Panda3D vs Blender

The liberal license allows use of the engine for any purpose without restrictions or royalties.

Although it's possible to use only C++ to program in Panda3D, all its power is available to the Python scripting language, while not trading in performance since the performance-critical parts are implemented in C++.

It has a powerful binding layer that exposes the vast majority of the API via Python-based interfaces.

Panda3D has in-depth integration with industry standard physics engines such as Bullet, NVIDIA PhysX and ODE, but also offers a simpler built-in physics engines that will cover more basic needs.

Creating weird world constructs is generally a breeze. The node system the engine runs with allows to build self-looping worlds and, on large scale, non-Euclidean scenes without having to introduce a huge amount of custom code.

Panda3D has a suite of powerful tools to help track down performance bottlenecks, memory leaks and examine internal state.

Panda3D offers web plug-ins that allow deployment of an application to all major browsers. A WebGL port is in the works as well.

Blender is licensed under the GPL. Some Blender modules such as the Cycles rendering engine are licensed under the Apache 2.0 license.

Support lots of modern 3D formats including DAE and FBX - ideal for game developers.

Blender runs the Cycles path tracing engine under the hood. Cycles is a very powerful rendering engine capable of full path tracing (light fall off, caustics, volumetrics). It is mostly compatible with OpenCL and CUDA rendering, and is implementing mycropolygon displacement features. The upcoming release has a viewport engine called EEVEE whereby you can see and interact with your work in render mode in real time!

Blender embeds Python 3, which can be used to write add-ons, tools, extend the interface, rig characters and automate tasks.

Blender provides a full rigging system, and automates animation by interpolating between keyframe positions.

Releases are made every ~3 months.

Although Blender's 3d painting and sculpting tools (mostly painting) are not at par with specialized software like Substance Painter, ZBrush, or Mari, it is more than capable of getting most jobs done if the user takes the time to learn and understand it.

Blender's node-based compositor has comprehensive video sequencing and post-processing features.

Good keyboard shortcuts for everything. Keep your left hand on the keyboard and your right hand on the mouse.

It offers a round solution (it covers many areas and professional fields) for a freelancer, for free, constantly updated, very polished, and allowing high quality results that clients do require. After some learning, it becomes very useful for professional work.

There's a huge community to help you get started immediately.

The trick with Blender is to get used to its usage philosophy, as it keeps consistent through all the application. Once you get it, every feature or addition is learnt naturally, almost effortlessly.

You don't have to switch between software when you want to do different things. Because modeling, sculpting, composting, video editing etc can all be done in blender.
