cannot find rgb info in placeholder

[iris0329]

Hi, Thanks for sharing this work!

in the paper, you said, the input is six channels, x, y, z, r, g, b. but I find in the code, it's

   pointclouds_pl = tf.placeholder(tf.float32, shape=(batch_size, num_point, 3))

it seems the input is three channels?

Thanks!
