멀티 샘플링 프레임 버퍼 불완전하고 내가

Question

이 내 코드는 "표면"만들 이유를 알고하지 않습니다

[LOG]: Created Texture Parameters: NoError
[LOG]: Created Image: NoError
[LOG]: Framebuffer status: FramebufferIncompleteAttachment

: 나는 1보다 큰 멀티 샘플링을 사용할 때마다 이제

private void Create(int width, int height, SurfaceFormat format) 
{ 
    bool multisample = format.Multisample > 1; 
    if (multisample) 
     GL.Enable(EnableCap.Multisample); 
    int samples = Math.Max(1, Math.Min(format.Multisample, 4)); 
    TextureTarget target = multisample ? TextureTarget.Texture2DMultisample : TextureTarget.Texture2D; 
    Width = width; 
    Height = height; 
    textureHandle = GL.GenTexture(); 
    //bind texture 

    GL.BindTexture(target, textureHandle); 
    Log.Error("Bound Texture: " + GL.GetError()); 
    if (!multisample) 
    { 
     GL.TexParameter(target, TextureParameterName.TextureMinFilter, (int)TextureMinFilter.Nearest); 
     GL.TexParameter(target, TextureParameterName.TextureMagFilter, (int)TextureMagFilter.Nearest); 
     GL.TexParameter(target, TextureParameterName.TextureWrapS, (int)format.WrapMode); 
     GL.TexParameter(target, TextureParameterName.TextureWrapT, (int)format.WrapMode); 
    } 

    Log.Debug("Created Texture Parameters: " + GL.GetError()); 
    if (format.Multisample < 2) 
     GL.TexImage2D(target, 0, format.InternalFormat, Width, Height, 0, format.PixelFormat, format.SourceType, format.Pixels); 
    else 
     GL.TexImage2DMultisample(TextureTargetMultisample.Texture2DMultisample, samples, format.InternalFormat, Width, Height, false); 
    Log.Debug("Created Image: " + GL.GetError()); 
    //unbind texture 
    GL.BindTexture(target, 0); 
    //create depthbuffer 
    if (format.DepthBuffer) 
    { 
     GL.GenRenderbuffers(1, out dbHandle); 
     GL.BindRenderbuffer(RenderbufferTarget.RenderbufferExt, dbHandle); 

     if(multisample) 
      GL.RenderbufferStorageMultisample(RenderbufferTarget.RenderbufferExt, samples, RenderbufferStorage.Rgba8, Width, Height); 
     else 
      GL.RenderbufferStorage(RenderbufferTarget.RenderbufferExt, RenderbufferStorage.DepthComponent24, Width, Height); 
    } 

    //create fbo 
    fboHandle = GL.GenFramebuffer(); 
    GL.BindFramebuffer(FramebufferTarget.FramebufferExt, fboHandle); 
    GL.FramebufferTexture2D(FramebufferTarget.FramebufferExt, FramebufferAttachment.ColorAttachment0Ext, target, textureHandle, 0); 

    if(format.DepthBuffer) 
     GL.FramebufferRenderbuffer(FramebufferTarget.FramebufferExt, FramebufferAttachment.DepthAttachmentExt, RenderbufferTarget.RenderbufferExt, dbHandle); 
    Log.Debug("Framebuffer status: " + GL.CheckFramebufferStatus(FramebufferTarget.FramebufferExt)); 
    Log.Debug("Created Framebuffer: " + GL.GetError()); 
    GL.BindFramebuffer(FramebufferTarget.FramebufferExt, 0); 

} 

를, 나는 오류가 발생합니다 MS가 2 미만인 경우, 모든 것이 잘 작동

... 당신은 여기 renderbuffer에 대한 잘못된 형식을 사용하고

Answer 1

:

,

GL.RenderbufferStorageMultisample(RenderbufferTarget.RenderbufferExt, samples, 
     RenderbufferStorage.Rgba8, Width, Height); 

나중에이 버퍼를 깊이 부착으로 사용하십시오. GL_RGBA8은 깊이 첨부의 유효한 형식이 아닙니다. 깊이 첨부의 일반적인 형식은 GL_DEPTH_COMPONENT16 및 GL_DEPTH_COMPONENT24입니다. 전화를 다음으로 변경해야합니다.

GL.RenderbufferStorageMultisample(RenderbufferTarget.RenderbufferExt, samples, 
     RenderbufferStorage.DepthComponent24, Width, Height);
