Hi Robert, the 200ms seem to be very rare spikes and the median draw time for an animation step for the bigger model is 40ms and for the smaller model 13ms. > How much dynamic data needs to be transferred when it's updated? The bigger model has 110MB of coordinates and normals to be

[osg-users] Optimize data transfer to GPU

2021-06-23 Thread Daniel Trstenjak
Hi, for an animation we have to change the coordinates per frame. The draw time for the model without a coordinate change is about 3ms. With the coordinate change it can go up to 200ms. With a model of about half the size I see pretty much the same draw time without the coordinate change. With

Re: [osg-users] Best way to debug detected OpenGL error 'invalid value' at top of State::apply(StateSet*)

2020-06-03 Thread Daniel Trstenjak
Hi Erik, > My question is: how can I find out what the underlying problem is? What is > the 'invalid value'? > Where is it coming from? take a look at the GL_KHR_debug and GL_ARB_debug_output extensions. They add some checking to OpenGL state changes and report errors. Greetings, Daniel --
