Blender is a free and open-source software that allows you to create a wide range of 2D and 3D content. You can create 3D models, water simulation, animation, rendering, particles, and other computer simulations, non-linear video editing and creating interactive 3D applications. You also get a lot of free help from the online community, as well as viewing some tutorials that help you with your new projects. Once the program is started you do not have to set anything, I mean the arrangement of tools, everything appears in the work window so it is easy to create without wasting time searching for those tools. You can customize your themes in the settings menu by modifying them by using the scripts created with the Python programming language. Like any rendering program, it requires a powerful processor, because during rendering it is used at full capacity.
