getColorScaleViaLighting bool GraphicsStateGuardian::get_color_scale_via_lighting(void) const; Description: Returns true if this particular GSG can implement (or would prefer to implement) set color and/or color scale using materials and/or ambient lights, or false if we need to actually munge the color. |
getCoordinateSystem CoordinateSystem GraphicsStateGuardian::get_coordinate_system(void) const; Description: Returns the coordinate system in effect on this particular gsg. Normally, this will be the default coordinate system, but it might be set differently at runtime. |
getCopyTextureInverted bool GraphicsStateGuardian::get_copy_texture_inverted(void) const; Description: Returns true if this particular GSG has the property that any framebuffer-to-texture copy results in a texture that is upside-down and backwards from Panda's usual convention; that is, it copies into a texture from the bottom up instead of from the top down. If this is true, then on offscreen GraphicsBuffer created for the purposes of rendering into a texture should be created with the invert flag set true, to compensate. Panda will do this automatically if you create an offscreen buffer using GraphicsOutput::make_texture_buffer(). |
getEngine GraphicsEngine *GraphicsStateGuardian::get_engine(void) const; Description: Returns the graphics engine that created this GSG. |
getGlobalGsg static GraphicsStateGuardian *GraphicsStateGuardian::get_global_gsg(void); Description: Returns the "global" GSG, which is to say, the GraphicsStateGuardian object that has most recently had make_global_gsg() called for it. It may return NULL if there is no such GSG. This object should be used for optimization hints where appropriate, for instance by operations like NodePath::flatten_strong(). |
getMax3dTextureDimension int GraphicsStateGuardian::get_max_3d_texture_dimension(void) const; Description: Returns the largest possible texture size in any one dimension for a 3-d texture, or -1 if there is no particular limit.

getMaxTextureDimension int GraphicsStateGuardian::get_max_texture_dimension(void) const; Description: Returns the largest possible texture size in any one dimension supported by the GSG, or -1 if there is no particular limit. The value returned may not be meaningful until after the graphics context has been fully created (e.g. the window has been opened). |
getMaxTextureStages int GraphicsStateGuardian::get_max_texture_stages(void) const; Description: Returns the maximum number of simultaneous textures that may be applied to geometry with multitexturing, as supported by this particular GSG. If you exceed this number, the lowest-priority texture stages will not be applied. Use TextureStage::set_priority() to adjust the relative importance of the different texture stages. The value returned may not be meaningful until after the graphics context has been fully created (e.g. the window has been opened). |
getMaxVertexTransformIndices int GraphicsStateGuardian::get_max_vertex_transform_indices(void) const; Description: Returns the maximum number of transforms there may be in a single TransformTable for this graphics hardware. If this number is 0 (but get_max_transforms() is nonzero), then the graphics hardware (or API) doesn't support indexed transforms, but can support direct transform references. The value returned may not be meaningful until after the graphics context has been fully created (e.g. the window has been opened). |
getMaxVertexTransforms int GraphicsStateGuardian::get_max_vertex_transforms(void) const; Description: Returns the maximum number of transform matrices that may be simultaneously used to transform any one vertex by the graphics hardware. If this number is 0, then the hardware (or the graphics backend) doesn't support soft-skinned vertices (in which case Panda will animate the vertices in software). The value returned may not be meaningful until after the graphics context has been fully created (e.g. the window has been opened). |
getMaxVerticesPerArray int GraphicsStateGuardian::get_max_vertices_per_array(void) const; Description: Returns the maximum number of vertices that should be put into any one GeomVertexData object for use with this GSG. |

getSupportsGenerateMipmap bool GraphicsStateGuardian::get_supports_generate_mipmap(void) const; Description: Returns true if this particular GSG can generate mipmaps for a texture automatically, or if they must be generated in software. If this is true, then mipmaps can safely be enabled for rendered textures (e.g. using the MultitexReducer). |
getSupportsRenderTexture bool GraphicsStateGuardian::get_supports_render_texture(void) const; Description: Returns true if this particular GSG can render directly into a texture, or false if it must always copy-to-texture at the end of each frame to achieve this effect. |
getSupportsShadowFilter bool GraphicsStateGuardian::get_supports_shadow_filter(void) const; Description: Returns true if this particular GSG supports the filter mode FT_shadow for depth textures. |
getSupportsTextureCombine bool GraphicsStateGuardian::get_supports_texture_combine(void) const; Description: Returns true if this particular GSG can use the TextureStage::M_combine mode, which includes all of the texture blend modes specified by set_combine_rgb() and/or set_combine_alpha(). If this is false, you must limit yourself to using the simpler blend modes. |

makeGlobalGsg void GraphicsStateGuardian::make_global_gsg(void); Description: Marks this particular GraphicsStateGuardian as the "global" GSG, which is used for optimization hints by operations like NodePath::flatten_strong(). |
prefersTriangleStrips bool GraphicsStateGuardian::prefers_triangle_strips(void) const; Description: Returns true if this GSG strongly prefers triangle strips to individual triangles (such as SGI), or false if it prefers to minimize the number of primitive batches, even at the expense of triangle strips (such as most PC hardware). |
releaseAll void GraphicsStateGuardian::release_all(void); Description: Releases all prepared objects. |
releaseAllGeoms int GraphicsStateGuardian::release_all_geoms(void); Description: Frees the resources for all geoms associated with this GSG. |

setActive void GraphicsStateGuardian::set_active(bool active); Description: Sets the active flag associated with the GraphicsStateGuardian. If the GraphicsStateGuardian is marked inactive, nothing is rendered. This is not normally turned off unless there is a problem with the rendering detected at a low level. |
setCoordinateSystem void GraphicsStateGuardian::set_coordinate_system(CoordinateSystem cs); Description: Changes the coordinate system in effect on this particular gsg. This is also called the "external" coordinate system, since it is the coordinate system used by the scene graph, external to to GSG. Normally, this will be the default coordinate system, but it might be set differently at runtime. |
getClassType static TypeHandle GraphicsStateGuardianBase::get_class_type(void); Undocumented function. |

getClassType static TypeHandle TypedWritableReferenceCount::get_class_type(void); Undocumented function. |
getClassType static TypeHandle TypedWritable::get_class_type(void); Undocumented function. |
getBestParentFromSet int TypedObject::get_best_parent_from_Set(set< int > const &) const; Description: Returns true if the current object is the indicated type exactly. |
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(). |

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 int 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. The return value is the new reference count. |
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. |
unref int 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 the new reference count. |
