fsleyes.gl.gl14.gllabel_funcs
¶
This module provides functions which are used by the GLLabel
class to render Image
overlays in an OpenGL 1.4 compatible manner.
Rendering of a GLLabel
is very similar to that of a GLVolume
,
with the exception that a different fragment program (gllabel
) is used.
Therefore, the preDraw
, draw
, drawAll
and postDraw
functions
defined in the gl14.glvolume_funcs
are re-used by this module.
- fsleyes.gl.gl14.gllabel_funcs.init(self)[source]¶
Calls the
compileShaders()
andupdateShaderState()
functions.
- fsleyes.gl.gl14.gllabel_funcs.destroy(self)[source]¶
Deletes handles to the vertex/fragment shader programs.
- fsleyes.gl.gl14.gllabel_funcs.compileShaders(self)[source]¶
Loads vertex and fragment shader program source, and creates an
ARBPShader
instance.
- fsleyes.gl.gl14.gllabel_funcs.updateShaderState(self)[source]¶
Updates all shader program variables.
- fsleyes.gl.gl14.gllabel_funcs.draw2D(self, *args, **kwargs)[source]¶
Draws the label overlay in 2D. See
GLObject.draw2D()
.
- fsleyes.gl.gl14.gllabel_funcs.drawAll(self, *args, **kwargs)[source]¶
Draws the label overlay in 2D. See
GLObject.draw2D()
.
