Member Function Documentation

void CLwoSurface::apply_properties ( EggPrimitive * egg_prim,

vector_PT_EggVertex & egg_vertices,

float & smooth_angle

)

Applies the color, texture, etc.
described by the surface to the indicated egg primitive.
If the surface defines a smoothing angle, smooth_angle may be updated to reflect it if the angle is greater than that specified.

bool CLwoSurface::check_material ( )

Checks whether the surface demands a material or not.
Returns true if so, false otherwise.

bool CLwoSurface::check_texture ( )

Checks whether the surface demands a texture or not.
Returns true if so, false otherwise.
If the surface demands a texture, this also sets up _egg_texture and _compute_uvs as appropriate for the texture.

void CLwoSurface::generate_uvs ( vector_PT_EggVertex & egg_vertices ) [private]

Computes all the UV's for the polygon's vertices, according to the _projection_mode defined in the block.

Definition at line 393 of file cLwoSurface.cxx.

const string & CLwoSurface::get_name ( ) const [inline]

Returns the name of the surface.
Each surface in a given Lightwave file should have a unique name.

References _block, CLwoSurfaceBlock::_projection_mode, INLINE, LwoSurfaceBlockProjection::M_uv, and NULL.

const string & CLwoSurface::get_uv_name ( ) const [inline]

Returns the name of the set of UV's that are associated with this surface, if has_named_uvs() is true.

Definition at line 73 of file cLwoSurface.I.
Referenced by CLwoPolygons::make_faces().

bool CLwoSurface::has_named_uvs ( ) const [inline]

Returns true if the surface is set up to reference UV's stored on the vertices, by name (as opposed to generated UV's, which is the more common Lightwave case).
In this case, get_uv_name() can be called to return the name of the UV's.
