[x3d-public] X3DOM Documentation: Gamma Correction

[Patrick Dähne]

Hi Michalis,

> 7. Castle Game Engine by default applies gamma correction on PhysicalMaterial, and *does not* apply gamma correction on Material or UnlitMaterial.

Ok. Let’s say you have something like that:

Shape {
  appearance Appearance {
    material Material {
      texture DEF tex ImageTexture {
        url "foo.png"
      }
    }
  }
  geometry Box {}
}

Shape {
  appearance Appearance {
    material PhysicalMaterial {
      baseTexture USE tex
    }
  }
  geometry Box {}
}

What’s the internal OpenGL texture format of the ImageTexture?  GL_RGB or  GL_SRGB?

Bye,

Patrick
