visual_stim package

Submodules

visual_stim.base module

Base stimulus class.

Handles GL context, shader programs common to all stimpack.visual_stim stim classes.

See stimpack.visual_stim.stimuli for available child stimulus classes. Overwrite methods in child classes like:

configure eval_at

class stimpack.visual_stim.base.BaseProgram(screen, num_tri=500)

Bases: object

add_texture_gl(texture_image, texture_interpolation='LINEAR')

configure(*args, **kwargs)

create_prog()

destroy()

eval_at(t, subject_position={'phi': 0, 'roll': 0, 'theta': 0, 'x': 0, 'y': 0, 'z': 0})

Parameters:

t – current time in seconds

get_fragment_shader()

get_vertex_shader()

initialize(ctx)

Parameters:

ctx – ModernGL context

paint_at(t, viewports, perspectives, subject_position={'phi': 0, 'theta': 0, 'x': 0, 'y': 0, 'z': 0})

Parameters:

• t – current time in seconds

• viewports – list of viewport arrays for each subscreen - (xmin, ymin, width, height) in display device pixels

• perspectives – list of perspective matrices for each subscreen, generated using perspective.GenPerspective and subscreen corners

• subject_position – x, y, z position of subject (meters)
