DX11 Render FPS Weapon in World or View Space ?

Recommended Posts

Endemoniada    430

Hi guys,

Do you think I should render my first-person hand/weapon in world space or view space, is there a preferred method ? I got it to work in view space but now I have to do all the lighting in view space too, that's not much of a problem but I've been doing it in world space.

I think I would rather do it in world space unless there is a good reason not too. I haven't been able to get that working though.

Any help would be appreciated, especially getting it to work in world space.

Thanks.

For the sake of clarity and maintenance, I would keep all my outputs in shaders in the same space (either viewspace or worldspace), no matter if it's first person or not.

But you will probably want to keep camera space items (like first person, weapons) in camera local space (viewspace) up until you want to draw them for precision issues. Otherwise you might end up with shaky hands and weapons due to floating point precisions.

      Hi! I am trying to implement simple SSAO postprocess. The main source of my knowledge on this topic is that awesome tutorial.
      But unfortunately something doesn't work... And after a few long hours I need some help. Here is my hlsl shader:
      float3 randVec = _noise * 2.0f - 1.0f; // noise: vec: {[0;1], [0;1], 0} float3 tangent = normalize(randVec - normalVS * dot(randVec, normalVS)); float3 bitangent = cross(tangent, normalVS); float3x3 TBN = float3x3(tangent, bitangent, normalVS); float occlusion = 0.0; for (int i = 0; i < kernelSize; ++i) { float3 samplePos = samples[i].xyz; // samples: {[-1;1], [-1;1], [0;1]} samplePos = mul(samplePos, TBN); samplePos = positionVS.xyz + samplePos * ssaoRadius; float4 offset = float4(samplePos, 1.0f); offset = mul(offset, projectionMatrix); offset.xy /= offset.w; offset.y = -offset.y; offset.xy = offset.xy * 0.5f + 0.5f; float sampleDepth = tex_4.Sample(textureSampler, offset.xy).a; sampleDepth = vsPosFromDepth(sampleDepth, input.uv).z; const float threshold = 0.025f; float rangeCheck = abs(positionVS.z - sampleDepth) < ssaoRadius ? 1.0 : 0.0; occlusion += (sampleDepth <= samplePos.z + threshold ? 1.0 : 0.0) * rangeCheck; } occlusion = saturate(1 - (occlusion / kernelSize)); And current result: http://imgur.com/UX2X1fc
      I will really appreciate for any advice!

       I'm trying to code Rayleigh part of Nishita's model (Display Method of the Sky Color Taking into Account Multiple Scattering). I get black screen no colors. Can anyone find the issue for me?

      I made my obj parser
      and It also calculate tagent space for normalmap.
      it seems calculation is wrong..
      any good suggestion for this?
      I can't upload my pics so I link my question.
      https://gamedev.stackexchange.com/questions/147199/how-to-debug-calculating-tangent-space
      and I uploaded my code here

      Hi guys, 

      I dont know if this is the right section, but I did not know where to post this. 
      I am implementing a day night cycle on my game engine and I was wondering if there was a nice way to interpolate properly between warm colors, such as orange (sunset) and dark blue (night) color. I am using HSL format.
      Thank  you.

      I am aiming to learn Windows Forms with the purpose of creating some game-related tools, but since I know absolutely nothing about Windows Forms yet, I wonder:
      Is it possible to render a Direct3D 11 viewport inside a Windows Form Application? I see a lot of game editors that have a region of the window reserved for displaying and manipulating a 3D or 2D scene. That's what I am aiming for.
      Otherwise, would you suggest another library to create a GUI for game-related tools?
       
      EDIT:
      I've found a tutorial here in gamedev that shows a solution:
      Though it's for D3D9, I'm not sure if it would work for D3D11?
