<cat>struct</cat> <structure> <realm>Client</realm>⤶ <description> A structure containing vertex information for use with <page>surface.DrawPoly</page>. UV coordinates describe which part of a given texture should be drawn at a vertex - your graphics card's interpolator will fill in space between vertices. UV coords range from 0-1, with 0 being top/left and 1 being bottom/right. If you're using a texture these are mandatory. <note>You must pass a table of tables with this structure to the function. **You need to pass at least 3 points.**</note><note>Your points must be defined in a **clockwise order.** Otherwise, your shape will not render.</note> </description> <fields> <item name="x" type="number">The x coordinate of the vertex.</item> <item name="y" type="number">The y coordinate of the vertex.</item> <item name="u" type="number">The u texture coordinate of the vertex. `Can be left blank.`</item> <item name="v" type="number">The v texture coordinate of the vertex. `Can be left blank.`</item> </fields> </structure>
