. The red strokes
when drawn blend with the blend stroke just
like color pencils where lighter colors
don't overlay darker colors. However
notice the yellow, with repeated stroking
the lighter color can overlay the darker
blue.
|
|

|
Wet watercolors:
A brush that blends and dilutes with the
color that is already on the canvas.
|
|

|
Thick oil paint:
Each bristle mark is visible with each pushing its
way throught the paint that is already layed
down.
|
|

|
Vegas scarf: Brush
effects are used here to alter the basic
realistic brush type to create a brush that
doesn't exist in reality. In this
case the spike effect is used to give the
overall feeling of the storke.
|
Paper
Textures: A wide variety of paper and canvas textures
can be selected so that brush strokes respond with the
texture as they are placed on the paper or canvas.
|

|
The textures are
easily selected from the main workspace.
|
Filters:
Over 50 filters can be used to quickly alter and adjust
your image. The includes basic photographic filters
that adjust brightness and contrast or equalize the
colors, artist filters that allow you to mimic
a oil painting with a click of the mouse, blurring filters,
noise filters, noise generation filters, distorting filters,
sharpening filters etc.
Tracing
Paper: A source image is shown below the current
paper as if the current paper was as thin as tracing paper.
This allows for using a photograph or another
drawing as a guide when doing a new picture. With
a press of the hot key the tracing paper is turned off
and on allowing you to check on your progress.
|

|
Source Image:
This is the source image that will be traced.
It appears as the previous image in
the sketchbook.
|
|

|
Drawing Image:
This is the paper that is being drawing
on. Notice that the source image is
visible but appears
faded, just like looking through tracing
paper. Also notice the black marks
on the left hand side, that is were some
drawing is taking place using the image
of the flower as a guide.
|
Cloners:
Related to the Tracing Paper feature Cloners are brushes
that have a Trace Blend or Trace Color brush effects
applied to them. Used in combination with the
tracing paper feature, when on not only does the source
image show through but the color that is used for the
drawing is based on the color of the source image rather
then the color that is currently selected. This
use in combination with the other powerful brush effects
makes for a very realistic representation of a painted
or drawn version of the source image. An entire
ArtSet of 60 brushes is included that has a variety
of cloning brushes.
|

|
Source Image:
Here is portion of a flower picture that
is used as the source image for cloning.
|
|

|
Resulting Image:
Here is the same portion of the flower picture
that is now cloned. This was created with
just 1 of the 60 cloner brushes. Notice
the brush strokes and color mixing, just
like as if it was painted. It's a
fun process because the artist must still
paint each stroke on the page, following
contours or not, choosing the type of cloning
brushes to use etc. It's not a single
click process and allows room for creative
expression.
|
Masks:
With masks part of an image can be protected from
changes. This works just like traditional artist
masks or friskets. There are numerous ways to
create and edit masks, they can be painted on with masking
brushes, added to with special masking tools for rectangles
and ellipses, the masking magic wand can be used to
mask area of similar color or you can even convert and
existing image to a mask.
Layers:
Imagine overlaying sheets of clear drawing material
on top of each other and being able to freely paint
and draw on each layer. This is the idea of layers.
A powerful system of image creation that allows
for continued editing on a image even after it is nearing
completion. For example if painting a landscape.
On the background layer place the general tone of
the picture blocking in color areas. On the next
layer up paint the sky, next the clouds, next distance
land or trees, another layer for middle ground
areas, and last for the foreground. If you decide
to repaint the clouds no problem go back to the cloud
layer and touch them up or start the clouds from scratch.
The other areas of your work are not affected.
This is just
part of the power of layers, layers can also be made
semi-transparent to give various coloring effects, and
layers can be blended togather with a large assortment
of mixing modes. The blending modes support include,
mulitply, screen, darken, lighten, difference, negation,
exclusion, overlay, hard light, soft light, dodge, burn,
reflect, glow, add, subtract, texturize, alpha filter,
alpha black outline, alpha overlay outline and alpha
highlight.
ArtSets:
Within TwistedBrush is the brush collection idea called
ArtSets. An ArtSet is a collection of up to 60
brush presets. A brush preset can be everything
about a brush, including color, size and of course the
type of brush and effect. With ArtSets similar
brushes can be grouped together for ease of use. A
large number of ArtSets are included with TwistedBrush, but
anyone can create there own, it's as easy as clicking
on an emply brush slot.
|

|
Essentials ArtSet:
Just one of the ArtSets included with TwistedBrush.
This one includes a number of basic brushes
and tools grouped together.
|
Scripting:
A macro system to record most actions within TwistedBrush
and later play them back. This could be an entire
picture from start to finish or a common action that
needs to be repeated. Scripts can be saved to
file and shared with others. It's a great learning
tools to record a script and share it with somepne so
they can see how you created an image.
|

|
Pear Script:
Here is a sample script output, reduced
in size for this website. This entire
drawing as it was created was recorded and
now can be played back over and over again,
showing each stroke as it was originally
drawn, but at a bit faster rate.
|
Script
Brushes: Bringing together the powerful brush engine,
ArtSet and the scripting system, results in Script Brushes.
A script brush is a script that can be treated
like a brush, and therefore can be placed in an ArtSet
and drawn with, relative to the position on the canvas
that you paint rather then the original recorded location.
This is an innovative system that surpases clip
art or canned images used for composition. Since
the script is played back and therefore is just like
it's being drawn for the first time it can properly
interact with the colors that are already on the page.
|

|
Planet Script
Brush: Here is the sample output of a script
brush. Since it's a brush, to use
it is as easy as selecting the brush from
an ArtSet and clicking on the page where
you want the planet drawn. It is not
a saved image! It is redrawn each
time you click.
|
Undo/Redo: Yes
there are multiple levels of undo and redo. Up
to 50 levels in fact, memory permitting.
File
Formats: Most standard image formats are supported.
This Include, JPEG, GIF, PNG, TIFF, TGA, PCX,
PSD, BMP, PCD, WMF and EMF.
Sketchbook
Paradigm: Twistedbook is designed around the concept of a sketchbook. This allows for
quick understanding of what is required to use the software. The first time you
start TwistedBrush page 1 of book 1 was visible and available for drawing on.
Compare this to most other art programs where you must tell the software that
you want to create a new page as your first action. When you are ready to
move on to a new page in TwistedBrush you simply turn the page, your work is
automatically saved. Just like a real sketchbook, you wouldn't expect
your work to disappear just because you turned the page.
In TwistedBrush you can have an unlimited number of sketchbooks each with up
to 100 pages. Pages in a book will default to the same size or they can all be
different sizes. When you proceed to a new page in the book that does not exist
yet the page size used will be that of the previous page
TwistedBrush
has been designed from day one to be easy to use. Many
art program overload the user with countless widgets
and gadgets on the screen often making the drawing area
a second class consideration. Since TwistedBrush is
a artist creation tool, the drawing area remains the
focus with all the basic tools easy to access.
Drawing
Tablet Support: Using the universal Wintab tablet
driver system most all drawing tablets are supported
and allows for pressure sensitive assignment to brush
size, density, opacity and to any of the nearly 200
brush effects!
Brush
Effects System: Brush effects are an advanced part
of TwistedBrush and need only be understood by those
artists wishing to create their own brushes. It
is an extremely powerful system that allows for an incredible
variety of brushes to be created. It is in effect
(pun intended) it's own specialized programming language
and continues to grow and expand with each release.
There are nearly 200 different brush effects that numerous
brush effect envelopes that further modify the effect
over time. A very small sampling of the effects
include, scatter, jitter, orbit, burst 25, spike, tangle,
lineto, radial, spin, spiral1, blend multiply, mask,
mask paint, erase mode, draw gate, filter, scrumble
2, mirror page, kaleidoscope, 3D top left, matrix 3,
circle 32, opacity, blend trace, color trace, hue rnd,
etc.

Spiral Galaxy
Brush Effects Sample: Here is a series of
8 effects that modify an simple brush type
and creates (see below) a spiral galaxy
with a single stroke of the brush. This
is a very advanced brush and is part of
the SpaceScape ArtSet. Note: most
brushes are not this complex.
|
|

|
Spiral
Galaxy Brush Effects Sample Output: This
is the output of the brush effects shown
above.
|
Random
Brush Generation: With a single press of the hot
key a new random brush can be created, combining basic
brush types, with colors, and effects resulting in a
nearly infinite number of possible brushes. Many
of core advanced brushes in TwistedBrush were discovered
through the use of the random brush generation and random
brush explorer system.
Brush
History: Records each unique brush you use while
creating an image and builds a Brush History ArtSet
automatically. This is handy since there are hundreds
of different brushes available in TwistedBrush it can
be a challenge to keep track of your favorite brush
you used while working. Of course you could manually
create your favorites ArtSet with a click of the mouse
/ pen, but this does it for you.
Photo
Editing: While TwistedBrush is designed for the
artist wishing to draw and paint original images, the
tools are present to do the photo editing you need for
high quality results. Image scaling with advanced
algorithms such as bicubic, B-Spline, and lanczos3.
Cropping, rotating and other basic image manipulations.
The photographic filters you'd expect to find,
masking, layers etc. And if you need to touch
up an area, you might just find a brush or two!
Free Upgrades
