Method
CoglPipelineset_per_vertex_point_size
Declaration [src]
gboolean
cogl_pipeline_set_per_vertex_point_size (
  CoglPipeline* pipeline,
  gboolean enable,
  GError** error
)
Description [src]
Sets whether to use a per-vertex point size or to use the value set
by cogl_pipeline_set_point_size(). If per-vertex point size is
enabled then the point size can be set for an individual point
either by drawing with a CoglAttribute with the name
‘cogl_point_size_in’ or by writing to the GLSL builtin
‘cogl_point_size_out’ from a vertex shader snippet.
If per-vertex point size is enabled and this attribute is not used and cogl_point_size_out is not written to then the results are undefined.
Parameters
- enable
- 
            Type: gbooleanWhether to enable per-vertex point size. 
- error
- 
            Type: GError **The return location for a recoverable error. The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby the method if there are no errors.In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
