conversion; animation-free files can be exported using the latest blender, which has no obvious advantages. However, because you are not familiar with the blender API, the blender API has been significantly modified in version 2.5, so the export scripts or functional scripts of the two versions cannot be converted to each other. The following is my current scrip

The model used by WebGL is built in 3D modeling software, so how do these 3D models be exported for Three.js engine calls?
Three.js supports multiple formats of 3D files, such as Collada (. Dae) files, such as Three.js JSON-formatted files. SketchUp, CINEMA 4D These software natively support the export of model files to Collada format files, 3ds Max, Maya can install Opencollada plug-ins (https://github.com/KhronosGroup/ Opencollada/wiki/opencollada-tools) Allow yourself to export the Collada fi
If you are looking for free and cool graphics design software for your UbuntuLinux operating system, you are right here! This time, we will introduce you to the extensive and free 3D graphic design software Blender. Blender is a free and open source 3D model creation software. It is not only applicable to Linux platforms, but also runs on other mainstream operating systems. Next let's take a look at the use
Say we have a latest Blender extracted from the download package. We want to create a launcher in Blender so that we can start it from the Unity Dash or App Menu.Press ctrl+alt+t to open terminal. When it opens, Run command to create . Desktop file and edit it with Gedit text editor:/usr/share/applications/blender-2.7.desktopWhen the file opens, paste below into
Ubuntu10.04 is a stable version of v2.49 in the software library, but blender has made great changes in Versions later than v2.5. The official website provides Binary Package downloading of v2.5, but there is always a crash problem on Ubuntu10.04, so I want to compile it from the original code. 1. install the software package required by blenderv2.5 $ sudoaptitudeinstall \ python3.1-dev \ scons \ subversion
The software library of Ubuntu 10.04 is a s
Another 3D adventure game under Ubuntu is available. The Blender Foundation has recently released the open-source 3D Game YoFrankie. However, it is difficult for me to try it out, and I cannot beat the second level, see the Blender Foundation's OpenGame project, development code ProjectApricot, and three Blender artists, A development team composed of two Crystal
This article provides a detailed analysis of the php ascii code conversion class. For more information, see
The code is as follows:
Class ascii

Function decode ($ str)
{
Preg_match_all ("/(d {2, 5})/", $ str, $ );
$ A = $ a [0];
Foreach ($ a as $ dec)
{
If ($ dec {
$ Utf. = chr ($ dec );
}
Else if ($ dec {
$ Utf. = chr (192 + ($ dec-($ dec % 64)/64 ));
$ Utf. = chr (128 + ($ dec % 64 ));
}
Else
{
$ Utf. = chr (224 + ($ dec-($ dec % 4096)/4096 ));
$ Utf. = chr (128 + ($ dec % 4096)-($ dec % 64
