Module utils

Utilities useful for various generations tasks.

Functions

• compute_normals
  Computes the normals of a set of vertices.
• push_circle
  Pushes a discretized counterclockwise circle to a buffer.
• push_degenerate_open_top_ring_indices
  Creates the faces from a circle and a point that is shared by all triangle.
• push_degenerate_top_ring_indices
  Creates the faces from a circle and a point that is shared by all triangle.
• push_filled_circle_indices
  Pushes indices so that a circle is filled with triangles. Each triangle will have the base_circle point in common. Pushes nsubdiv - 2 elements to out.
• push_open_ring_indices
  Creates the faces from two circles with the same discretization.
• push_rectangle_indices
  Given four corner points, pushes to two counterclockwise triangles to out.
• push_ring_indices
  Creates the faces from two circles with the same discretization.
• push_xy_arc
  Pushes a discretized counterclockwise circle to a buffer. The circle is contained on the plane spanned by the x and y axis.
• reverse_clockwising
  Reverses the clockwising of a set of faces.
• split_index_buffer
  Duplicates the indices of each triangle on the given index buffer.
• split_index_buffer_and_recover_topology
  Duplicates the indices of each triangle on the given index buffer, giving the same id to each identical vertex.
