Image blur

[k_iwan]

If I'm not mistaken...You need to create a custom renderer plug ins for Vizard to do this, or by using OpenGL Shader Language.

Since I'm only a 3d modeler, I don't have the head show you how this is done :P

I have a sample script that performs a uniform blur over the entire screen. Is this what you are looking for? The script only works with the latest version of Vizard 3.0 and requires a decent graphics card that supports shaders. Are you able to use 3.0? Also, do you need this effect to work in stereo, or just mono?

Yes, we are using 3.0. I'm not sure if we have a decent graphics card, but I'd certainly like to try it. We only need mono.
Thanks!

I've attached a zip file which contains a script testBlur.py. This script depends on the included vizblur.py module. This example will only run on Vizard 3.00.1723 and above. You will need a graphics card that supports shaders.

Also, in the future please post Vizard 3.0 related questions in the Vizard 3.0 forum.

Hi,

I tried it, but did not run.. seems like something is missing?!?

a "vizblur.pyc" was created in the same folder after executing this demo.

I'll try again tonight. (I'm running on latest beta version... VizardR3 b3)... next time I will post under Vizard 3 forum.

It seems your graphics card doesn't support the latest version of GLSL. You might try updating your driver if you already haven't. I'll try to make the shader compatible with older drivers as well.

Hi

I thought so... My graphics card at home is ATI9600Pro (I wondered why I picked ATI in the first place anyway, I always have problem with overheating)
I doubt by updating to the latest driver would solve this problem but I will give it a try.

I will try again with Uni's computers.

I had the same problem. I'll try upgrading my driver.

Also, I posted here because I was hoping to find a solution that worked under Vizard 2.5 as well. The main project we need it for is 3.0, so it's OK if it doesn't work in 2.5.

We're going to buy a new machine to run on. What do we need to look for in a graphics card to get this to work?
