Motion Blurr

[Marco Hernandez]

Hello, I wanna know how to invoke a motion Blurr effect to the screen on any time and duration. ¿Any one have any Idea of how to do that?

Here are a list of example games and where a similar effect occurrs.
Grand Theft Auto 3 - When It rains
Chaos Legion - When you make a critical hit on an enemy
Max Payne 2 - When you reload you gun in bullet time mode
Doom3 - When you get the Beserk Powerup Item

Search the forum, and notice that blur takes only one s.

Dont listen to anyone that says RTFM.

an idea how to do it:

1. get the current view and project it on a texture
2. display that texture several times with different alpha values on the screen and with a little offset per picture

but that would require render-to-texture, which irrlicht does not support at the moment (but niko is working on it i guess)

Would it be possible with a vertex shader where a direction vector is pased in and the vertices are 'streaked' backwards with decreasing alpha values.

[Robomaniac]

Its possible with pixel shaders and render to texture for a post processing pass

Allright then...

¿Where can I find a Clear and Direct Explenation of Shaders? I thought shaders only apply to Materials, not to the screen. ¿Am I missing something?
