ios:显示带有GLEssentials示例代码的简单3D模型 [英] ios : Displaying a simple 3D model with GLEssentials sample code

问题描述

我的目标是显示一个简单的3D模型并在其上应用纹理.

My goal is to display a simple 3D model and apply a texture on it.

我已经下载了GLEssentials

I've downloaded the GLEssentials ios sample project to learn how to develop this (i'm new in ios OpenGL-ES API)

但是示例模型是一个.model文件，我从未听说过，也从未出现在

But the example model is a .model file, which I never heard about and which never appear in model bank websites.

1. 这种文件是什么?
2. 示例代码是否与其他常见模型类型(.obj，.c2d，.3ds)兼容?
3. 从这个项目开始是个好主意吗?

推荐答案

看看这个问题:

• 如何将Blender blend(或obj)文件转换为Qualcom Vuforia .h文件

在我的答案中，我描述了一个脚本和随附的Xcode项目，该项目将.obj/.mtl文件转换为适用于iOS上的OpenGL ES的头文件

In my answer, I describe a script and accompanying Xcode project that converts .obj/.mtl files to header files suitable for OpenGL ES on iOS [link].

针对您的问题:

1. 我相信.model文件仅适用于示例项目，并且是Apple专有的扩展名.它很可能包含诸如顶点位置之类的简单数据.
2. 我认为您很难使其他模型类型适合示例代码，这对于OpenGL ES初学者来说非常复杂.您可能想在Cocos2D上的.pod文件中查看此处.我已经看到并听到了很多很棒的事情.
3. 我不推荐它:)

1. I believe the .model file is only appropriate for the sample project and is a proprietary Apple extension. It most likely contains simple data such as vertex positions.
2. I think you'd struggle to fit other model types into the sample code, which is very complex for OpenGL ES beginners. You might want to have a look at .pod files on Cocos2D here. I've seen and heard great things about it.
3. I wouldn't recommend it :)
