抢先体验了一下 Octane GPU 实时/离线渲染器 demo 版，这个版本首次支持 Fermi

Edison

这是设备参数界面，其中的 CUDA 设备频率识别并不正确，这是因为目前 NVIDIA 的 CUDA API 还没正式支持 Fermi 的特殊频率设计，不过这并不影响性能测试结果。

CHANGES and Bug Fixes since v1.02 beta2
---------------------------------------

- material and autofocus picking on different resolutions and after panning/zooming the image now works correctly
- more stability when changing render resolution while rendering
- bottom part of image is correctly displayed when navigating with supersampling
- roughness of glossy materials can go lower than min 40, and does'nt produce fireflies anymore
- bump mapping sampling of large maps is corrected.
- vignetting does'nt dissolve image gamma on edges anymore (eg works in HDR space)
- linux version can now read .PNG image file format
- fixed issue with diffuse transmission being connected by default on diffuse materials giving incorrect shading
- render hour timer issue is fixed.
- loading of files with non minor case .obj is fixed
- 16bpp grayscale images and 32bpp HDR grayscale images are now working on all platforms
- CMD+Q quits the application on Mac OS X
- Mac OS X version does'nt crash on exit anymore
- OBJ material import adds scale parameter
- nodes can be renamed correctly now
- Mac OS X does'nt need specific order of cuda package installation and the making of the symbolic link
  to the cuda runtime anymore.
- large nodes scroll more smooth/fast in node inspector

- fixed CMD+left click for multi material picking on mac OS X
- fixed incorrect camera raster horizontal position issue
- additional optimizations for fermi architecture
- fixed issue when closing the application and not asking to save/cancel
- Command shortcuts added for Opening (CTRL/CMD O - open), New (CTRL/CMD N - new), Save (CTRL/CMD S - save)


Limitations
-----------

- No Import of RenderMan RIB files.
- No MLT Sampling, this means some scenes present 'fireflies' eg bright pixels/dots,
which are a natural side effect of unbiased algorithms.
The commercial versions of Octane Render will feature MLT and other options which take care of this issue.

RIB, Collada and MLT will be made available in the beta3.

Please note that this release is an incremental update towards the complete v1.0
with all planned features as on our product page.

System Requirements
-------------------

PC / Windows
------------

This release requires a PC with a Cuda capable video card
and the MS Windows Operating System (Windows 2000 or higher).

If you have a 64bit capable version of windows, we highly recommend downloading our x64 version,
as it allows you to load much larger datasets.

To check if you're GPU is Cuda capable, please refer to this list:
http://www.nvidia.com/object/cuda_learn_products.html

This release requires the any of the following Cuda/Video Drivers to be installed:

http://www.nvidia.com/object/cuda_get.html

Geforce Desktop Cards:         NVIDIA Driver (197.13)
Geforce Notebook Cards: Notebook Drivers for Windows XP, Vista, 7 (197.13)


PC / Linux
----------

The package FreeType (freetype2) needs to be installed.
Please use your distribution's package management system to install it prior to running Octane Render.

Linux users also need to install the CUDA toolkit available here:
http://www.nvidia.com/object/cuda_get.html

Download and install the CUDA toolkit version 3.0 for your distribution.

Download and install the latest drivers from nvidia with support for cuda 3.0 for your distribution.
At the time of writing these are:

http://www.nvidia.com/object/cuda_get.html

Developer Drivers for Linux (195.36.15)


Apple Mac
---------

This release is supported on:

- Mac OS X 10.5 Leopard
- Mac OS X 10.6 Snow Leopard

To run Octane Render, you need a Mac computer with an Nvidia Geforce 8000 or higher Video card, and an Intel CPU.

Prior to running the mac installer package, install the Cuda 3.0 drivers for Mac OS here:

http://developer.nvidia.com/object/cuda_3_0_downloads.html

Developer Drivers for MacOS

and the CUDA Toolkit v3.0, on the same page.

NOTE: It's important to install the drivers and cuda toolkit before you install the Octane Render mac package.

This is the first release of Octane Render for Mac OS X if you have any issues please consult us on our forums.


NOTE: If the right mouse button does not work on your mac, eg it does'nt pan the view, use the CMD + mouse instead.


ADDITIONAL NOTES
----------------

We cannot guarantee that the software will function correctly with any other driver,
including newer beta drivers.

Users with low-end video cards, such as most low-end laptop GPU chipsets,
or cards like 8400, 8600, 9400, 9600 series should'nt expect any decent performance,
we suggest upgrading to a newer mid-range or high-end GPU in the GTX260 or higher class.


Known Limitations and other issues
----------------------------------

Please note that this is a betaversion, there are still a few rough edges that we are ironing out.

- We recommend changing the render resolution before loading any mesh object/starting the engine.
changing the resolution during rendering might cause problems with some cards.

- Keep an eye on your Device Manager's memory usage graph (File -> Device Manager),
when working with large scenes or scenes with lots of textures.
The engine will alert you when you're trying to load more data into your GPU than can fit.
We are working on intuitive solution to automatically take care of these situations.

- Please report any major problems on our forums, situations where you can't get octane to work.
With your help we can make sure these issues are solved as fast as possible.

- Note that we have not done extensive testing with various 3d modeling applications
with regards to export/import of OBJ files.
Please report any issues you might have on our forums.

USE
---

We would like to point you to the demo video on the website's videos page for a quick introduction on how to use the software,
and don't hesitate to ask questions about it's use on our forums.

Some quick tips to get you started:

To load and object, right click in the nodegraph editor window (bottom left),
and add -> object -> mesh.
You can fine tune your import settings with File -> OBJ Import Preferences.

To Access the preview configuration, and change the renderer configuration,
double click on the 'macro' node that's visible by default in the nodegraph editor,
which will open this macro and give access to the different nodes that make up the render preview configuration,
by clicking on these nodes, you can change the parameters in the node inspector panel on the right.

Use the material picker on your render to select materials. (little glass ball with pipette icon on top of render viewport)
Use the 3 buttons with small to large checkerboards to change the subsampling resolution,
if the navigation gets too slow with a more complex model.
