Imagine by Impulse (1990) was one of the most powerful 3D rendering programs on the Amiga. It offered polygon modeling, spline-based objects, texture mapping, raytracing, radiosity, and animation creation. Imagine 4.0 was the last Amiga version. It competed with LightWave 3D and Cinema 4D and was used by many Amiga artists for 3D graphics and animations.
