void CLOSTexture::BindTexture

(

int

unit

)

Recomputes the LOS texture if necessary, and binds it to the requested texture unit.

Also switches the current active texture unit, and enables texturing on it. The texture is in 8-bit ALPHA format.

const float * CLOSTexture::GetMinimapTextureMatrix

(

)

Returns a matrix to map (0,0)-(1,1) texture coordinates onto LOS texture coordinates, in the form expected by glLoadMatrixf.

This must only be called after BindTexture.

Definition at line 190 of file LOSTexture.cpp.

GLuint CLOSTexture::GetTexture

(

)

Recomputes the LOS texture if necessary, and returns the texture handle.

Also potentially switches the current active texture unit, and enables texturing on it. The texture is in 8-bit ALPHA format.

Definition at line 173 of file LOSTexture.cpp.

const CMatrix3D & CLOSTexture::GetTextureMatrix

(

)

Returns a matrix to map (x,y,z) world coordinates onto (u,v) LOS texture coordinates, in the form expected by glLoadMatrixf.

This must only be called after BindTexture.

Definition at line 184 of file LOSTexture.cpp.

Definition at line 114 of file LOSTexture.cpp.

void CLOSTexture::MakeDirty

(

)

Marks the LOS texture as needing recomputation.

Call this after each simulation update, to ensure responsive updates.
