`fsleyes.gl.gl14.glrgbvolume_funcs`¶

This module contains functions used by the GLRGBVolume class for rendering RGB(A) Image overlays in an OpenGL 1.4 environment.

fsleyes.gl.gl14.glrgbvolume_funcs.init(self)[source]¶: Compiles and initialises the shader program.

fsleyes.gl.gl14.glrgbvolume_funcs.destroy(self)[source]¶: Destroys the shader program.

fsleyes.gl.gl14.glrgbvolume_funcs.compileShaders(self)[source]¶: Loads the vertex/fragment shader source code, and creates a GLSLShader program.

fsleyes.gl.gl14.glrgbvolume_funcs.updateShaderState(self)[source]¶: Updates all shader program variables.

fsleyes.gl.gl14.glrgbvolume_funcs.draw2D(self, zpos, axes, xform=None, bbox=None)[source]¶: Draws a 2D slice at the given zpos. Uses the gl14.glvolume_funcs.draw2D() function.

fsleyes.gl.gl14.glrgbvolume_funcs.drawAll(self, axes, zposes, xforms)[source]¶: Draws all specified slices. Uses the gl14.glvolume_funcs.drawAll() function.
