Problem with CartoonEdgeFilter

Troubleshooting graphics
1

Hello. I’m just start plaing with jme. I’m not experienced whith developing 3d applications and with shaders especially.

I’ve created simple scene and try use CartoonEdgeFilter and got some artefacts. Looks like shader program dont take into account the distance between planes, only normals differense.



Is it possible to fix this artefacts?

Sorry for my english and mb terminolgy issues :slight_smile:

Mhh strange CartoonEdgeFilter does not use only normals, it uses depth too.



Could you provide a test case?

O, thanks for a fast answer and for giving me a way to find solution :slight_smile:

I’ve tried to make scene simpler. Then i try to play whith setDepthThreshold and DepthSensitivity, and i find solutuion. The edges drawing is based on camera position (didn’t know/understand this). Now i’m going to find perfect dependency between sensetivity/threshol/campostion to take an effect i want.

Anywhere - there is test case. Uncomment lines 36, 37 to take effect.
