Hi all and happy new year!
First of all I've cleaned up all the spam that had accumulated on the
forum and updated PHPBB to the latest version. I might have deleted a
couple of legitimate accounts there however none with posts. Sorry if
you were caught in the friendly fire.
Lately I've been working on a Windows interface for CSP. What remains to
be done is the packaging and the documentation. A few new features were
added:
- Super-sampling:
Long requested feature. Smooths the jagged edges on solid mode renders.
7 different levels: 2, 3, 4, 8, 15, 24 and 66. Super-sampling will
improve quality of Liquid and Plasma modes, especially on foreground
surface edges. It will greatly improve the quality of Solid rendering.
Super-sampling only requires two extra bytes per pixel regardless of the
number of samples. It also requires the attractor to be rendered for
each sample or pass, i.e. setting the number of samples to 15 will
multiply the rendering time by 15. The Solid mode however is an
exception: The first pass will take as long as a normal,
non-super-sampled render, but subsequent passes will be relatively
faster as light buffers are only calculated once. Gas and Light modes
will not benefit from super-sampling as long as the anti-aliasing is on.
- Anti-aliasing always on:
This is only relevant for future projects where the anti-aliasing will
be disabled by default.
- Opaque always on (Solid only):
When used, the attractor is completely opaque and the transparency
buffer is used to render perfectly anti-aliased edges between the
attractor and the background. Shadow edges go through the same process.
Overlapping edges between different parts of the attractor are not
anti-aliased. Opaque and super-sampling can be cumulated.
- Ambient occlusion: (Solid only):
Method that greatly improves the ambient light realism. Only noticeable
on parts of the attractor that don't receive any light. It doesn't slow
down the render as it is calculated when the image is saved.
- Saturation:
Boosts the vibrancy of colours in all modes. It's especially good at
counterbalancing the tendency high gamma has to produce "washed out" images.
- Resize:
Allows the user to resize all renders by a given percentage. Iterations
are scaled accordingly, i.e. if you resize the render by a factor of 10,
the number iterations will be divided by 100.
- Animate:
Produces a batch of numbered images showing the attractor rotating
around the Y-axis (microwave style). Original rotation is preserved,
i.e. the first image will be identical to the original project.
All these will feature in the next version of Chaoscope.
I'll let you know when the install is ready for download. Subscribers
will get a chance to play with the Batch Renderer before the release is
public.

Nicolas Desprez
