3D-Tech News Around The Web / AMD Radeon R9 290X: Mantle vs Direct3D 11 in Several Games

In this series we’ll be looking at the benefits of AMD’s Mantle API over Microsoft’s DirectX 11.
...
This is a five part series; in part 1 we’ll be looking at the performance of AMD’s flagship single GPU the Radeon R9 290X.
....

Clearly Mantle offers current Radeon R9 290X owners an easy way to boost the performance of their hardware for free. That’s good news for those users that purchased their hardware with the belief that Mantle enabled games would eventually come this far into the mainstream. It’s also good news for AMD and its partners in the video game industry who have stacked up quite a bit of support for this API.

English forum / GLSL compiler: NVIDIA vs AMD vs Intel (02)
« Last post by JeGX on November 16, 2014, 12:11:28 PM »
In a recent shader, I wrote this line:
Code: [Select]
float lum =  T * vec4(0.21, 0.72, 0.07, 0);

where T is a vec4.

This line works perfectly on NVIDIA GLSL compiler but generates an error on AMD compiler:
Quote
ERROR: 0:78: '=' :  cannot convert from '4-component vector of float' to 'float' 

The error produced by AMD GLSL compiler is correct and NVIDIA should do the same thing.  Weirdly, the shader works properly and the rendering was  the one expected on NVIDIA GPUs.

The right code is:
Code: [Select]
float lum =  dot(T, vec4(0.21, 0.72, 0.07, 0));

which is ok on all graphics hardware!

Hello everybody,
My name is Antonino Perricone, I am a 3D programmer since the year 2000.
I just write the explanation of 2 algorithms that every 3D programmer must know, I think.
You can read it in: http://aperricone.altervista.org/algorithms/
They have an animated area where the algorithm is implemented.
I'd like to know your opinion.
Regards to all,
Perry
