Hi everyone, I've attached a screenshot which shows a series of white dots.

These are flickering constantly when I move and rotate my 3d models.

Any ideas what it could be and how I could solve it ?

Its a very simple setup with Jit.gl.model to jit.gl.mesh so nothing fancy.

unfortunately, jitter handles this less elegantly than, say, vvvv, which does this much less. There are some solutions described in the wiki, but more often than not it can be solved by careful filtering of your data.

Thanks Wetterberg ! As I'm still pretty much a Jitter noob can you give me any terms,tips or pointers on how to solve this. ?

How would I increase the precision of the Z-buffer in Jitter?

At least the enemy has a name now ! ;-)


The strange part is this, it's all one model, no extra textures are being loaded onto the model. Could it just have to do with the refresh rate of the buffer for calculating the vertex positions ?

After checking around some more I discovered that increasing the near clip number can reduce quite a lot of the flickering, not all of it but it is an improvement.

The default setting of jit.gl.render is near_clip 0.1 and far_clip is 100

I've set them to near_clip 0.6 (sometimes 1.0) and far_clip 50

If objects get too close to the camera then faces vanish.

Any other suggestions are more than welcome as I'm still confused by this occurring with only one model not the usual issue of multiple planes/geometry overlapping.

increasing the @near_clip is a good idea.

you might also try turning on back-face culling (@cull_face 1) on your jit.gl objects.

Are you sure? I mean, a model can easily have overlapping geometry. Can we see the model?
