Functions

clear	Clear all custom meshes
create	Create Texture objects
delete	Delete Texture objects

Classes

Texture

clear()

Clear all custom meshes

class Texture(position=None, offset=None, texture_file=None)

Bases: object

create()

Creates Textures

Parameters

none

Examples >>> tex = urchin.texture.Texture()

delete()

Deletes Textures

Parameters

references object being deleted

Examples >>> tex.delete()

set_position(positions)

Set the position of fov in ap/ml/dv coordinates relative to the CCF (0,0,0) point

Parameters

positionlist of list of three floats

vertex positions of the four corners of the texture relative to the CCF origin

Examples

>>> tex.set_position([[9.2611688 , 7.94252654, 1.3904818 ],
        [8.75443871, 7.94252654, 1.08008647],
        [9.24259926, 8.52829154, 1.43690564],
        [8.73586918, 8.52829154, 1.12651031]])

set_image(array)

Set the image data for texture

Parameters

arraynumpy array

luminance data for texture

Examples

>>> tex.set_texture(array)

set_offset(offset)

Set the vertical offset for this texture

Parameters

offsetfloat

Vertical offset in mm

create(N)

Create Texture objects

Note: textures must be created before setting other values

Parameters

Nint

number of new Texture objects

Examples

>>> textures_list = urchin.textures.create(3)

delete(textures_list)

Delete Texture objects

Parameters

textures_list : list of Texture

Examples

>>> urchin.fovs.delete(textures_list)

set_positions(textures_list, positions_list)

Set the positions of textures in ap/ml/dv coordinates relative to the CCF (0,0,0) point

Note: this plural function has no efficiency advantage of Texture.set_position, for readable code we recommend using the former.

Parameters

textures_listlist of fov objects

list of fovs being moved

positionslist of list of list of three floats

list of four vertex corners for each texture

Examples

>>> urchin.fovs.set_positions([[...],[...],[...]]) # see set_position for position example

set_images(textures_list, images_list)

Set the position of fov in ml/ap/dv coordinates relative to the CCF (0,0,0) point

Parameters

fovs_listlist of fov objects

list of fovs being moved

positionslist of list of three floats

list of positions of fovs

Examples

>>> img0 = fov.
>>> urchin.fovs.set_textures([f1,f2,f3], ['fov1.png','fov'])
