Experimental:Circle POP

Summary

The Circle POP creates a number of points in a circle, ellipse or arc, and optionally connects them as a line strip, a set of triangles, separate 2-point lines, or unconnected as point primitives. You can choose to not Close the circle, where the last point/section is not connected to first.

You can add texture coordinate, normal or tangent attributes to the points or to the vertices. Of note are normals, which can optionally point radially away from the center, or tangent to the circle.

Orientation can be in any of the XY, YZ or ZX planes and then further rotated and translated.m

If a POP is connected to the input, it will translate / scale the circle to the bounding box of the input. If a POP is connected to the input and if Modify Bounds is set, it will scale / translate the circle to the bounding box of the input, and you can further translate/scale/rotate the circle.

Common POP Info Channels

Common Operator Info Channels

total_cooks - Number of times the operator has cooked since the process started.

cook_time - Duration of the last cook in milliseconds.

cook_frame - Frame number when this operator was last cooked relative to the component timeline.

cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.

cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.

cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.

cooked_this_frame - 1 if operator was cooked this frame.

warnings - Number of warnings in this operator if any.

errors - Number of errors in this operator if any.
