Distorted rendering due to scaling

[haran2001]

Description

Scaling shader based actors beyond a point leads to either the actor completely disappearing or a distorted rendering of the actor.

Way to reproduce

• Code example

import numpy as np
from fury import window, actor

dirs = np.random.rand(4, 3)
colors = np.random.rand(4, 3) * 255
centers = np.array([[1, 0, 0], [0, 0, 0], [-1, 0, 0], [0, 1, 0]]) * 10
scales = np.array([1, 5, 10, 100])

sdfactor = actor.sdf(centers=centers, directions=dirs, colors=colors,
                     primitives=['torus', 'torus', 'torus', 'torus'],
                     scales=scales)

scene = window.Scene()
scene.background((1.0, 0.8, 0.8))
scene.add(sdfactor)


current_size = (1024, 720)
showm = window.ShowManager(scene, size=current_size,
                           title="Visualize SDF Actor")

interactive = True

if interactive:
    showm.start()
