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.
Objects - this port is used to feed one or many Objects into this operator to generate a object connection one must use the Object helper which offers an object output type
Face ID - sets the face ID for the object to be used from the list of objects, connected at the Objects input. Note: If this is not connected, the first object will be taken, only.
Object ID - sets the object ID for the object to be used from the list of objects, connected at the Objects input. Note: If this is not connected, the first object will be taken, only.
Face Coordinates - sets the face coordinates to get the get the point on the face. Face coordinates are Barycentric (this means all components added together should result in 1 to define a point "on" the face).
Mapping Channel - defines the mapping channel to be used by this Helper. When this is not connected it will be channel 1 by default.
Point - outputs point data of the center face point. This point data can be further processed by the GeomPoint helper.
Vertex ID 1-3 - outputs the 3 vertex ids of the triangle (face). This can be further processed by the GeomVertex helper.
UVW 1-3 - outputs the selected UVW channel coordinates for each vertex of the triangle (face).
There is no menu or UI options available.
