&&&& 本课题拟采用2009年发布的开源项目osgOcean,它是欧盟联合开发的VENUS(Virtual Exploration of Underwater Sites)的一部分，其目的主要是进行深海探索和勘探的理论方法和技术手段，并采用逼真的模拟手段来重现海洋及海底的真实情景；并与同年七月份在美国的Siggraph会议上进行了介绍及演示。
&&&& osgOcean目前已有的特效有：支持海平面模型的快速傅里叶（FFT）变换、可调波浪大小、水面的反射与折射、水底光照（God Rays）、海面光晕、海底的雾效果等。
&&&&& 将来进一步的开发技术有：通过顶点渲染更好的实时更新海浪的细节；利用CUDA或者OpenCL来加快FFT变换，从而达到更高的帧速；结合VPB（地形数据库创建工具）实现全球的海洋模拟。

Why submit results to SPEC?
SPEC's mission is to develop benchmarking standards and the
corresponding software tools for fairly evaluating modern computer
performance, and to provide an open forum for the results. SPEC invites you
to help populate its public database of benchmark results. Licensees of the
SPEC benchmarks may run the tests and submit results to SPEC. SPEC reviews
the results and publishes them on its website for a processing fee. Having
more results published on the SPEC website means having more information
available to the community to make better comparisons. Help us level the
playing- submit your results to SPEC.
Who may submit results and how much does it cost?
Any individual or group licensed with SPEC software (see our online product order form) may submit results to
SPEC. There is a US$500 publication fee for each result submitted to SPEC,
except in the case of an SPECsfs2014 result
submission where the fee is US$1000. Payment is expected prior to publication
of a reviewed result.
SPEC OSG members and associates may submit an unlimited number
of results for no charge, one of the many benefits afforded by membership to
SPEC. If you expect that you will be submitting more than 12 results in a one year
period of time, you should consider joining SPEC as a member or associate.
For more info on SPEC membership, !
How to submit results?
Results are submitted to SPEC via email. Results may be submitted at any
time on any day of the week (but they are reviewed and published on a
specific schedule). Each benchmark result undergoes a two (2) week
review/publication cycle according to the .
In general, the result or raw result file should be submitted to SPEC as an
attachment to an email to the appropriate benchmark submission drop. For a
list of result submission email drops please send mail to info@spec.org.
Additional and specific information on submitting results can be found in
each benchmark's run and reporting rules and user guide documentation.
Publication of Results
Once OSG submissions complete their review and are considered accepted for publication
at SPEC.org, they will be published (typically within one US business day) on www.SPEC.org
with all the other results for the same benchmark.
for a listing of where
results are published.
All results for currently supported benchmarks are tagged with the date that result was
first published at SPEC.org.
This tagging is commonly implemented as an "Originally published"
string as part of the footer information on each result page.
Note: not all result page formats
support post-proc however, at least the HTML format for each result does
support this tagging.
If no such date string is seen in a specific result file, check the HTML
version of the same result. Several SPEC benchmarks have explicit rules based on a "Date Published"
definitions, and in those cases the result file incorporates the "Date Published" into the main
content of the result page rather than just included as part of the page footer.

To better understand the SPEC result review process, please consult the SPEC/OSG Policy Document, Section: Guidelines
for Result Submission and Review.

Hi,Here is my setup:-- Intel Core 2 GHZ-- 3G RAM-- Nvidia GeForce GTX 260 (drivers: 6.14.11.-9)-- winxp sp2,vs2005-- osg2.8In single monitor mode everything is working fine.When I run my application,CPU usage is a constant 10%~15%.But when I use two monitors and set the Nvidia card to "TwinView" mode ,the CPU usage dramatically raise to50%.It is basically using an entire CPU core since I use a 2 core machine.Then I find the same problem happens whenI run any OSG example or any OSG application in TwinView mode!It is OK when I use other multi-monitor mode such as"pan mode".So I think maybe it is something wrong with the OSG2.8 and the "TwinView" mode of Nvidia card?Any one can help me?Thank you!Cheers,Lv------------------Read this topic online here:http://forum.openscenegraph.org/viewtopic.php?p=

您是不是想找SPEC OSG-CPU Result Submission/Review Calendar [2018]
SPEC OSG-CPU Result Calendar:
| CPU2006 |
Result submission and final review dates are marked in blue, bold text.
The current two-week result review cycle is marked in pale blue. Current
month and date are marked in purple. The current date will be marked in red
if it's a submission deadline/final review date.
Results must be successfully placed in the submissions queue prior
to the beginning of the upcoming review cycle if they are to be reviewed
during that period.
Review cycles begin at 03:01 Eastern US Time
(00:01 Pacific) on the days noted below.
Email result submissions are checked for basic syntax errors by the
automated results processor upon receipt.
If there are errors, the
result is returned to the sender so it can be corrected and the submission
otherwise, the result is assigned a tracking number, inserted
into the submissions queue, and acknowledgement of a successful submission
is sent to the submitter via email.
To enter the upcoming review cycle,
a result must be successfully received at SPEC and assigned a tracking
number prior to the submission deadline, otherwise it will be held for the
following cycle.
SPEC Cloud IaaS 2016 and SPECvirt_sc Submission Review Cycles:
A new two-week review cycle begins for SPEC Cloud IaaS 2016 and
SPECvirt_sc
results each Wednesday at 3:01 AM Eastern US Time.
A result received after
the Wednesday deadline will begin its review on the following Wednesday (e.g.
a submission received at 5:00 AM Eastern on Wednesday will enter review at
3:01 AM on the following Wednesday rather than being held for two weeks).
Result Publication
At the end of a review period, the responsible subcommittee will determine whether
the result can be published on the SPEC web site. In some cases, results may be
held pending actions. In some cases, SPEC will not publish a result due to run
rule compliance issues. For more detail on the review process, see
