fsleyes.gl.gl21.glvector_funcs

This module contains logic for managing vertex and fragment shader programs used for rendering GLRGBVector and GLLineVector instances. These functions are used by the gl21.glrgbvector_funcs and gl21.gllinevector_funcs modules.

fsleyes.gl.gl21.glvector_funcs.compileShaders(self, vertShader, indexed=False)

Compiles the vertex/fragment shader programs (by creating a GLSLShader instance).

If the VectorOpts.colourImage property is set, the glvolume fragment shader is used. Otherwise, the glvector fragment shader is used.

fsleyes.gl.gl21.glvector_funcs.updateShaderState(self, useSpline=False)

Updates the state of the vector vertex fragment shader. The fragment shader may be either the glvolume or the glvector shader.
