Panda3D Manual: Particle Renderers
<<prev | top | next>>
Particle renderers add particles to the visible scene graph according to the information stored in the particle objects and the type of renderer. All particle renderers have the following parameters:
Variable | Definition | Values
alphaMode | Alpha setting over particle lifetime | PR_ALPHA_NONE, PR_ALPHA_OUT, PR_ALPHA_IN, PR_ALPHA_USER
userAlpha | Alpha value for ALPHA_USER alpha mode | Boolean
The following list contains the different types of renderers and their unique parameters. ### PointParticleRenderer Renders particles as pixel points.
Variable | Definition | Values
pointSize | Width and height of points, in pixels | [0, infinity)
startColor | Starting color | (r, g, b, a)
endColor | Ending color | (r, g, b, a)
blendType | How the particles blend from the start color to the end color | ONE_COLOR, BLEND_LIFE, BLEND_VEL
blendMethod | Interpolation method between colors | LINEAR, CUBIC
ONE_COLOR: point is always the starting color. BLEND_LIFE: color is interpolated from start to end according to the age of the point BLEND_VEL: color is interpolated between start to end according to the velocity/terminal velocity. ### LineParticleRenderer Renders particles as lines between their current position and their last position.
Variable | Definition | Values
headColor | Color of leading end | (r, g, b, a)
tailColor | Color of trailing end | (r, g, b, a)
### SparkleParticleRenderer Renders particles star or sparkle objects, three equal-length perpendicular axial lines, much like jacks. Sparkle particles appear to sparkle when viewed as being smaller than a pixel.
Variable | Definition | Values
centerColor | Color of center | (r, g, b, a)
edgeColor | Color of edge | (r, g, b, a)
birthRadius | Initial sparkle radius | [0, infinity)
deathRadius | Final sparkle radius | [0, infinity)
lifeScale | Whether or not sparkle is always of radius birthRadius | NO_SCALE, SCALE
### SpriteParticleRenderer Renders particles as an image, using a Panda3D texture object. The image is always facing the user.
Variable | Definition | Values
texture | Panda texture object to use as the sprite image | (r, g, b, a)
color | Color | (r, g, b, a)
xScaleFlag | If true, x scale is interpolated over particle’s life | Boolean
yScaleFlag | If true, y scale is interpolated over particle’s life | Boolean
animAngleFlag | If true, particles are set to spin on the Z axis | Boolean
initial_X_Scale | Initial x scaling factor | [0, infinity)
final_X_Scale | Final x scaling factor | [0, infinity)
initial_Y_Scale | Initial y scaling factor | [0, infinity)
final_Y_Scale | Final y scaling factor | [0, infinity)
nonAnimatedTheta | If false, sets the counterclockwise Z rotation of all sprites, in degrees | Boolean
alphaBlendMethod | Sets the interpolation blend method | LINEAR, CUBIC
alphaDisable | If true, alpha blending is disabled | Boolean
### GeomParticleRenderer Renders particles as full 3D objects. This requires a geometry node.
Variable | Definition | Values
geomNode | A geometry scene graph node | <Node>
