I have been hosting a program, started in March of 2015, called “Innovation Think” with the intent to get people exposed to technology that stimulates innovation either directly or through the exercising of the creative mind.

《勇者大冒险》游戏中的Havok物理、破坏和布料引擎

由像素Pixel开发的《勇者大冒险》是一款超好玩的冒险网游,今天在这里给大家介绍一下《勇者大冒险》游戏中的Havok物理、破坏和布料引擎。

当我们进入 《勇者大冒险》游戏中,突然发现原来置身在这千年古墓中的我们可以大搞破坏?这是一种什么感觉,那还用说吗,当然是这种feel倍儿爽啦!

   埃及古墓里的壁画?突突了它!

    欧洲古迹的罗马柱?突突了它!

   如潮水般涌来的怪物?突突了它!

    这种真实的打击感以及身临其境的高度紧张使得我们在游戏中彻底变成了“熊孩子”,价值千万的古董毁在我们手里,一切面容可憎的怪物都成了战五渣,想想就有点儿小激动呢!

kernel “vector + vector”, return the right result only if vector's length is a multiple of 64

I'm new to OpenCL. And I'm trying to run a kernel “vector + vector”, I could get the right result only if vector's length equals  a multiple of 64. For example, I will get the output below when I set the length to 16. 

Compiling OpenCL 2.0 atomics

Hi,

I am trying to compile a simple kernel using OpenCL 2.0 atomics using exactly the device, driver, and kernel described in:

https://software.intel.com/en-us/forums/topic/556904

However, I cannot even get the kernel to compile, as it does not seem to recognize the atomic types and functions. My error log (along with some environment info) is:

  • change image format of image object in opencl

    I have written a small code to create an image object in opencl as below:

    img_fmt.image_channel_order = CL_R;
    img_fmt.image_channel_data_type = CL_UNSIGNED_INT8;      
    memobj_in_luma = clCreateImage2D(p->context, CL_MEM_READ_ONLY, &img_fmt, p->width, p->height, 0, NULL, &ret);

    After creating this object I want to change the image format to CL_RGBA. Is there any way to do this?

    HD4400 bitwise and operation on uchar2 data

    Hello,
    we are seeing different results when implementing "bitwise and" operation in OpenCL kernel working on uchar2 data. The OpenCL kernel code like this:
    uchar2 val1;
    uchar2 val2;
    uchar3 res;
    res = val1 & val2;

    produce wrong results, while code like below:

    res = (uchar2)(val1.x & val2.x, val1.y & val2.y)
    produce correct result.

    BTW, the same behaviour detected for bitwise or/xor and uchar3/4 data, although attached test case was prepared only for "bitwise and" on uchar2 data.
