I am experiencing some issues on the scene drawing and I am not sure about the causes.
I think there are no better explanations for this problem than a couple of images. Please see images below.
Some details: those lines are not fix, they move left and right and they aren’t present all the time. They appear when my object in the scene is moving a lot. I’m using bones to move mesh’s vertexes.
Could anyone help me to understand why this is happening and find a solution?
Thanks in advance!
What OS and 3D API (if any) is in use?
ERRATA CORRIGE: the line IS STATIONARY.
thanks for your kind reply, I was a bit hurrying and I forgot to give important details.
I am using PowerVR SDK OpenGL ES 2.0 on a Beagleboard XM Rev C running Linux Angstrom.
The drawing method I use is the same of the Skinning demo in the TrainingCourse folder of the SDK.
Do other apps, including the SDK apps, all tear in the same location? If so, I suspect that your install is set to use front buffer rendering.
I tried the Skinning, LightMap,ComplexLighting and other demos and I can’t see lines like that.
I tried to insert the eglSwapInterval in the initialization phase but I think I am giving silly values in the 1st parameter (Display). How should I call eglSwapInterval?
In the Skinning example, as said in the comment before the renderScene function:
“eglSwapBuffers() will be performed by PVRShell automatically. PVRShell will also manage important OS events.”
