3D VIEW

3D Terrain Viewer

STREAM's 3D terrain viewer renders your DEM in a fast GPU-driven 3D view. Fly across gigabyte DEMs and orthophotos at full resolution, switch instantly between 2D and 3D, and see analysis and imagery draped on the real surface.

Why a real 3D view helps

A flat map hides slope and shape. Seeing the DEM in true 3D — with the orthophoto and analysis draped on it — makes the terrain immediately readable and helps spot problems a plan view misses.

STREAM's renderer is built for scale, so the 3D view stays smooth even on very large datasets.

GPU terrain rendering

A Vulkan compute renderer draws the terrain at full resolution in 3D, without dropping detail.

2D and 3D

Switch instantly between a plan (2D) view and a perspective (3D) view as the task needs.

Imagery & analysis draped

See orthophotos and analysis overlays wrapped onto the real 3D surface.

Fly-throughs

Move smoothly across the site and record fly-through views for presentation.

How to explore terrain in 2D and 3D

1
Frame the site
Fit to data brings every loaded and visible layer into view in one click, so you never start lost.
2
Choose the view mode
2D is the plan view for drawing, measuring and map sheets. 3D is the free camera for slopes, benches and design checks. Double-clicking the compass returns to top view.
3
Decide what is drawn
Turn the orthophoto on or off — with it off the terrain reads as slope-shaded grey — and manage the legend, scale bar and guides.
4
Navigate
Pan, zoom and orbit at full resolution; the terrain is raycast, so detail does not drop as you zoom in. The cursor shows X/Y/Z the whole time.
5
Record a fly-through
Set the camera path and record the movement as a video for presentation.
