Detailed Description

Canvas for 3D-visualization of peak map data.

The Plot3DCanvas uses the helper class Plot3DOpenGLCanvas for the actual 3D rendering. Deriving Plot3DCanvas directly from QGLWidget is not possible due to the "Deadly Diamond" shape of inheritance.

Parameters of this class are:

Name	Type	Default	Restrictions	Description
default_path	string	.		Default path for loading/storing data.
background_color	string	@#ffffff		Background color
dot:shade_mode	int	1	min: 0 max: 1	Shade mode: single-color ('flat') or gradient peaks ('smooth').
dot:gradient	string	Linear\|0,@#ffea00;6,@#ff0000;14,@#aa00ff;23,@#5500ff;100,@#000000		Peak color gradient.
dot:interpolation_steps	int	1000	min: 1 max: 1000	Interpolation steps for peak color gradient precalculation.
dot:line_width	int	2	min: 1 max: 99	Line width for peaks.

Note:

If a section name is documented, the documentation is displayed as tooltip.
Advanced parameter names are italic.
