Returns vertex color settings from a range of vertices without having to open each vertex.
key | - Key to the piece of geometry to query. |
geometry | - Type of geometry referred affected by the color value. This can be either "vertex", "edge", or "face". |
offset | - Index of the key's point array on which to start querying values. |
count | - Number of points from offset to query. |
result_type | - An array of size count whose values would be populated with either 0, 1, 2 or 3 describing what type of color value was set (see details for more information). Passed by reference. Returned to user. |
index_colors | - An array of size count populated with the index color value. Passed by reference. Returned to user. |
rgb_colors | - Array of (r, g, b) triplets whose size is count. Passed by reference. Returned to user. |
rgba_colors | - Array of (r, g, b, a) quads whose size is count. Passed by reference. Returned to user. |
Use MShow_Vertex_Colors_With_Existence to query vertex color values efficiently. Since color values may or may not exist, the return values gives you the total number of color values that have been set. The result_type array gives you further information about each vertex's color setting. For a given vertex, the result_type value may be one of the following:
