int TypedWritable::complete_pointers | ( | TypedWritable ** | p_list, |
BamReader * | manager | ||
) | [virtual, inherited] |
Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().
Returns the number of pointers processed.
This is the callback function that is made by the BamReader at some later point, after all of the required pointers have been filled in. It is necessary because there might be forward references in a bam file; when we call read_pointer() in fillin(), the object may not have been read from the file yet, so we do not have a pointer available at that time. Thus, instead of returning a pointer, read_pointer() simply reserves a later callback. This function provides that callback. The calling object is responsible for keeping track of the number of times it called read_pointer() and extracting the same number of pointers out of the supplied vector, and storing them appropriately within the object.

bool TypedWritable::decode_raw_from_bam_stream | ( | TypedWritable *& | ptr, |
ReferenceCount *& | ref_ptr, | ||
const string & | data, | ||
BamReader * | reader = NULL |
||
) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts the single object on that string.
Returns true on success, false on on error.
This variant sets the TypedWritable and ReferenceCount pointers separately; both are pointers to the same object. The reference count is not incremented; it is the caller's responsibility to manage the reference count.
Note that this method cannot be used to retrieve objects that do not inherit from ReferenceCount, because these objects cannot persist beyond the lifetime of the BamReader that reads them. To retrieve these objects from a bam stream, you must construct a BamReader directly.
If you happen to know that the particular object in question inherits from TypedWritableReferenceCount or PandaNode, consider calling the variant of decode_from_bam_stream() defined for those methods, which presents a simpler interface.

void ReferenceCount::local_object | ( | ) | [inline, inherited] |
This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.
This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

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.

void Material::register_with_read_factory | ( | ) | [static] |
Factory method to generate a Material object.
Definition at line 230 of file material.cxx.
References BamReader::get_factory(), make_Material(), and Factory< Type >::register_factory().
bool TypedWritable::require_fully_complete | ( | ) | const [virtual, inherited] |
Some objects require all of their nested pointers to have been completed before the objects themselves can be completed.
If this is the case, override this method to return true, and be careful with circular references (which would make the object unreadable from a bam file).
Reimplemented in GeomVertexData, ClipPlaneAttrib, and RenderEffects.

void Material::set_ambient | ( | const Colorf & | color | ) |
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.
Definition at line 55 of file material.cxx.
void Material::set_diffuse | ( | const Colorf & | color | ) |
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.
Definition at line 80 of file material.cxx.
void Material::set_emission | ( | const Colorf & | color | ) |
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.

void Material::set_local | ( | bool | local | ) | [inline] |
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.
Definition at line 256 of file material.I.
void Material::set_shininess | ( | float | shininess | ) | [inline] |
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.
Definition at line 232 of file material.I.
void Material::set_specular | ( | const Colorf & | color | ) |
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.
Definition at line 104 of file material.cxx.
void Material::set_twoside | ( | bool | twoside | ) | [inline] |
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.

bool ReferenceCount::test_ref_count_integrity | ( | ) | const [inline, inherited] |
Does some easy checks to make sure that the reference count isn't completely bogus.

bool ReferenceCount::unref | ( | ) | const [inline, virtual, inherited] |
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.) 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.
