Description

Presently the maximum distance specified in a Detail definition is ignored. Doomsday should use this value as a factor when generating the mip level textures to progressively ramp up/down the rate at which they blend to grey.

History

#1 Updated by skyjake about 14 years ago

Mipmap levels depend on screen resolution, so if they are used for this purpose they have to take the screen dimensions into account.

The default detail texture visibility limit is (was?) 256 units.

#2 Updated by danij over 12 years ago

Rather than modifying the mip levels it would be a whole lot easier to use GL_TEXTURE_LOD_BIAS to apply the maximum distance.

Using the mip level approach is problematic because the maximum distance varies for each detail texture definition and texture file combination. This is further complicated by the fact we need to provide the user with a distance factor multiplier.
