Geeks3D's GPU Tools / Re: Msi kombustor test3d= ID needed
« on: July 05, 2015, 06:25:05 PM »
The ID of Triangle of Death demo is 2001.

There is no command line param for the number of particles in the fractal flame test. Maybe in a next release.

Havok®, a leading provider of AAA game development technology, extends congratulations to all of the nominees of Game Critics Awards for “Best of E3 2015,” which includes several of Havok’s developer partners.  The nominees pushed the limits of realism to create remarkable AAA game experiences.  Some of these great titles range from Bethesda Softworks’ wildly ambitious and gigantic open-world role-playing game,  Fallout 4, to the deeply compelling narrative and intense adventure of Sony and Naughty Dog’s  Uncharted 4: A Thief’s End, to the visually spectacular and blistering firefights of  Star Wars Battlefront. Havok’s cross-platform suite of technology helps create some of the most ambitious AAA games that leverage the new hardware, and this same technology continues to service future projects that will become milestone titles for years to come.

Havok congratulates the following AAA projects powered by Havok technology that are among the titles nominated by the Best of E3 2015 awards:

·          Star Wars Battlefront - Electronic Arts

·          Dark Souls III – BANDAI NAMCO Entertainment

·          Fallout 4 - Bethesda Softworks

·          Halo 5: Guardians - Microsoft Studios

·          Horizon: Zero Dawn - Sony Computer Entertainment

·          Just Cause 3 - Square Enix

·          Need for Speed - Electronic Arts

·          No Man's Sky - Hello Games

·          The Last Guardian - Sony Computer Entertainment

·          Tom Clancy's Rainbow Six Siege - Ubisoft

·          Tom Clancy's The Division - Ubisoft

·          Uncharted 4: A Thief's End - Sony Computer Entertainment

Here is a very simple slideshow demo that displays several images, each image being displayed during 1.0 second (the duration can be changed in the code):

Could you paste the pixel shader ?

I coded a simple slideshow demo :

I hope that demo will help you with your transition effects.

Don't know how to get the value "p" for the vertex shader (so i used the VS that comes with GLSL Hacker)

There is no standard name for the vertex shader inputs but usually there is always the position. In your case:
Code: [Select]
attribute vec3 p;void main(){gl_Position=vec4(p,1.);}

replace  "attribute vec3 p" by "in vec4 gxl3d_Position" :
Code: [Select]
#version 150
in vec4 gxl3d_Position;
void main()
  gl_Position = gxl3d_Position;

- Only use an Atomic when necessary, check if a volatile will meet your needs first
- Keep classes with multicore access segmented by cache lines to eliminate False Sharing
- Local variables are preferred over sharing data outside of the thread

3D-Tech News Around The Web / Cache And How To Work For It
« on: June 18, 2015, 02:19:08 PM »
The Cache is always trying to guess what memory you’ll need to have before you request it, this prediction is called Cache Prefetching. This is why when working on an array it’s best to go through in sequential order instead of randomly jumping through, as the Cache Prefetcher will be able to guess what you’re using and have it ready before you need it. Cache loads things in groups of 64 bytes. The size is CPU-dependant and can be checked under your CPU’s specification under Cache Line size, although it’s typically 64 bytes. This means that if you have an array of integers and you grab 1 of those integers, the cache has also grabbed the Cache Line that it sits on. Grabbing the next integer stored next to it will be a Cache Hit and subsequently extremely fast. The alignment of the Cache Line will always be a multiple of the Cache Line's size, meaning that if you fetch memory at 0x00 (0) then what will be cached is everything between 0x00 (0) and 0x40 (64) and if you fetch something at 0x4F (79) then you’ll get everything between 0x40 (64) and 0x80 (128).

The only limitation is that you won't be able to use Python in your demos. That's all. All features are available in Lua and Python so the Python plugin is not mandatory.

Now if you want to play with Python, you have to install the latest Python 2.7 64-bit :


I have to look at this issue in a near future...

I'll try to post a demo asap that displays several images that should help you.

In the horror genre, gore and guts are commonplace. And the folks at Tripwire Interactive are using our technology to take the gore in their new horror survival game to a new level. In Killing Floor 2, you must fight your way through waves of mutated specimens, called Zeds. The longer you fight, the messier things get.

The three foundations of the game’s initial design mantra were “Bullets, Blades and Blood.” And that lead to the creation of the M.E.A.T. (massive evisceration and trauma) system to depict dynamic gore, blood splatter and detailed graphic violence. To get the M.E.A.T. just right, Tripwire made Killing Floor 2 the first game to use our NVIDIA PhysX FleX technology for soft tissue and fluid interaction. That’s geek for guts and blood splatter.

3D-Tech News Around The Web / OS X Metal - Raw Notes
« on: June 15, 2015, 11:24:29 AM »
Metal for desktop has instancing, sane constant buffers, texture barrier, occlusion query, and draw-indirect. It looks like it does not have transform feedback, geometry shaders or tessellation. (The docs do mention outputting vertices to a buffer with a nil fragment function, but I don't see a way to specify the output buffer for vertex transform. I also don't see any function attach points for geometry shaders or tessellation shaders.)


3D-Tech News Around The Web / AMD Radeon R9 Fury X latest news
« on: June 15, 2015, 11:14:47 AM »
Latest news about AMD Radeon Fury (Fiji GPU).



The board has 2 x 8-pin power connectors that allows the card to draw up to 375W.


Scores at 3DMark FireStrike Extreme (P1440 ) and Ultra (P2160):

We present a technique for synthesizing the effects of skin microstructure deformation by anisotropically convolving a highresolution displacement map to match normal distribution changes in measured skin samples. We use a 10-micron resolution scanning technique to measure several in vivo skin samples as they are stretched and compressed in different directions, quantifying how stretching smooths the skin and compression makes it rougher. We tabulate the resulting surface normal distributions, and show that convolving a neutral skin microstructure displacement map with blurring and sharpening filters can mimic normal distribution changes and microstructure deformations. We implement the spatially-varying displacement map filtering on the GPU to interactively render the effects of dynamic microgeometry on animated faces obtained from high-resolution facial scans.
