Pure virtual particle renderer base class.
BaseParticleRenderer::ParticleRendererAlphaMode getAlphaMode | ( | ) |
bool getIgnoreScale | ( | ) |
Returns the "ignore scale" flag.
See set_ignore_scale().
GeomNode getRenderNode | ( | ) |
Query the geomnode pointer.
NodePath getRenderNodePath | ( | ) |
Query the geomnode pointer.
float getUserAlpha | ( | ) |
gets alpha for "user" alpha mode
output | ( | Ostream | out | ) |
Write a string representation of this instance to <out>.
setAlphaMode | ( | BaseParticleRenderer::ParticleRendererAlphaMode | am | ) |
setColorBlendMode | ( | ColorBlendAttrib::Mode | bm, |
ColorBlendAttrib::Operand | oa, | ||
ColorBlendAttrib::Operand | ob | ||
) |
sets the ColorBlendAttrib on the _render_node
setIgnoreScale | ( | bool | ignore_scale | ) |
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 | ( | float | ua | ) |
sets alpha for "user" alpha mode
write | ( | Ostream | out, |
int | indent | ||
) |
Write a string representation of this instance to <out>.
