Example text

Unfortunately when the lit polygon includes a specular highlight, the resulting modulated texture will not look correct since the specular highlight simply changes the brightness of the texture at that point rather than the desired effect of adding in some specular illumination. Some vendors have tried to address this problem with extensions to perform specular lighting after texturing. Some other techniques that can be used to address this problem will be discussed later. The decal environment function performs simple alpha-blending between the fragment color and an RGBA texture; for RGB textures it simply replaces the fragment color.

Finally, if the display surface itself is non-planar, like the spherical and cylindrical screens used in some flight simulators, a combination of the above technique and image warping is required to produce an accurate image. Create a uniform grid as viewed by the observer. Project the vertices of the grid onto the screen surface. Project the vertices from the screen surface onto a plane perpendicular to the display direction of the video projector. Store the projected vertices’ normalized viewing coordinates coordinates for the original grid.
