compareTo
int Material::compare_to(Material const &other) const;

Description: Returns a number less than zero if this material sorts before the other one, greater than zero if it sorts after, or zero if they are equivalent. The sorting order is arbitrary and largely meaningless, except to differentiate different materials.

Description: Returns the default material.

getDiffuse
LVecBase4f const &Material::get_diffuse(void) const;

Description: Returns the diffuse color setting, if it has been set. Returns (1,1,1,1) if the diffuse color has not been set.

getEmission
LVecBase4f const &Material::get_emission(void) const;

Description: Returns the emission color setting, if it has been set. Returns (0,0,0,0) if the emission color has not been set.

Description: Returns true if the ambient color has been explicitly set for this material, false otherwise.

hasDiffuse
bool Material::has_diffuse(void) const;

Description: Returns true if the diffuse color has been explicitly set for this material, false otherwise.

hasEmission
bool Material::has_emission(void) const;

Description: Returns true if the emission color has been explicitly set for this material, false otherwise.

hasSpecular
bool Material::has_specular(void) const;

Description: Returns true if the specular color has been explicitly set for this material, false otherwise.

isAttribLocked
bool Material::is_attrib_locked(void) const;

Description:

operator !=
bool Material::operator !=(Material const &other) const;

Description:

operator <
bool Material::operator <(Material const &other) const;

Description:

operator =
void Material::operator =(Material const &copy);

Description:

operator ==
bool Material::operator ==(Material const &other) const;

Description:

output
void Material::output(ostream &out) const;

Description:

setAmbient
void Material::set_ambient(LVecBase4f const &color);

Description: Specifies the ambient color setting of the material. This will be the multiplied by any ambient lights in effect on the material to set its base color.
This is the color of the object as it appears in the absence of direct light.
If this is not set, the object color will be used.

setAttribLock
void Material::set_attrib_lock(void);

Description:

setDiffuse
void Material::set_diffuse(LVecBase4f const &color);

Description: Specifies the diffuse color setting of the material. This will be multiplied by any lights in effect on the material to get the color in the parts of the object illuminated by the lights.
This is the primary color of an object; the color of the object as it appears in direct light, in the absence of highlights.
If this is not set, the object color will be used.

setEmission
void Material::set_emission(LVecBase4f const &color);

Description: Specifies the emission color setting of the material. This is the color of the object as it appears in the absence of any light whatsover, including ambient light. It is as if the object is glowing by this color (although of course it will not illuminate neighboring objects).
If this is not set, the object will not glow by its own light and will only appear visible in the presence of one or more lights.

setLocal
void Material::set_local(bool local);

Description: Sets the local viewer flag. Set this true to enable camera-relative specular highlights, or false to use orthogonal specular highlights. The default value is true. Applications that use orthogonal projection should specify false.

setShininess
void Material::set_shininess(float shininess);

Description: Sets the shininess exponent of the material. This controls the size of the specular highlight spot. In general, larger number produce a smaller specular highlight, which makes the object appear shinier. Smaller numbers produce a larger highlight, which makes the object appear less shiny.

setSpecular
void Material::set_specular(LVecBase4f const &color);

Description: Specifies the diffuse color setting of the material. This will be multiplied by any lights in effect on the material to compute the color of specular highlights on the object.
This is the highlight color of an object: the color of small highlight reflections.
If this is not set, highlights will not appear.

setTwoside
void Material::set_twoside(bool twoside);

Description: Set this true to enable two-sided lighting. When two-sided lighting is on, both sides of a polygon will be lit by this material. The default is for two-sided lighting to be off, in which case only the front surface is lit.

write
void Material::write(ostream &out, int indent) const;

Description:

getClassType
static TypeHandle TypedWritableReferenceCount::get_class_type(void);

Undocumented function.

getClassType
static TypeHandle TypedWritable::get_class_type(void);

Undocumented function.

getClassType
static TypeHandle TypedObject::get_class_type(void);

Undocumented function.

getType
virtual TypeHandle TypedObject::get_type(void) const = 0;

Derived classes should override this function to return get_class_type().

getTypeIndex
int TypedObject::get_type_index(void) const;

Description: Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index().

isExactType
bool TypedObject::is_exact_type(TypeHandle handle) const;

Description: Returns true if the current object is the indicated type exactly.

isOfType
bool TypedObject::is_of_type(TypeHandle handle) const;

Description: Returns true if the current object is or derives from the indicated type.

getClassType
static TypeHandle ReferenceCount::get_class_type(void);

Undocumented function.

getRefCount
int ReferenceCount::get_ref_count(void) const;

Description: Returns the current reference count.

ref
void ReferenceCount::ref(void) const;

Description: Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

testRefCountIntegrity
bool ReferenceCount::test_ref_count_integrity(void) const;

Description: Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise.

testRefCountNonzero
bool ReferenceCount::test_ref_count_nonzero(void) const;

Description: Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise.

unref
bool ReferenceCount::unref(void) const;

Description: Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.

Namable
Namable::Namable(string const &initial_name = (""));

Description:

clearName
void Namable::clear_name(void);

Description: Resets the Namable's name to empty.

getClassType
static TypeHandle Namable::get_class_type(void);

Undocumented function.

getName
string const &Namable::get_name(void) const;

Description:

hasName
bool Namable::has_name(void) const;

Description: Returns true if the Namable has a nonempty name set, false if the name is empty.

operator =
Namable &Namable::operator =(Namable const &other);

Description:

output
void Namable::output(ostream &out) const;

In the absence of any definition to the contrary, outputting a Namable will write out its name.
Description: Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

setName
void Namable::set_name(string const &name);

Description:
