RenderDoc documentationrenderdoc.org原理分析主要还是python部分的原理怎么调用RenderDoc接口官网虽然有解析和例子但是并不完全导出图片的那个例子居然是导出output的图片。就是fragment Shader return出去的那个完全没找到input的图片我都是自己试出来的。其实导出顶点CSV跟导出图片都用到个这个函数controller.GetPipelineState()从这个pipeline的state里面获取就是对应RenderDoc里面的这个面板然后用这个函数state.GetReadOnlyResources(renderdoc.ShaderStage.Fragment)这个里面就有所有的图片的resourceId,可以写个循环保存所有的图片。texsave rd.TextureSave()texsave.resourceId resourceIdif texsave.resourceId rd.ResourceId.Null():return Falsefilename str(int(texsave.resourceId))texsave.mip 0texsave.slice.sliceIndex 0texsave.alpha rd.AlphaMapping.Preservetexsave.destType rd.FileType.PNGif not os.path.exists({0}/{1}.format(folderName,eventId)):os.makedirs({0}/{1}.format(folderName,eventId))outTexPath {0}/{1}/{2}.png.format(folderName,eventId,filename)controller.SaveTexture(texsave, outTexPath)同样的vertex也是这么获取获取vertex index的resourceId,跟vertex自身的resourceId。ib.state.GetIBuffer()vbs.state.GetVBuffers()....something...meshInput.indexResourceId ib.resourceId # vertex index的resourceIdmeshInput.vertexResourceId vbs[attr.vertexBuffer].resourceId # vertex自身的resourceId然后根据resourceId去BufferData里面去得到vertexcontroller.GetBufferData(meshInput.indexResourceId, meshInput.indexByteOffset, 0)源码只给出python源码C#源码可以参考这里RenderDocMeshParserForUnitygithub.comimport sysimport csvfolderName C:/Users/Administrator/Desktop/capMesh1startIndex 475endIndex 759isPrint False# Import renderdoc if not already imported (e.g. in the UI)if renderdoc not in sys.modules and _renderdoc not in sys.modules:import renderdoc# Alias renderdoc for legibilityrd renderdoc# Well need the struct data to read out of bytes objectsimport structimport os# We base our data on a MeshFormat, but we add some propertiesclass MeshData(rd.MeshFormat):indexOffset 0name def pySaveTexture(resourceId,eventId,controller):texsave rd.TextureSave()texsave.resourceId resourceIdif texsave.resourceId rd.ResourceId.Null():return Falsefilename str(int(texsave.resourceId))# texsave.alpha rd.AlphaMapping.BlendToCheckerboard# Most formats can only display a single image per file, so we select the# first mip and first slicetexsave.mip 0texsave.slice.sliceIndex 0texsave.alpha rd.AlphaMapping.Preservetexsave.destType rd.FileType.PNGif not os.path.exists({0}/{1}.format(folderName,eventId)):os.makedirs({0}/{1}.format(folderName,eventId))outTexPath {0}/{1}/{2}.png.format(folderName,eventId,filename)controller.SaveTexture(texsave, outTexPath)print(保存图片{0}.format(outTexPath))return Truedef findIndexDrawLoop(d,index):ret Noneif d.eventId index:return dfor c in d.children:ret findIndexDrawLoop(c,index)if ret:return retreturn ret# Recursively search for the drawcall with the most verticesdef findIndexDraw(index,controller):ret Nonefor d in controller.GetDrawcalls():if d.eventId index:ret dreturn retfor c in d.children:ret findIndexDrawLoop(c,index)if ret:return retreturn ret# Unpack a tuple of the given format, from the datadef unpackData(fmt, data):if isPrint:print(888)# We dont handle special formats -
