As stated, the fact that OpenCL is standard weighs heavily in determining its future. Having the support of pretty much the entire computer/video hardware industry helps a bit as well. From an ISV (Independent Software Developer) standpoint, OpenCL is is the gateway to hybrid (CPU/GPU) computing. As anyone with scar tissue in the HPC industry can tell you, investing resources and time into non-standard APIs (Applications Programing Interfaces) is a risky business.

...

One final feature of OpenCL should not be overlooked. As mentioned, OpenCL supports data-parallelism and task-parallelism. In the hybrid computing world, there is currently an implied assumption that the GPU is a slave to the CPU, that is the GPU cannot run on its own as it must have a CPU present. Given this assumption, one should be able to write OpenCL programs that can adapt to the hardware environment and run minimally on a single CPU (core). Of course it will run slower, but it will still run. If more cores or GPUs are found in a different hardware environment, then an OpenCL program should be able to adapt to the new hardware at run-time. The rather distasteful alternative is separate binaries for various combinations of CPU and GPU resources.

Nvidia Corp. has blamed its partners among computer makers for frequent re-branding of their products. The company said that original equipment manufacturers (OEMs) need to constantly offer customers something new, which is why Nvidia is forced to rename its old products.

Is it possible to group multiple meshes in a model using lua script ?
Yes, there is no particular problem.


Or even group multiple models together in the same(local) coordinate space, that would be nice :D
Never tried, but that should work...

Actually GeeXLab allows to create a cube with either an single material for all faces or with one material per face.
At least it's things work internally. I have to see if functions to play with the materials of a mesh cube are exposed.

3D-Tech News Around The Web / EVGA GTX275 CO-OP PhysX Edition Review
« on: February 08, 2010, 09:40:27 AM »
NVIDIA and ATI dominate the market for gaming-oriented video cards. But neither company sells video cards directly to the consumer; rather, they produce "reference designs" that are manufactured by a number of "partners". Most partners simply produce the reference design and slap an identifying sticker on the card's cooler; although some might replace the reference design cooler with a quieter or more powerful solution, with few exceptions there's little to distinguish one partner's version of a specific card from another partner's version of the same card. EVGA breaks out of this rut with their EVGA GTX 275 CO-OP PhysX Edition, model 012-P3-1178-TR, which combines NVIDIA GTS250 and GTX275 GPUs on the same card, and Benchmark Reviews takes it around the block to see what it's got.

ATI has always released video cards for just about everyone in every possible price bracket. This normally entails having the most up to date Direct X capabilities on every one of their price bracketed video cards. We all know that Direct X 11 is going to be a reality in our games. Unlike Direct X 10, Direct X 11 is very well optimized and brings to the table a whole slew of newer and exciting features we never have seen before in our games.

What does this have anything to do with ATI releasing affordable video cards? Well, everything. This time around though ATI is releasing a video card that is targeted for people in the sub 100 USD price bracket who just want a video card for their HTPC's or for their casual gaming lifestyle. Gigabyte like many other video card manufacturers has included the 5670 video card into their video card line up. This time Gigabyte has made their 5670 variant overclocked right from the start.

« on: January 22, 2010, 02:57:00 PM »
In GPU Caps OpenCL demos I don't use compiler options with AMD because AMD's CL doesn't support them yet. Only  NV supports them (like -cl-fast-relaxed-math).

But I'm really busy and currently I don't have time to look at this cool python lib.

Have you tried this lib with GeeXLab ? I guess some functionalities will be missing in GeeXLab, but try to have a look (and it will be easier for me to play with a GeeXLab project).

3D-Tech News Around The Web / Windows hole discovered after 17 years
« on: January 21, 2010, 09:38:11 PM »
Link: http://www.h-online.com/security/news/item/Windows-hole-discovered-after-17-years-Update-908917.html

Microsoft isn't having an easy time of it these days. In addition to the unpatched hole in Internet Explorer, a now published hole in Windows allows users with restricted access to escalate their privileges to system level – and this is believed to be possible on all 32-bit versions of Windows from Windows NT 3.1 up to, and including Windows 7. While the vulnerability is likely to affect home users in only a minor way, the administrators of corporate networks will probably have their hands full this week.

The problem is caused by flaws in the Virtual DOS Machine (VDM) introduced in 1993 to support 16-bit applications (real mode applications for 8086). VDM is based on the Virtual 8086 Mode (VM86) in 80386 processors and, among other things, intercepts hardware routines such as BIOS calls. Google security team member Tavis Ormandy has found several vulnerabilities in this implementation that allow an unprivileged 16-bit program to manipulate the kernel stack of each process via a number of tricks. This potentially enables attackers to execute code at system privilege level.

3D-Tech News Around The Web / Anti-Aliasing and Subpixel Accuracy
« on: January 21, 2010, 09:31:25 PM »

Quote
Anti-Aliasing is a very well known technique used to improve the visual quality of images when displaying them on low resolution devices. It's based on the properties of the human vision. Look at the following picture and try to guess what it means.

Well, it's a word drawn with Anti-Aliasing. In terms of Kotelnikov-Shannon's theorem, the maximal frequency of the image is far above of the Shannon limit.

Now look at the same picture that has normal size and within the context. You easily recognize word “stereo”. However, the pictrures are exactly the same. The first one is just an enlarged version of the last one. This very property allows us to reconstruct missing information on the basis of accumulated experience. Anti-Aliasing doesn't make you see better, it basically makes you brain work better and reconstruct missing details. The result is great. It allows us to draw much more detailed maps for example.
