Surface receivers view

When clicking the Surface Receiver button you enter the Surface receiver view.

In the image above, we have a simulation with two surface receivers. By default, they are both selected, however it is possible to view only one at a time by clicking on Surface Receiver drop down and select/unselect desired surface receivers.

In the Surface receiver view you can view all the different parameters as surface receivers, switch between interpolated and simple heatmap, and pick the desired frequency.

Interpolated heatmap

The default view for heatmaps on surface receivers is the interpolated view. This view uses bilinear interpolation to estimate the values between the center of each square to draw the color gradient along the surface. The interpolation does not consider the model when drawing the heatmap, we recommend viewing both the interpolated and simple heatmap when evaluating acoustics of a space.

Simple heatmap

When disabling the interpolation, the heatmap shows each square with one color. The color shows the acoustic parameter value from the receiver in the middle of the square.

Colorbar

You can use the color bar next to each surface receiver parameter to understand the results better. The maximum and minimum values are auto assigned to the minimum and maximum of the values of the data. You can change the minimum and maximum values of the color bar by simply clicking the min or max values and inputting your desired value.

Frequency selector

You can change the frequency using the selector in the upper left corner.
