fig_v2报错

[oulton]

fig_v2显示带颜色的，color参数会报错 traits.trait_errors.TraitError: The 'color' trait of a GlyphFactory instance must be a tuple of the form: (0.0 <= a floating point number <= 1.0, 0.0 <= a floating point number <= 1.0, 0.0 <= a floating point number <= 1.0) or None, but a value of array([ 75., 101., 87.]) <class 'numpy.ndarray'> was specified.

color参数要0-1之间的，点云颜色RGB是0-255, 我试着color/255归一化了，发现并不能解决问题

[oulton]

发现问题了，color/255归一化后应该是可以的，可能是我这边点云比较大，会导致绘制很慢 卡死的状态

先归一化再转元组格式，跑一个小点云5GB内存都没加载出来... `

def fig_v2(structure, colors):

colors = colors / 255

colors = colors.tolist()

for i in range(len(structure)):

    rgb = tuple(colors[i])

    mlab.points3d(structure[i][0], structure[i][1], structure[i][2],  mode = 'point', name = 'dinosaur', color = rgb)

mlab.show()
