The simplest way to click on 3D objects in Panda3D is to use very simplistic collision detection coupled with event processing. First, after a CollisionTraverser and a CollisionHandler have been set up, attach a CollisionRay node to the camera.

Panda3D is an open-source, free-to-use 3D engine made for the development of realtime 3D games, visualizations, simulations, experiments — you name it! It consists of a library of subroutines that can be used with either the Python or C++ programming language, as well as a few tools to assist with development and debugging.

The Panda3D Python API consists of two packages: the panda3d core library, which is written in C++, and the direct library, which is written in Python. This section of the documentation aims to give a complete overview of all the classes and functions defined in these two libraries.

In the context on Panda3D, this is a viable way to share texture and vertex data with non-Panda3D modules. Features demonstrated: (gizeh_to_panda3d.py) Creating images on a canvas backed by a numpy array (which is the standard way of storing images in Python), and copying it into a Panda3D texture.

Jul 25, 2013 · Panda uses Euler angles (aka flight angles) to represent rotation. The angles passed to setHpr are yaw-pitch-roll angles (in degrees), except that Panda uses the term "heading" instead of "yaw" because the letter Y is already used for the Y position.

Dec 2, 2024 · Panda3D is an excellent tool for creating 3D graphics and games with Python. It’s easy to use, and with just a few lines of code, you can create stunning 3D scenes. Whether you’re building simple projects or large-scale games, Panda3D provides all the tools you need to bring your ideas to life.

You can in fact load .obj model files in Panda3D, starting from version 1.10. Just add load-file-type p3assimp to your config.prc file in the etc folder of your Panda3D installation, and you can then load .obj models using model = self.loader.load_model("my_model.obj") .

Sep 7, 2011 · I have managed to successfully detect when I click on a model (with a collision ray colliding against the model geom), but I couldn’t find a way to relate the collision entry information with the Player class object.

List all of Panda3D’s broad capabilities, Help you understand what purpose these serve, Give you a general understanding of how to build games in Panda3D. In time, though, you will need to supplement the knowledge provided by this manual by studying the Reference Section.

You can calculate the transformation from an object to the camera using nodepath.get_transform(base.cam), which is a TransformState object that you may optionally convert into a matrix using ts.get_mat(). This is surprisingly fast, since Panda maintains a composition cache for transformations so that this doesn't have to happen multiple times.
