refraction_render.renderers.Scene¶

class refraction_render.renderers.Scene[source]¶

Bases: object

Simple wrapper which keeps track of data used to render an image.

__init__()[source]¶

This function initialized Scene object.

Methods

__init__()	This function initialized Scene object.
add_elevation_model(*args)	Add terrain data to the interpolated model.
add_image(image, image_pos, dimensions[, …])	Add image to scene.

Attributes

land_model

Object used to generate elevation along great circle.

add_elevation_model(*args)[source]¶

Add terrain data to the interpolated model.

Parameters

args: tuple

tuple which contains elevation data: if len(args) == 3: args = (lats,lons,elevation) which contains the arguments for scipy.interpolate.RegularGridInterpolator. if len(args) == 2: args = (points,elevation) which contains the arguments for scipy.interpolate.LinearNDInterpolator. if len(args) == 1: args = object that is instance of land_model.

add_image(image, image_pos, dimensions, direction=None)[source]¶

Add image to scene.

Parameters

image: str

string which contains path to image file.

image_pos: array_like

either has (h_obj,lat,lon) or (lat,lon) h_obj is height above the earth’s surface

dimensions: tuple

contains dimensions of the image is in meters. If either one has value -1 then that dimension is determined by the resolution of the picture.

property land_model¶

Object used to generate elevation along great circle.
