What is a structure buffer?
A structured buffer is a buffer that contains elements of equal sizes. Use a structure with one or more member types to define an element.
What is SV_DispatchThreadID?
SV_DispatchThreadID is the sum of SV_GroupID * numthreads and GroupThreadID. It varies across the range specified in Dispatch and numthreads. For example if Dispatch(2,2,2) is called on a compute shader with numthreads(3,3,3) SV_DispatchThreadID will have a range of 0.. 5 for each dimension.
What is Groupshared memory?
data via “groupshared” memory. – Pre-load data used by every thread in a group.
What is an IO buffer?
I/O buffering The process of temporarily storing data that is passing between a processor and a peripheral. The usual purpose is to smooth out the difference in rates at which the two devices can handle data. A Dictionary of Computing.
Do compute shaders work on mobile?
Apparently, compute shaders are not fully supported on all mobile devices and how it will work varies from phone to phone. Some android phones have partial support while others might have no support at all.
What is a graphics shader?
A Shader is a user-defined program designed to run on some stage of a graphics processor. Shaders provide the code for certain programmable stages of the rendering pipeline. They can also be used in a slightly more limited form for general, on-GPU computation.
How do I create an array in HLSL?
The most efficient way to create a const array in HLSL?
- Send it to the GPU in a const buffer but the data will never change during the program.
- Declare it as a local array as it is declared now.
- Put the static keyword in front.
- There are const global variables in OpenGL is there such an alternative in D3D?
Why do we need buffered I O?
A buffer is a memory area that stores data being transferred between two devices or between a device and an application. Uses of I/O Buffering : Buffering is done to deal effectively with a speed mismatch between the producer and consumer of the data stream.
Is unbuffered I O more efficient than buffered I O?
Unbuffered output is generally better when you already have large buffers to send — copying to an intermediate buffer will not reduce the number of OS calls further, and introduces additional work.
What are compute shaders good at?
A Compute Shader is a Shader Stage that is used entirely for computing arbitrary information. While it can do rendering, it is generally used for tasks not directly related to drawing triangles and pixels.
Do 2D games use shaders?
For 2D graphics, most of the time you’ll be interested in pixel shaders. Most of those effects mentioned above (including lighting) are usually implemented by pixel shaders.
Why buffering is required?
Need of Buffering : It helps in matching speed between two devices, between which the data is transmitted. For example, a hard disk has to store the file received from the modem. It helps the devices with different data transfer size to get adapted to each other.
Is RAM a buffer?
The buffer memory is mainly located in Random Access Memory (RAM) of a computer. In this area CPU can store its data temporarily, like the data to be forwarded to other slow speed output devices or other secondary storage devices, to enable the computer to execute other processes.
What is the difference between rwstructuredbuffer and byte address buffer?
RWStructuredBuffer is a read/write structured buffer. Atomic functions which implement interlocked operations are allowed on int and uint elements in an RWStructuredBuffer. A byte address buffer is a buffer whose contents are addressable by a byte offset.
What is the use of rwstructuredbuffer variable?
Returns a resource variable. A resource variable can also be passed into any unordered or interlocked operation. RWStructuredBuffer objects can be prefixed with the storage class globallycoherent. This storage class causes memory barriers and syncs to flush data across the entire GPU such that other groups can see writes.
How to bind SRV to id3d11shaderresourceview?
where srv is Microsoft::WRL::ComPtr or ID3D11ShaderResourceView*. Then you bind it using *SetShaderResources.
