ratGPU 0.8.0

- Added an option in the standalone renderer app to re-install the Max/Maya's plug-ins.
- Optimized a 2% the speed in some cases.
- Removed the dependency on TBB.
- Adjusted the bias parameter a bit more.

xN4 delayed to 2015

Sorry, but we're delaying xNormal 4 to 2015-H2 because:

1. We were expecting solid OpenCL 2.0 drivers some months ago, but it didn't happen. We're taking B plan meanwhile they mature : CUDA.

2. Need hardware tessellation support in Macs ( OpenGL 4.2 ). Currently, only 3.3 is supported ... But we'll likely wait for Vulkan and DX12 instead.

3. Some 3rd-party libs still have problems compiling due to C++11/14. We have submitted some bugs and we hope they could fix them soon.
4. clang has some problems with OpenMP with OSX atm.
5. Need at least Qt 5.4 on Ubuntu 14.04LTS installed from standard repository. Currently only 5.2.1 is supported.

6. We want to add ARM support too.

7. xNormal 4 will use a completely new core based on ratGPU 2.0.

8. We're addicted to WoW ( new expansion coming out! ) and Interstellar's trailers. Seriously.

xNormal 3.18.9 and ratGPU 0.7.3

For xNormal, fixed a bug position-offseting the cages.
Also, recompiled with latest JRE and Optix 3.6.2 which should support Maxwell cards.

For ratGPU, fixed a bit the bias parameter so the self-occlusion problems should be fixed on Mac now. Also recompiled with the latest Qt, VS and tbb libs.

Now I'm 100% concentrated in xN4 !

xNormal 3.18.8 and ratGPU 0.7.2

Added 3dsmax/Maya 2015 support and fixed some bugs for xN 3.18.8.

ratGPU 0.7.2 is now compiled with the latest libraries and compilers ( gcc 4.8.2 / VS2013-u2 ) for maximum performance. Also, now it renders two tiles per OpenCL device in order to maximize the speed ( that's the "HT" signature on the device list ... aka GPU 'Hyperthreading' :D )

xNormal 3.18.6

xNormal 3.18.6 released:

- Now the result from the base texture bake is linearly filtered, resulting in better quality.

- Modified the dilation filter's algorithm to consume much less memory. Also, modified the internal image structs to be more SIMD-friendly.

- Increased the maximum render size to 32k x 32k.

- The 3dsmax SBM exporter now saves data from current frame instead of using the first frame.

- Now you can render a new map : the translucency map, which can be used to simulate semitransparent objects and SSS.

- Recompiled using the latest libraries ( FBXSDK 2014.2, JRE 1.7u45, libpng-1.6.7, lua 5.2.3, OpenEXR 2.1.0 ).

ratGPU 0.6.0 and xN 3.18.4 released

For ratGPU 0.6.0, I've optimized it a bit more for Radeon cards and recompiled it using the latest libraries. Radeon 7990 is the new king.

I've also released xNormal 3.18.4 which corrects some bugs.

Some things I will never understand

1. Apple, the OpenCL's founder, does not support OpenCL for the iPad ...
This will only not help to compute faster but also will help to be more power-efficient...

2. Have you noticed that the current OpenGL version is 4.5? Then... why Apple's OSX barely supports 3.2? Also, they set the max vertex count to 150k and index count to only 1M. It's almost impossible to render dense meshes efficiently with those limits!

Also, I will never understand why OpenGL's group decided to use source-coded shaders. It's much better to use precompiled ones like Direct3D or OpenCL's SPIR does, separating the compiling from linking and allowing to use virtual functions/interfaces so the user can inject closed-code functions there.

3. Why C++'s ABI is not standarized yet? If you write a plug-in or component system it's a fucking nightmare to make it compatible across different compilers. Seriously, is it so difficult to meet the major ISVs there ( Oracle, IBM, Microsoft, GNU, Apple LLVM, Intel, etc... ) and to decide a  standard C++ ABI based on Itanium64 or LLVM ?

4. Why Android is still not massively introduced in the desktop computers?
There is a small project called , but lacks lots of hardware support. I simply cannot understand why Google does not bump that !

5.We like the start button and XP's style! Is that so hard to understand, Microsoft? A desktop PC is NOT a touch screen, it's not a mobile phone and neither a tablet. We use mouse and keyboard ! In fact, the first two things the people do after installing Windows 8 are:

1. Install any of the available start button hacks ( Pokki, IObit, etc... )

2. Remove all the damm metro apps with these Powershell's commands:

Get-AppxPackage -AllUsers | Remove-AppxPackage
Get-AppXProvisionedPackage -online | Remove-AppxProvisionedPackage –online
