VEX snippets

Beacon comes with additional VEX snippets that you can use in an Attribute Wrangle. To access them, simply click the down arrow next to VEXpression in the node parameters.

Usage

All the snippets are coming from the VEXpressions.txt file. They should be written this way:

attribwrangle/snippet
    Snippet name (Type) | Beacon
    // Run over <type>
    Snippet code
Example
VEXpressions.txt
attribwrangle/snippet
    Basic Scatter (Point) | Beacon
    // Run over point
    vector up = {0, 1, 0};
    vector4 orient2;
    vector rot = set( rand(@ptnum+1)*ch("random_x")*360, rand(@ptnum+2)*ch("random_y")*360, rand(@ptnum)*ch("random_z")*360);
    orient2 = eulertoquaternion(radians(rot), 0);
    matrix3 m = maketransform(@N, up);
    @orient = quaternion(m);
    @orient = slerp(@orient, orient2, ch("mix"));
    @pscale = ch("scale")+rand(@ptnum)*ch("random_scale");

After a Houdini restart, the new expression will be available.
