ViewportInfoGetPointDepth Method

Gets the clipping distance of a point. This function ignores the current value of the viewport's near and far settings. If the viewport is a perspective projection, then it intersects the semi infinite frustum volume with the bounding box and returns the near and far distances of the intersection. If the viewport is a parallel projection, it intersects the infinite view region with the bounding box and returns the near and far distances of the projection.

A point to measure.
distance

Type: Boolean
true if the bounding box intersects the view frustum and near_dist/far_dist were set. false if the bounding box does not intersect the view frustum.
