File In POP

Summary

The File In POP reads a file and converts it into a POP in GPU memory.

File formats:

.obj The Wavefront Object File Format supports faces (polygons) and line strips (f and l tags). Triangulation occurs for polygons with more than 3 sides. It supports texture UV coordinates (Texcoord) and normals. (it uses tinyobj internally)
.ply The Stanford Triangle Format supports faces (polygons) through the vertex_indices property in the face element. Polygons with 3 and 4 sides are converted to triangles and quadrelateral primitives in POPs. Polygons with more than 4 sides are converted to closed line strips. red, green, blue, alpha or r, g, b, a vertex elements will be read as Point Color within POPs.

Older formats are supported as well such as:

.tog TouchDesigner Geometry files are exports of other geometry types in a native TouchDesigner format
.bhclassic Houdini binary geometry format.
.hclassic Houdini ASCII geometry format.

You can use http:// URL prefix when specifying a supported file accessible on the network.

Some file formats can be read by both the File In POP and Point File In POP, with the difference being the File In POP only imports attributes and elements listed above. This is a list of files that both OPs can read.

.ply file format can contain custom attribute data
.obj file format

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.
