创建文本框
push_edit gui.TextEdit()创建button
push_button gui.Button(...)
push_button.horizontal_padding_em 0.5
push_button.vertical_padding_em 0
push_button.set_on_clicked(self._on_push_button) # 设置回调函数创建布局
# 文本框和按钮水平布局
push_button_layout gui.Horiz()
push_button_layout.add_child(gui.Label(Push Button))
push_button_layout.add_child(self._push_edit)
push_button_layout.add_fixed(0.25*em)
push_button_layout.add_child(push_button)# 总体垂直布局
self.pannel gui.Vert()
self.pannel.add_fixed(0.5*em)
self.pannel.add_child(push_button_layout)
self.window.add_child(self.pannel)绘制形状
绘制线段

设置线宽

material_default.shader unlitLine
material_default.line_width 3
self._scene.scene.add_geometry(lines, object_lines, material_default)设置点大小
material o3d.visualization.rendering.Material()
material.shader defaultLit
material.base_color color
material.point_size size
scene.add_geometry(name, cloud, material)可用Shader汇总

类型 适用shader 网格defaultLit/defaultLitTransparency、normals点云defaultLit/defaultLitTransparency、normals、defaultUnlit/defaultUnlitTransparency线段最好unlitLine只有这个可以控制线宽
