// CLASS DESCRIPTION (MFnParticleSystem)
|
|
//
|
|
// Particle object access class. Intended to be used by the software
|
|
// renderer for accessing relevant data from the particle object. The
|
|
// data stored in the particle object is a function of the particle
|
|
// render type.
|
|
//
|
|
// Safe to call these methods with any render type:
|
|
//
|
|
// Method Name Description
|
|
// ================================================================
|
|
// isValid() data is valid (predicate)
|
|
// renderType() object render type
|
|
// count() particle count at current frame
|
|
// ----------------------------------------------------------------
|
|
//
|
|
//
|
|
// Use this table to determine which methods to call based on the
|
|
// render type of the particle object.
|
|
//
|
|
// Render Type Valid Methods Description
|
|
// ================================================================
|
|
// kCloud position() particle position
|
|
// radius() particle radius
|
|
// surfaceShading() object surface shading value
|
|
// betterIllum() invoke thick cloud sampling
|
|
// threshold() object threshold
|
|
// disableCloudAxis() for internal use; do not call
|
|
// ----------------------------------------------------------------
|
|
// kTube position0() particle start position
|
|
// position1() particle end position
|
|
// radius0() particle start radius
|
|
// radius1() particle end radius
|
|
// tailSize() length scale factor
|
|
// ----------------------------------------------------------------
|
|
// kBlobby position() particle position
|
|
// radius() particle radius
|
|
// threshold() object threshold
|
|
// ----------------------------------------------------------------
|
|
// kHardware position() particle position
|
|
// radius() particle radius
