Terragen vs TouchDesigner

Terragen builds, renders, and animates natural environments for landscape visualization, visual effects, and artistic work. It creates procedural and heightfield terrain, can use real-world terrain data, and adds details such as cliffs and overhangs. Its spherical planetary atmosphere model includes volumetric clouds and fog, multiple scattering, and global illumination. The hybrid renderer combines micropolygon rendering and ray tracing, with support for anti-aliasing, motion blur, depth of field, and render elements. Nearly every project parameter can be animated, and image sequences can be rendered through the interface or command line. Terragen imports 3D objects and camera data, exports terrain as heightfields or geometry in formats including TER, EXR, LWO, OBJ, and FBX, and handles camera data in FBX, Nuke CHAN, and Maya MOV formats. It can also generate HDR environments for lighting in other renderers. Windows and macOS are supported, with Linux render-node support. The free edition is for non-commercial use or 30 days of commercial evaluation, with still renders limited to 1280 × 900. Professional subscriptions start at $10 a month.

TouchDesigner is real-time software for creating interactive 2D and 3D animation, art, media, and visualizations. It combines an application engine and interface in one environment, supporting work from prototypes to finished applications. Its control panel features can be used to build custom interfaces for mouse, touchscreen, gestural, and multi-person input. The software supports high-performance media systems, ultra-resolution video playback, custom media servers, and projection mapping with 3D simulation and multi-projector output. Listed integrations include Ableton Live, Max/MSP, Substance Designer, Notch, vvvv, OpenFrameworks, Resolume, and Unity. Communication options include OSC, MIDI, UDP, TCP, ArtNet, DMX, WebSockets, Serial, and MQTT; supported sensors include Kinect Azure, Intel RealSense, Ouster LIDAR, and Stereolabs ZED. TouchDesigner runs on Windows and macOS; current requirements list Windows 10 or 11 and macOS 13 or higher, with GPU requirements. Pricing is freemium: a free Non-Commercial license is restricted to personal, educational, or evaluation use, while listed paid plans are $300 a month for Educational, $600 a month for Commercial, and $2,200 a month for Pro.
