How to add a command to minib3d to turn off texture filtering
You will need to patch some files
Step 1: Open TMesh.bmx and scroll down until you find:
' mipmapping texture flag
If tex_flags&8<>0
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR)
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR_MIPMAP_LINEAR)
Else
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR)
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR)
EndIfChange it to look like:' mipmapping texture flag
If(THardwareInfo.TextureFilters)
If tex_flags&8<>0
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR)
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR_MIPMAP_LINEAR)
Else
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR)
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR)
EndIf
Else
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_NEAREST)
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_NEAREST)
EndIfStep 2: Open THardwareInfo.bmx and add-
Global TextureFilters : Int = 1 -at the end of the globals (e.g. under MaxLights)
Step 3: Open functions.bmx and add this wherever you think is comfortable
Rem
bbdoc: MiniB3D Only
about: Enables/disables texturefilters.
The command enables/disables texture filters on meshes.
End Rem
Function TextureFilters(boolean:Int)
THardwareInfo.TextureFilters = boolean
End Function
Rem
bbdoc: MiniB3D Only
about: Returns the value of TextureFilters.
The command returns wether TextureFilters is enabled or not.
End Rem
Function GetTextureFilters:Int()
Return THardwareInfo.TextureFilters
End Function
To use, put TextureFilters(boolean) in your main file
True blurs textures like before and false pixelates textures like Doom!
ENJOY!
