Python RenderingContext Examples

Example #1

File: fits_idv.py Project: matthewturk/edge-notebooks

ds = yt.load(
    "/Volumes/Transcend/R_Tony/interpolated_co/xycut_co/done/NGC5908.co.xycut.K.fits",

shape = ds.domain_dimensions
v = ds.r[::1j * shape[0], ::1j * shape[1], ::1j * shape[2]]["intensity"]
print(v.min(), v.max())
v -= v.min()
v /= (v.max() - v.min())
v = 10**v
print(v.min(), v.max())

ds = yt.load_uniform_grid({'response': v},
                          v.shape,
                          bbox=np.array([[0.0, 1.0] for _ in 'xyz']))
rc = RenderingContext(960, 960)

rc = RenderingContext(960, 960, always_on_top=True)

dd = ds.all_data()
collection = ivr.BlockCollection(data_source=dd)
collection.add_data("response")

br = ivr.BlockRendering(data=collection,
                        vertex_shader="default.v",
                        fragment_shader="max_intensity.f",
                        colormap_vertex="passthrough.v",
                        colormap_fragment="apply_colormap.f")
