Installing Panda3D in Linux. General Preparation. Running your Program. A Panda3D Hello World Tutorial. Starting Panda3D. Loading the Grassy Scenery. Controlling the Camera. Loading and Animating the Panda Model. Using Intervals to move the Panda.MODELS AND ACTORS
An EGG file can contain: A Model (static geometry) An Actor (dynamic geometry) An Animation (to be applied to an actor) Both an Actor and an Animation. EGG files are created by exporting models from 3D modeling programs like Maya, Max, or Blender. Currently, the support for Maya is very strong, since the developers of Panda3D mostly useMaya.
COMMON STATE CHANGES Two of the most common changes are position and orientation. By default in Panda3D, the X axis points to the right, the Y axis is forward, and Z is up. An object’s rotation is usually described using Euler angles called Heading, Pitch, and Roll (sometimes called Yaw, Pitch, and Roll in other packages)–these specify angle rotations in degrees. MATERIALS — PANDA3D MANUAL Materials¶. Materials affect how the surfaces of models appear when lights are enabled in Panda. These have various effects such as how shiny an object appears, the brightness of it’s colors etc. Material properties are combined with textures and lighting to get the finallook of an object.

Panda3D has keyboard support built-in. Keyboard presses send Events. Each keyboard key will send an event when it is first pressed down, when it is released, and one repeatedly while it is pressed. The events can be accepted with the following code: LIGHTING — PANDA3D MANUAL So to reiterate, lighting a scene in Panda3D consists of two steps: Creating lights, and positioning them within the scene. Telling the other objects to be illuminated by the lights. Panda3D defines four different kinds of light objects: point, directional, ambient, and spotlight. Each of these is a node that should be attached somewherewithin
MULTITHREADED RENDER PIPELINE Multithreaded Render Pipeline. As of Panda3D version 1.8, Panda supports a multithreaded render pipeline for optimal performance on multiprocessor machines. If your computer has at least two CPU cores (for instance, because you have a dual-core or quad-core CPU), then you can direct Panda to utilize up to three different CPU cores forrendering

Panda3D is a 3D engine: a library of subroutines for 3D rendering and game development. The library is C++ with a set of Python bindings. Game development with Panda3D usually consists of writing a Python or C++ program that controls the Panda3D library. Panda3D was created for commercial game development and is still usedMODELS AND ACTORS
An EGG file can contain: A Model (static geometry) An Actor (dynamic geometry) An Animation (to be applied to an actor) Both an Actor and an Animation. EGG files are created by exporting models from 3D modeling programs like Maya, Max, or Blender. Currently, the support for Maya is very strong, since the developers of Panda3D mostly useMaya.
TASKS — PANDA3D MANUAL Tasks¶. Tasks are special functions that are called once each frame while your application executes. They are similar in concept to threads. However, in Panda3D, tasks are not generally separate threads; instead, all tasks are run cooperatively, one at a time, within the main thread. SAMPLE PROGRAMS IN THE DISTRIBUTION Sample Programs in the Distribution¶. The Panda3D Distribution includes quite a few sample programs. The following is a list of what’s included, and which features of the engine each sampledemonstrates.
SHADERS — PANDA3D MANUAL Panda3D supports several advanced rendering techniques such as per-pixel lighting, normal mapping, gloss mapping, glow mapping, HDR, bloom, and cartoon inking out of the box. In order to make these work, Panda is quietly uploading shaders to your video card. You don’t need to write shaders to use these features, or even know much aboutshaders.
TEXTURE — PANDA3D MANUAL The typical usage pattern is that a texture is loaded from an image file on disk, which copies its image data into system RAM; then the first time the texture is rendered its image data is copied to texture memory (actually, to the graphics API), and the system RAM NODEPATH — PANDA3D MANUAL NodePath is the fundamental system for disambiguating instances, and also provides a higher-level interface for manipulating the scene graph. A NodePath is a list of connected nodes from the root of the graph to any sub-node. Each NodePath therefore uniquely describes oneinstance of a node.
EGG SYNTAX — PANDA3D MANUAL Egg Syntax¶. The Egg Syntax. This is a condensed version of the Egg Syntax document, incorporating only syntax definitions in common use. For complete documentation, please see the Egg Syntax documentation from the Panda3D source code repository. THE 2D DISPLAY REGION The 2D Display Region. There is one more DisplayRegion that Panda normally creates automatically for the main window. This is the 2-D DisplayRegion that renders the onscreen GUI or heads-up display. It is simply another DisplayRegion that covers the entire screen, like the 3-D DisplayRegion it layers on top of, except that its camera has anMOUSE SUPPORT
Mouse Support. Panda3D has mouse support built in. In Python, the default action of the mouse is to control the camera. If you want to disable this functionality you can use the command: base.disableMouse() This function’s name is slightly misleading. It only disables the task that drives the camera around, it doesn’t disable the mouse itself.

The Panda3D Distribution includes quite a few sample programs. The following is a list of what’s included, and which features of the engine each sampledemonstrates.
BUILDING BINARIES
The build_apps command uses pip to fetch any binary packages (including Panda3D) as wheels that are necessary to build the applications for other platforms. In order for pip to know which wheels to fetch (including the correct panda3d wheel), a requirements file (or a Pipfile if pipenv is being used) is required. LIST OF PANDA3D EXECUTABLES List of Panda3D Executables. This is meant to be a list of the executables in the /bin/ folder of Panda3D. You can get a detailed synopsis of what the executables do by running them with -h as the argument. Filename. Description. bam-info.exe. Scans one or more .bam files and outputs their contents. See executable for more information. WORLDS, BODIES AND MASSES Worlds¶. To use the ODE physics system, you need to have an OdeWorld. A world is an essential component in the physics structure, it holds all your rigid bodies and joints, and controls global parameters, such as gravity, for the scene. TASKS — PANDA3D MANUAL Tasks¶. Tasks are special functions that are called once each frame while your application executes. They are similar in concept to threads. However, in Panda3D, tasks are not generally separate threads; instead, all tasks are run cooperatively, one at a time, within the main thread.LOADING MODELS
The Basics ¶. Loading static geometry is done using loader.loadModel (): The path name specified in the loadModel can be an absolute path, or a relative path. Relative is recommended. If a relative path is used, then Panda3D will search its model path to find the egg file. The model path is controlled by panda’s configuration file.MODELS AND ACTORS
An EGG file can contain: A Model (static geometry) An Actor (dynamic geometry) An Animation (to be applied to an actor) Both an Actor and an Animation. EGG files are created by exporting models from 3D modeling programs like Maya, Max, or Blender. Currently, the support for Maya is very strong, since the developers of Panda3D mostly useMaya.
DIRECT — PANDA3D MANUAL direct¶. DIRECT is a set of Python-based tools that are layered on top of core Panda3D, which is written in C++. It includes the DirectGUI tools, the task system, the Interval system, a high-level class for animated characters, and several other systems. TINTING AND RECOLORING Recoloring the Model ¶. If you wish, you can manually override the color attribute which has been specified by the model loader. nodePath.setColor(r, g, b, a) Again, this is an override.

Panda3D is a 3D engine: a library of subroutines for 3D rendering and game development. The library is C++ with a set of Python bindings. Game development with Panda3D usually consists of writing a Python or C++ program that controls the Panda3D library. Panda3D was created for commercial game development and is still used TASKS — PANDA3D MANUAL Tasks¶. Tasks are special functions that are called once each frame while your application executes. They are similar in concept to threads. However, in Panda3D, tasks are not generally separate threads; instead, all tasks are run cooperatively, one at a time, within the main thread.MODELS AND ACTORS
An EGG file can contain: A Model (static geometry) An Actor (dynamic geometry) An Animation (to be applied to an actor) Both an Actor and an Animation. EGG files are created by exporting models from 3D modeling programs like Maya, Max, or Blender. Currently, the support for Maya is very strong, since the developers of Panda3D mostly useMaya.
MATERIALS — PANDA3D MANUAL Materials¶. Materials affect how the surfaces of models appear when lights are enabled in Panda. These have various effects such as how shiny an object appears, the brightness of it’s colors etc. Material properties are combined with textures and lighting to get the finallook of an object.

In order to make these work, Panda is quietly uploading shaders to your video card. You don’t need to write shaders to use these features, or even know much aboutshaders.
BUILDING BINARIES
The build_apps command uses pip to fetch any binary packages (including Panda3D) as wheels that are necessary to build the applications for other platforms. In order for pip to know which wheels to fetch (including the correct panda3d wheel), a requirements file (or a Pipfile if pipenv is being used) is required.LOADING MODELS
The Basics ¶. Loading static geometry is done using loader.loadModel (): The path name specified in the loadModel can be an absolute path, or a relative path. Relative is recommended. If a relative path is used, then Panda3D will search its model path to find the egg file. The model path is controlled by panda’s configuration file. LIGHTING — PANDA3D MANUAL So to reiterate, lighting a scene in Panda3D consists of two steps: Creating lights, and positioning them within the scene. Telling the other objects to be illuminated by the lights. Panda3D defines four different kinds of light objects: point, directional, ambient, and spotlight. Each of these is a node that should be attached somewherewithin
WORLDS, BODIES AND MASSES Worlds¶. To use the ODE physics system, you need to have an OdeWorld. A world is an essential component in the physics structure, it holds all your rigid bodies and joints, and controls global parameters, such as gravity, for the scene.

However, in Panda3D, tasks are not generally separate threads; instead, all tasks are run cooperatively, one at a time, within the main thread. LIGHTING — PANDA3D MANUAL Colored Lights¶. All lights have a color, which is specified by light.color = (r, g, b, a).The default color is full white: light.color = (1, 1, 1, 1).The alpha component is largely irrelevant. If you are trying to simulate a natural light, it may be easier to set the color temperature instead, by calling Light.setColorTemperature() with a value in Kelvin. Use a value of 6500 for pure white MATERIALS — PANDA3D MANUAL Materials¶. Materials affect how the surfaces of models appear when lights are enabled in Panda. These have various effects such as how shiny an object appears, the brightness of it’s colors etc. Material properties are combined with textures and lighting to get the finallook of an object.

Panda uses the Filename class to store Panda-style filenames; many Panda functions expect a Filename object as a parameter. The Filename class also contains several useful methods for path manipulation and file access, as well as for converting between Windows-style filenames and Panda-style filenames; see the Filename page in the API Reference for a more complete list.

SHADERS — PANDA3D MANUAL Panda3D supports several advanced rendering techniques such as per-pixel lighting, normal mapping, gloss mapping, glow mapping, HDR, bloom, and cartoon inking out of the box. In order to make these work, Panda is quietly uploading shaders to your video card. You don’t need to write shaders to use these features, or even know much aboutshaders.
LIST OF ALL CONFIG VARIABLES List of All Config Variables. The following is an incomplete list of config variables as of June 2020, using Panda3D 1.10.4.1. Some, but not all, variables were generated using this code: Bear in mind that this list includes configuration parameters that control functionality that isn’t fully implemented yet. SAMPLE PROGRAMS IN THE DISTRIBUTION Sample Programs in the Distribution¶. The Panda3D Distribution includes quite a few sample programs. The following is a list of what’s included, and which features of the engine each sampledemonstrates.
BUILT-IN GLOBAL VARIABLES Built-in Global Variables¶. When an instance of the ShowBase class is created, many of its member variables are written to the built-in scope of the Python interpreter, making them available to any Python module without the need for extra imports.. While these are handy for prototyping, we do not recommend using them in bigger projects as it can make the code confusing to read to other Python DIRECT — PANDA3D MANUAL direct¶. DIRECT is a set of Python-based tools that are layered on top of core Panda3D, which is written in C++. It includes the DirectGUI tools, the task system, the Interval system, a high-level class for animated characters, and several other systems.BUILDING BINARIES
The build_apps command uses pip to fetch any binary packages (including Panda3D) as wheels that are necessary to build the applications for other platforms. In order for pip to know which wheels to fetch (including the correct panda3d wheel), a requirements file (or a Pipfile if pipenv is being used) is required. LIGHTING — PANDA3D MANUAL So to reiterate, lighting a scene in Panda3D consists of two steps: Creating lights, and positioning them within the scene. Telling the other objects to be illuminated by the lights. Panda3D defines four different kinds of light objects: point, directional, ambient, and spotlight. Each of these is a node that should be attached somewherewithin
