      How do I fill the gap between sky and terrain? Scaling the terrain or procedural terrain rendering?

    • By Jiraya
      For a 2D game, does using a float2 for position increases performance in any way?
      I know that in the end the vertex shader will have to return a float4 anyway, but does using a float2 decreases the amount of data that will have to be sent from the CPU to the GPU?

      I am feeding in 16 bit unsigned integer data to process in a compute shader and i need to get a standard deviation.
      So I read in a series of samples and push them into float arrays
      float vals1[9], vals2[9], vals3[9], vals4[9]; int x = 0,y=0; for ( x = 0; x < 3; x++) { for (y = 0; y < 3; y++) { vals1[3 * x + y] = (float) (asuint(Input1[threadID.xy + int2(x - 1, y - 1)].x)); vals2[3 * x + y] = (float) (asuint(Input2[threadID.xy + int2(x - 1, y - 1)].x)); vals3[3 * x + y] = (float) (asuint(Input3[threadID.xy + int2(x - 1, y - 1)].x)); vals4[3 * x + y] = (float) (asuint(Input4[threadID.xy + int2(x - 1, y - 1)].x)); } } I can send these values out directly and the data is as expected

                             
      Output1[threadID.xy] = (uint) (vals1[4] ); Output2[threadID.xy] = (uint) (vals2[4] ); Output3[threadID.xy] = (uint) (vals3[4] ); Output4[threadID.xy] = (uint) (vals4[4] ); however if i do anything to that data it is destroyed.
      If i add a
      vals1[4] = vals1[4]/2; 
      or a
      vals1[4] = vals[1]-vals[4];
      the data is gone and everything comes back 0.
       
       
      How does one go about converting a uint to a float and performing operations on it and then converting back to a rounded uint?

      I have been trying to see how the ID3DInclude, and how its methods Open and Close work.
      I would like to add a custom path for the D3DCompile function to search for some of my includes.
      I have not found any working example. Could someone point me on how to implement these functions? I would like D3DCompile to look at a custom C:\Folder path for some of the include files.
      Thanks

      I'm continuing to learn more about terrain rendering, and so far I've managed to load in a heightmap and render it as a tessellated wireframe (following Frank Luna's DX11 book). However, I'm getting some really weird behavior where a large section of the wireframe is being rendered with a yellow color, even though my pixel shader is hard coded to output white. 

      The parts of the mesh that are discolored changes as well, as pictured below (mesh is being clipped by far plane).

      Here is my pixel shader. As mentioned, I simply hard code it to output white:
      float PS(DOUT pin) : SV_Target { return float4(1.0f, 1.0f, 1.0f, 1.0f); } I'm completely lost on what could be causing this, so any help in the right direction would be greatly appreciated. If I can help by providing more information please let me know.

I know this may sound like a very newbish question, but I can't seem to remember the answer and I was wondering, can I write code for DirectX10 using the current DX11 SDK? It's been a while since I have done any 3D programming and when I put it down I was programming in DX10, but it was with the current SDK. Any insight would be appreciated. Thanks.

A question is a question, anyways, yes you should still be able to write DX10 games with the DX11 SDK the static libraries you link against and the headers may be under a different directory in the SDK installation.

Yes, the latest SDK (February 2010) can be used to develop DX9, DX10, and DX11 applications. If you are interested in upgrading to DX11, it uses a similar API structure as DX10 but provides several important updates in functionality (i.e. Compute Shaders and Tessellation). I open sourced my engine if you are interested in some sample code as well (link can be found below...).

Welcome back to 3D!

It's also worth mentioning that DX11 works on DX10 (and DX9) level hardware, so there isn't much reason to go with DX10.

Yes, via 'FeatureLevels' you can select a subset of functionality that corresponds to a particular hardware level. This allows you to use D3D11, and still be able to scale down to D3D9/10 hardware features for a wider audience.

Except that it still needs Vista/Win7 due to the new driver architecture? I'm confused here because to me this suddenly looks like a clean way to support a broad range of GPUs on a modern API. But I can use this only on Vista/Win7, can I?

Correct. If you need to support XP you'll have to provide a DirectX 9 rendering path.
