Experimental:Math Combine POP

Summary

The Math Combine POP can do numerous math operations in one node, and is an expansion of the more elementary Math POP and Math Mix POP:

In addition to what Math Mix does:

On the New page it lets you create new attributes with constant values, with more control over type and size, usable in the Combine page and output directly unless you delete them on the Output page.
On the Pre page it has a set of pre-process blocks where you operate on one attribute per block, similar to the Math POP.
On the Post page it has a set of post-process blocks after the Combine page, operating on one attribute at a time again, with re-ranging.
On the Output page it gives more control over keeping or deleting temporary attributes.

Handling Inputs: Math Combine handles inputs differently than Math Mix: In the Math Combine POP you explicitly select the attributes from all the inputs, you can rename them, and these selected attributes go to the output (unless you delete them on the output page). Math Mix POP auto-names all the inputs’ attributes (in2_Tex for example), but the attributes don’t go to the output except for the first input's attributes. Math Combine POP treats inputs the same way as the Attribute Combine POP, which essentially hides which POPs the attributes come from. Note that anything you select on the Inputs page does not copy the attribute data - it remains as all references to attribute arrays in the incoming POPs.

The difference between the Uniforms page an the New page: The New pages creates a full array of data, one per point constant value per point, and it is output from the POP like any attribute. Uniforms are named constant values that does not create any new data and is not output from the POP.

The Pre page and Post page (similar to the Math POP) are sequential blocks that operate on one parameter per block, with these parameters:

Scope - which attribute to operate on
Parameter Size (default 1) (Parameter Size means how many sets of parameters, like Parameter Size of 3 will present a set of parameters for each of X, Y and Z.
Pre page has:
- Order menu (Add Multiply Op, Multiply Add Op, Op Add Multiply, Op Add Multiply)
- Multiply float
- Add float
- Operation - all the unary operations of the Combine page
Post page has:
- Re-ranging parameters
- casting to integers, doubles, floats
Quantize - rounding and also logic operations (> 0, == 0, …)
Result Scope (in which attribute to put the result, whether it is an existing set of components or a new attribute)

Output page:

Delete Attributes - which ones to delete from the output
Delete New Attributes toggle
Output Secondary Attributes - outputs ones created in the POP

Note that on the Common page you can select to output only the attributes that were affected in the POP, useful for cases where you want to output one attribute per POP.

Note the pop-up info contains pseudocode of the operations in this POP, for easier reading.

Attaching an Info DAT will show you raw GLSL code that is generated.
