Saving renderTexture
Hello,
I am trying to save the content of a renderTexture to a file. I basically use code from the examples as listed further down my post. Everytime I call renderTexture.save("test") i get an error message that tells me that there is no data in the image. Code:
* ERROR: Texture does not contain image data, cannot save to file 'test' I also put the texture on a quad to see if there is actually something going wrong, but the desired render is diplayed fine on the quad. Here is my code: Code:
# Create render texture for sending screenshots self.renderTexture = viz.addRenderTexture() # Create render node as camera self.renderNode = viz.addRenderNode(size=(800,600)) # Do not inherit view/projection settings from main window #self.renderNode.setInheritView(False) # Set FOV for renderTexture camera self.renderNode.setFov(self.FOV,800/600.0,0.1,1000.0) # Render to renderTexture feed texture self.renderNode.attachTexture(self.renderTexture) #NOTE: I also tried renderNode.setTexture here, but that didn't work either # Only render once per frame, in case stereo is enabled self.renderNode.setRenderLimit(viz.RENDER_LIMIT_FRAME) #add a texture quad quad = viz.addTexQuad() #add the rendertexture to the texturequad quad.texture( self.renderTexture ) #position the texture quad quad.setPosition(0,1,0) #NOTE: The texture renders fine on the quad self.renderTexture.save("test") #This call fails with above error |

Are you waiting a frame to allow the render node to actually render to the texture? Also, you are not saving the texture to a valid image format. Make sure to add a valid extension to the filename (e.g. test.png, test.jpg, ...).

I scheduled the whole process as a task and used yield waitFrame(1) to make sure that the node has had time to render at least once.
Works well now. Thanks a lot! |
