setStartColor void PointParticleRenderer::set_start_color(LVecBase4f const &sc); Undocumented function.

getAlphaMode BaseParticleRenderer::ParticleRendererAlphaMode BaseParticleRenderer::get_alpha_mode(void) const; Undocumented function.

getIgnoreScale bool BaseParticleRenderer::get_ignore_scale(void) const; Description : Returns the "ignore scale" flag. See set_ignore_scale().

getRenderNode GeomNode *BaseParticleRenderer::get_render_node(void) const; Filename: baseParticleRenderer.I Created by: charles (20Jun00) PANDA 3D SOFTWARE Copyright (c) 2001 - 2004, Disney Enterprises, Inc.

To contact the maintainers of this program write to panda3d-general@lists.sourceforge.net . Class : Published Description : Query the geomnode pointer

getRenderNodePath NodePath BaseParticleRenderer::get_render_node_path(void) const; Class : Published Description : Query the geomnode pointer

getUserAlpha float BaseParticleRenderer::get_user_alpha(void) const; Description : gets alpha for "user" alpha mode

output virtual void BaseParticleRenderer::output(ostream &out) const; Description : Write a string representation of this instance to <out>.

setAlphaMode void BaseParticleRenderer::set_alpha_mode(BaseParticleRenderer::ParticleRendererAlphaMode am); Undocumented function.

setColorBlendMode void BaseParticleRenderer::set_color_blend_mode(ColorBlendAttrib::Mode bm, ColorBlendAttrib::Operand oa = (O_zero), ColorBlendAttrib::Operand ob = (O_zero)); Description : sets the ColorBlendAttrib on the _render_node

setIgnoreScale void BaseParticleRenderer::set_ignore_scale(bool ignore_scale); Description : Sets the "ignore scale" flag. When this is true, particles will be drawn as if they had no scale, regardless of whatever scale might be inherited from above the render node in the scene graph. This flag is mainly useful to support legacy code that was written for a very early version of Panda, whose sprite particle renderer had a bug that incorrectly ignored the inherited scale.

setUserAlpha void BaseParticleRenderer::set_user_alpha(float ua); Description : sets alpha for "user" alpha mode

write virtual void BaseParticleRenderer::write(ostream &out, int indent = (0)) const; Description : Write a string representation of this instance to <out>.

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.
