With the popularity of android in the world, more and more people are focusing on mobile devices equipped with android. However, due to the limitations of handheld devices, how can we use limited resources to achieve a good experience, this is an issue that must be considered by the device manufacturer. The dazzling interface is a way to increase user experience. Among them, the 3D effect is undoubtedly the most attractive and persuasive to users. The 3D engine can greatly save the cost of 3D development. Therefore, after a survey, the engine of this survey must meet the following requirements:

 

Open-source: easy to change code, optimize performance, and free of charge. (The business engine is better, isn't it ?) Support for OpenGL: DirectX can only be used on windows platforms and can be transplanted to Android: It must be supported for Android platforms with relatively high efficiency: Limitations of mobile devices, such as power, CPU, A total of nine engines are available for the results of current surveys such as GPU, which will be shared with you to save your investigation time (more engines are found during the investigation, but 9 types are selected by individuals): Horde3D OGRE3D Irrlicht jmonkey Catcake jPCT-AE min3d gamine Alien3D Perform Parameter Analysis for nine engines:1, OGRE

Name	OGRE
Supported Graphic lib	OpenGL and Direct3D
Develop Language	C ++, builds on gcc 3 + on Linux
Description	A powerful real-time graphics engine. At present, it is best to use the most widely used Free Open Source engine in the world, which is comparable to the commercial engine.
Merit	Supports multiple texture image formats, including PNG, TGA, DDS, TIF, GIF, and JPG. Supports bone animation and built-in powerful material management and script systems, material maintenance can be performed without a line of code, and visual editing tools are available. Complete documentation.
Defect	Relatively difficult to get started, low rendering efficiency. Focus only on graphics, excluding sound, network, and other modules, but with Interfaces. If necessary, you can add third-party plug-in libraries, such as physical libraries and audio libraries, for combined development.

 

 

2. Irrlicht

Name	Irrlicht
Supported Graphic lib	OpenGL and Direct3D
Develop Language	C ++
Description	The famous "ghost engine"
Merit	Quick Start, easy-to-use, and fast running. It provides dynamic shadows, particle systems, role animation, indoor and outdoor technologies, and Collision Detection on commercial 3D engines. There are many Irrlicht enhancement programs on the network for use.
Defect	Insufficient support for BSP

3. jmonkey

Name	Jmonkey
Supported Graphic lib	OpenGL and Direct3D
Develop Language	Java
Description	JMonkey 3D is a java 3D engine.
Merit	It encapsulates OpenGL and provides a full-performance toolkit, including image decoders, file decoders, GUI systems, particle systems, physical systems, and lighting systems. It provides complete functions.
Defect	JME is too good for OPENGL encapsulation, so it cannot find traces of GL at all, and many underlying optimizations cannot be modified. Currently, only opengl es 2.0 is supported.

4,Catcake

Name	Catcake
Supported Graphic lib	OpenGL
Develop Language	C ++, java
Description	Catcake is a cross-platform Java 3D graphics engine. It also has the C ++ version.
Merit	It has a dedicated android version, which provides excellent performance in ease of use and running performance. Supports audio processing and video playback.
Defect	Insufficient documentation

5,JPCT-AE

Name	JPCT-AE
Supported Graphic lib	OpenGL
Develop Language	Java
Description	JPCT-AE is a transplanted version of jPCT on the Android platform. It is based on the java language.
Merit	Small Size, dedicated Android porting version, with amazing Downward compatibility, can run in JVM1.1 environment, because the graphic rendering interface provided by jPCT completely complies with all Java 1.1 specifications.
Defect	Java writing, efficiency to be considered

6,Horde3D

Name	Horde3D
Supported Graphic lib	OpenGL
Develop Language	C ++
Description	Horde3D is a small open source 3D rendering engine
Merit	Simple and easy to understand. It comes with a scenario editor that integrates simple model editing, particle editing, and action editing functions.
Defect	Inefficient

7,Min3D

Name	Min3D
Supported Graphic lib	OpenGL
Develop Language	Java
Description	Lightweight 3d library/framework for Android using Java with OpenGL ES targeting compatibility with Android v1.5/OpenGL ES 1.0 and higher.
Merit	The dedicated android 3d UI engine is very small, with only a few hundred kb. Based on opengl es 1.x, it encapsulates some basic drawing operations of opengl, as well as drawing management and rendering operations. Provides an activity class RenderActivity, which is easy to use.
Defect	Features are relatively simple.

8,Gamine

Name	Gamine
Supported Graphic lib	OpenGL
Develop Language	Java
Description	A small java 3D Engine
Merit	Dedicated engine for Android, small size, easy to investigate
Defect	Low Efficiency

9. Alien 3D

Name	Alien 3D
Supported Graphic lib	OpenGL
Develop Language	Java
Description	3D Game Engine of OpenGL ES interface written in java
Merit	3DS loading, 2D particle, prototype plugin, tiled map, and genie Animation
Defect	Too few research materials

 

The above lists the engine introduction, advantages and disadvantages, and so on. You can choose based on your own needs and focus. Among them, OGRE and Irrlicht are relatively mature products, it is an open-source 3D engine that is widely used and has many documents and experience on the Internet. In addition, the engine selection has two important points: 1. Efficiency, whether the algorithm is good enough; 2. whether the effect is good enough to achieve the brilliant effect you want, and whether the Sawtooth effect is serious, whether it is fresh during running.

The following describes two engines for comparison..

 

 

	OGRE	Irrlicht
Development language	C ++	C ++
Ease of use	High threshold	Easy to understand, low entry level
Efficiency	Slow opgl Rendering	Relatively high
Beautiful	The rendering effect is good and clear, Good visual effect	Smooth motion and good visual effects
Materials	Many, widely studied and transplanted, There are many projects and experiences for Reference	Comprehensive, many successful open-source projects and experiences
Portability	Reference material migration required	Dedicated Android version, simple porting
Usage	Very mature, free 3D graphics engine Highest rating and wide usage	Mature engines with high usage
Texture format and scene format	LPNG, JPEG, TGA, BMPl3D Max, Maya, Blender	L PSD, JPG, PNG, TGA, BMPl3DS, OBJ, MY3D, CSM, DAE, DMF, MS3D, LMTS, MD2

You are welcome to learn from and supplement it. We would like to remind you that you should pay attention to the open protocols of these 3D engines to avoid inconvenience.
