3D models are widely used anywhere in 3D graphics and CAD. Their use predates the widespread use of 3D graphics on personal computers. Many computer games used pre-rendered images of 3D models as sprites before computers could render them in real-time.
Sketchup is a 3D modeling software and extremely easy to learn as well as fun to use. Sketchup is incredibly a strong substitute of AutoCAD for architectural 3d modeling and design. Designing and modeling virtual exterior and interior design, architectural diagram and flowchart design, and 3D modeling is my expertise in Sketchup.
Blender is a professional, free and open-source 3D computer graphics software tool-set used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games. Blender’s features include 3D modeling, UV unwrapping, texturing, raster graphics editing, rigging and skinning, fluid and smoke simulation, particle simulation, soft body simulation, sculpting, animating, match moving, camera tracking, rendering, motion graphics, video editing, and compositing.
