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.

Stability:	Unstable
Available since:	2.0

Parameters

`enable`	`gboolean`
	Whether to enable per-vertex point size.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`gboolean`
	`TRUE` if the change succeeded or `FALSE` otherwise.
