Indigo Renderer 2.4.4 Beta

Post by lycium » Sun Jun 06, 2010 6:49 pm

Hi all,

Included in this beta release are all the new GUI and core changes so far, except for GPU acceleration support which will be released to the beta testing group shortly. There have been a great many changes, a lot of very new and untested stuff, so this is really a beta release - not recommended for production environments! The biggest changes are to be found in the GUI and single directional path tracing modes.

Single directional path tracing is now much more efficient, and should be preferred over bidirectional in simple illumination settings - reasonably large area lights and limited caustics. In such scenes the rate of convergence is a big improvement over bi-bidirectional, and GPU acceleration further improves this.

The GUI has had a facelift, sporting fantastic new icons made by Godzilla and a number of usability improvements, added features and bugfixes. We've added the ability to easily toggle among the four rendering modes in the GUI, so you can quickly see which is most effective for your scene.

Colour noise has been vastly reduced in this build, at the cost of a small (less than 10%) performance hit. Triangle meshes now use substantially less memory, saving and loading of large IGI files is fixed... see the changelog below for more details, even this list isn't entirely complete!

The BVH accelerator is often faster than kD trees now, especially in exterior scenes. Interior scenes can still be faster with kD trees sometimes, though you might want to tell your exporter to use BVH via the triangle count threshold setting to experiment.

Your testing is greatly appreciated, thanks :)


Windows 32 bit build:
IndigoRenderer_2.4.4_Setup.exe

Windows 64 bit build:
IndigoRenderer_x64_2.4.4_Setup.exe

Mac OSX (32 and 64 bit) build:
indigo.osx.2.4.4_6.zip


Changelog:
2.4.4
* CUDA, OpenCL support (not exposed in this build)
* Indigo components now launch using below normal priority by default
* Many GUI improvements
* BVH, motion blur much faster now, many other localised performance increases
* Lower memory usage for triangle meshes
* Much less colour noise
* Much faster and slightly more accurate sampling
* Much more efficient single directional path tracing
* Fixed saving and loading of large (multi-gigabyte) IGI files
* Fixed image update affecting colour balance

why isnt default rgb in light layers 1/1/1? That new RGB values are making pinky GI.

In the beginning, there was no light layer colour scaling. Then we added XYZ scaling, but that colour space isn't really intuitive to people, so we changed it to RGB. However, RGB = 1,1,1 gives a different scaling to XYZ in which the image is represented.

So the default RGB colours now are ones that leave the image unchanged in XYZ space, and adjusting in RGB space should work as expected.

Thanks Lycium

First thing i notice is that the icons are getting oddly re-sized which makes them appear blurred..


On the top is my 'altered' version of 2.4.3, and on the bottom is 2.4.4

Cool interface. Thanks.

I found some problems.
I got some color noise.
This picture's Render Mode is Path Tracing.
Similar noise with Bi-Directional Path Tracing too.

Is this bug or
Have I made a mistake in the setting?

I added a picture with Aperture diffraction.
[Edit] I deleted a picture with Aperture diffraction because it's already reported.

I can not wait for the GPU version. ))) This version I compared it to Maxwell, Indigo is slower. Perhaps because in Indigo is enabled by default dispersion?

@Yoruneko: I already posted a bug report here:

Besides that, great release! :)

I can confirm this, I ran into the same two problems with this test-scene.

I even rendered a bigger version (1920x1200) and let it run for more than 6 hours to see, how the color noise develops.

Will be fixed in the next release... forgot about the command line parameters :)
