thinkingParticles introduces a new category of helper nodes; Geometry access helpers. In many situations, when creating advanced special effects, there is a need to query about object states and such queries can go even down to the face or vertex level of an object. The Geometry helper is specifically designed to do that.
ON - (Bool) This input data
stream determines whether the operator is considered 'on' or 'off.' You
can connect other operators to this input channel such as a Bool
Helper to activate/deactivate the whole operator.
Time - (Time) This input data stream is used to define the local
time for the operator when the user wants to override the default system
time.
Point Data - inputs a Point data type that can be easily created by the GeometryParticle helper node (closest point etc.).
Mapping Channel - default = 1, lets you specify the Mapping Channel to be used by this node
Color - outputs the color of the point specified by the Point Data input of this operator.
Material Index - outputs the material ID of the point specified by the Point Data input of this operator.
Normal - outputs the surface normal of the point specified by the Point Data input of this operator.
Position - outputs a vector representing the position in space of the requested point.
UVW - supplies the mapping coordinates from the selected Mapping Channel (if not specified by the Input it will be 1) at this point
Node - represents the max node if the point is from an object
Particle - is the particle ID if the point is coming form a particle shape
Velocity - outputs the velocity at this point
Normal - outputs the interpolated world space normal
Position OSpace - outputs the Position in Object Space
Face Normal OSpace - outputs the Face normal in Object Space
Normal OSpace - interpolated surface normal in Object Space
Alignment - outputs the alignment information
Face ID - outputs the face ID based on the point data
Object ID - outputs the Object ID for that point
There is no menu or UI options available.
