<\/a><\/p>\nThe user can ‘fly through’ the model on-screen and examine every aspect of it.\u00a0\u00a0Because noise contours\u00a0and receiver noise levels have been calculated, these\u00a0are also\u00a0shown in the 3-D view.<\/p>\n
This makes it far easier to appreciate the noise impact of a scheme, or to check for modelling errors, although it may take some time to generate the ‘solid’ 3-D model, as this requires a complex mathematical process.<\/p>\n
Below, the figure shows the plan view of the\u00a0road passing over\u00a0the railway but it is hard to see\u00a0this in the plan view.<\/p>\n
Below, the 3-D view makes the height of objects clear. It also shows the noise levels at receiver points at various heights on adjacent buildings. The viewpoint is shown by the white pointer in the plan view above.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" The 3-D viewer helps with understanding the height\u00a0of objects within a model, which is important because height makes a great difference to noise propagation. Here we have a perspective (3-D) view of a road passing on a bridge over a railway.\u00a0 Two railway\u00a0lines are in a cutting.\u00a0 The ground is coloured according to noise from … Continue reading 3-D Viewing<\/span> <\/a><\/p>\n<\/a><\/p>\n
