Convert framebuffer image to black and white

[royger]

Hello,

I'm interested in rendering some sequences of a game in black and white, and I would like to know if there is any way to apply some kind of "filter" to the framebuffer in order to convert the image to black and white.

Thanks, Roger.

an easy way of making all your textures grey scale (not black and white)

if your using devil to load images
use

  IL.ilConvertImage(IL.IL_LUMINANCE, IL.IL_BYTE);

and

  GL11.glTexImage2D(GL11.GL_TEXTURE_2D, 0, GL11.GL_RGBA, textureWidthSize, textureHeightSize, 
	                    0, GL11.GL_LUMINANCE, GL11.GL_UNSIGNED_BYTE, imageData);

notice the LUMINANCE statements instead of RGBA

hope someone knows a way to make a scene black and white, wouldnt mind one day playing around with the effect

You might have to use a shader to produce a fullscreen black and white effect.
