让RenderDoc批量导出纹理

2020/10 03 18:10

RenderDoc导出纹理时只能一张张导出,非常麻烦,改一下RenderDoc,效果如下

一、qrenderdoc\Windows\TextureViewer.ui中追加2个按钮

<item>
     <widget class="QToolButton" name="saveTex">
      <property name="toolTip">
       <string>Save selected Texture</string>
      </property>
      <property name="text">
       <string/>
      </property>
      <property name="icon">
       <iconset resource="../Resources/resources.qrc">
        <normaloff>:/save.png</normaloff>:/save.png</iconset>
      </property>
      <property name="autoRaise">
       <bool>true</bool>
      </property>
     </widget>
    </item>
<item>

// 追加以下代码

    <widget class="QToolButton" name="saveTexs">
        <property name="toolTip">
            <string>Batch Save Textures => d:\\capture\\ </string>
        </property>
        <property name="text">
            <string/>
        </property>
        <property name="icon">
            <iconset resource="../Resources/resources.qrc">
                <normaloff>:/save2.png</normaloff>:/save2.png</iconset>
        </property>
        <property name="autoRaise">
            <bool>true</bool>
        </property>
    </widget>
    </item>
    <item>
     <widget class="QToolButton" name="saveAllTex">
      <property name="toolTip">
       <string>Save all Textures => d:\\capture\\ </string>
      </property>
      <property name="text">
       <string/>
      </property>
      <property name="icon">
       <iconset resource="../Resources/resources.qrc">
        <normaloff>:/save3.png</normaloff>:/save3.png</iconset>
      </property>
      <property name="autoRaise">
       <bool>true</bool>
      </property>
     </widget>
    </item>
    <item>

二、qrenderdoc/Code/Resources.h中追加2个图标

  RESOURCE_DEF(save, "save.png")                                        \
  RESOURCE_DEF(save2, "save2.png")                                      \
  RESOURCE_DEF(save3, "save3.png")                                      \

三、qrenderdoc/Resources/目录中添加几个新图标,save2.png, save2@2x.png, save3.png, save3@2x.png

四、qrenderdoc/Resources/resources.qrc中追加2个图标

        <file>save.png</file>
        <file>save2.png</file>
        <file>save3.png</file>

五、在qrenderdoc/Windows/TextureViewer.cpp中追加代码


static TextureSave tmpSaveCfg;

void TextureViewer::SaveStageResourcePreviews(ShaderStage stage,
                                              const rdcarray<ShaderResource> &resourceDetails,
                                              const rdcarray<Bindpoint> &mapping,
                                              rdcarray<BoundResourceArray> &ResList,
                                              int &prevIndex, bool copy,
                                              bool rw, const QString& savePath)
{
  for(int idx=0; idx < mapping.count(); idx++)
  {
    const Bindpoint &key = mapping[idx];

    const rdcarray<BoundResource> *resArray = NULL;
    uint32_t dynamicallyUsedResCount = 1;
    int32_t firstIndex = 0;

    int residx = ResList.indexOf(key);
    if(residx >= 0)
    {
      resArray = &ResList[residx].resources;
      dynamicallyUsedResCount = ResList[residx].dynamicallyUsedCount;
      firstIndex = ResList[residx].firstIndex;
    }

    int arrayLen = resArray != NULL ? resArray->count() : 1;

    const bool collapseArray = arrayLen > 8 && (dynamicallyUsedResCount > 20 || m_ShowUnused);

    for(int i = 0; i < arrayLen; i++)
    {
      int arrayIdx = firstIndex + i;

      if(resArray && i >= resArray->count())
        break;

      if(resArray && !resArray->at(i).dynamicallyUsed)
        continue;

      BoundResource res = {};

      if(resArray)
        res = resArray->at(i);

      Following follow(*this, rw ? FollowType::ReadWrite : FollowType::ReadOnly, stage, idx,
                       arrayIdx);

      // show if it's referenced by the shader - regardless of empty or not
      bool show = key.used || copy;

      // it's bound, but not referenced, and we have "show disabled"
      show = show || (m_ShowUnused && res.resourceId != ResourceId());

      // it's empty, and we have "show empty"
      show = show || (m_ShowEmpty && res.resourceId == ResourceId());

      // it's the one we're following
      show = show || (follow == m_Following);

      if(!show)
      {
        continue;
      }
      
      tmpSaveCfg.resourceId = res.resourceId;
      tmpSaveCfg.destType = FileType::TGA;
      tmpSaveCfg.channelExtract = -1;
      tmpSaveCfg.alphaCol = FloatVector(0, 0, 0, 0);

      uint64_t currId = *((uint64_t*)&res.resourceId);
      QString fn = QString(tr("%1\\%2.tga")).arg(savePath).arg(currId);

      bool ret = false;
      m_Ctx.Replay().BlockInvoke([this, &ret, fn](IReplayController *r) 
      {
        ret = r->SaveTexture(tmpSaveCfg, fn.toUtf8().data());
      });
    }
  }
}

static uint captureBatch = 0;

void TextureViewer::on_saveTexs_clicked()
{
  int outIndex = 0;
  int inIndex = 0;

  bool copy = false, clear = false, compute = false;
  Following::GetDrawContext(m_Ctx, copy, clear, compute);

  ShaderStage stages[] = {ShaderStage::Vertex, ShaderStage::Hull, ShaderStage::Domain,
                          ShaderStage::Geometry, ShaderStage::Pixel};

  int count = 5;

  if(compute)
  {
    stages[0] = ShaderStage::Compute;
    count = 1;
  }

  const rdcarray<ShaderResource> empty;

  QString currDir;
  for(int i = 0; i < 2048; ++i)
  {
    ++captureBatch;
    currDir = QString(tr("d:\\capture\\cap_%1")).arg(captureBatch);
    QDir dir(currDir);
    if(dir.exists())
    {
      continue;
    }

    dir.mkpath(currDir);
    break;
  }

  // display resources used for all stages
  for(int i = 0; i < count; i++)
  {
    ShaderStage stage = stages[i];

    m_ReadWriteResources[(uint32_t)stage] =
        Following::GetReadWriteResources(m_Ctx, stage, !m_ShowUnused);
    m_ReadOnlyResources[(uint32_t)stage] =
        Following::GetReadOnlyResources(m_Ctx, stage, !m_ShowUnused);

    const ShaderReflection *details = Following::GetReflection(m_Ctx, stage);
    const ShaderBindpointMapping &mapping = Following::GetMapping(m_Ctx, stage);

    SaveStageResourcePreviews(stage, details != NULL ? details->readOnlyResources : empty,
                              mapping.readOnlyResources, m_ReadOnlyResources[(uint32_t)stage],
                              inIndex, copy, false, currDir);
  }
}

void TextureViewer::on_saveAllTex_clicked()
{
  for(const TextureDescription &tex : m_Ctx.GetTextures())
  {
    tmpSaveCfg.resourceId = tex.resourceId;
    tmpSaveCfg.destType = FileType::TGA;
    tmpSaveCfg.channelExtract = -1;
    tmpSaveCfg.alphaCol = FloatVector(0, 0, 0, 0);

    QString fn;
    fn.sprintf("d:\\capture\\%d.tga", tex.resourceId);
    
    QFileInfo qi(fn);
    QDir dir(qi.absoluteDir());
    if (!dir.exists())
    {
      dir.makeAbsolute();
    }

    bool ret = false;
    m_Ctx.Replay().BlockInvoke([this, &ret, fn](IReplayController *r) {
      ret = r->SaveTexture(tmpSaveCfg, fn.toUtf8().data());
    });
  }
}

然后头文件中追加

void on_saveTexs_clicked();
void on_saveAllTex_clicked();

void SaveStageResourcePreviews(ShaderStage stage, const rdcarray &resourceDetails, const rdcarray &mapping, rdcarray &ResList, int &prevIndex, bool copy, bool rw, const QString& savePath);

然后构建后,点黄色按钮可批量导出纹理到 d:\capture\cap_XXX 目录中
点紫色按钮可导出所有纹理到 d:\capture\目录中
也不会弹出对话框了,实乃挖图利器

导出Mesh可以参考这个
