opengl/light provides all methods to deal with openGL light settings. The file only contains 1 class:

• Light

Class Light

This class is used to create all light effects used by shaders in openGL

Variables

These variables are all preset by __init__.

name	description
glob	reference to global object.
shaderInit	reference to global shader initialization object.
shaders	List of all shaders.
phong	references phong shader.
pbr	references pbr shader.
toon	references toon shader.
min_coords	minimal values of the scene in units as a list.
max_coords	maximal values of the scene in units as a list.
glclearcolor	Color as QVector4D to clear openGL
ambientLight	ambientLight as QVector4D
lightWeight	lightWeight as QVector3D, x is luminance, y is focus
blinn	Phong shading, boolean, true if mode blinn is used.
skybox	Determines if skybox is used.
skyboxname	Name of the skybox.
lights	List of 3 dictionaries with lights, each one represented as position, volume (color), intensity and type (directional or point).

Methods:

name	parameters	returns	description
numlights	None	number of lights	returns number of lights (3).
listTo3D	vector elems (list)	None	set components of QVector3D from list.
listTo4D	vector elems (list)	None	set components of QVector4D from list.
q3ToList	v (QVector3D)	list of 3 elements	Converts QVector3D to list.
q4ToList	v (QVector4D)	list of 4 elements	Converts QVector4D to list.
fromGlobal	load_json (bool)	None	set all values from either reading the shader-init JSON file by first setting shaderInit or uses these variables directly without re-reading the file.
toGlobal	None	None	Replaces the variables of global file with new values.
setShader	None	None	bind phong, pbr and toon shader with the new settings.
useBlinn	value	None	set blinn parameter of shader to value (True or False).
useSkyBox	value	None	set skybox parameter to value (True or False).
getAmbientLuminance	None	luminance	return ambientLight.w() (last parameter of luminance QVector4D)
setAmbientLuminance	value	None	sets last parameter of ambientLight QVector4D to value.
setSpecularLuminance	value	None	sets first parameter of lightWeight QVector3D to value.
setSpecularFocus	value	None	sets second parameter of lightWeight QVector3D to value.
getClearColor	None	rounded list of 3 floats	Returns current clear-color.
setClearColor	value	None	sets clear-color QVector4D. Transparent value is set to 1.0
getAmbientColor	None	rounded list of 3 floats	Returns current ambient color.
setAmbientColor	value	None	sets first 3 values of ambientLight QVector4D.
setHPos	lnum height	None	sets height of light lnum.
setLPos	lnum x y	None	sets x and y position of light lnum.
getLPos	lnum	position as list	returns the position of light lnum.
setType	lnum ltype	None	sets type of light lnum.
getType	lnum	type	returns type of light lnum.
setLLuminance	lnum value	None	set intensity of luminance of light lnum.
getLLuminance	lnum	luminance	returns intensity of luminance of light lnum.
setLColor	lnum value	None	sets RGB color from value for light lnum.
getLColor	lnum	RGB color as a list of 3 floats	returns RGB color of light lnum.
