带 Flex 的 Papervision 3D

发布于 2024-07-24 12:05:07 字数 89 浏览 8 评论 0原文

我是 Papervision 的新手。我想设计一个球体，周围有 8 个孔其直径。我该怎么做？如何在 Papervision 中的球体上绘制任何内容？

取决于您想要孔的外观。您可以在任何 3D 编辑器中制作一个带有孔的整体。 Blender、wings 3d、sketchup 都是免费的，并且可以以 papervision 支持的格式导出。

如果您想在球体上绘图，则意味着您想创建并应用纹理。您可能想尝试使用凹凸贴图来获得一点真实感，但对于 npw，仅应用材质就是一个好的开始。

最简单的方法是应用位图或影片材质。顾名思义，位图材质只是位图，而影片材质是由影片剪辑制作的材质。
据我所知，位图材质有 3 种类型：

BitmapMaterial - 您在其构造函数中传递 BitmapData 实例
BitmapFileMaterial - 将路径传递给外部图像文件
BitmapAssetMaterial - 您从库中传递位图的链接名称。

MovieMaterial 有 2 个版本：简单的 MovieMaterial，您在其构造函数和 MovieAssetMaterial 中传入对 DisplayObject 的引用。您通过了 Linkage Class 集
对于库中的影片剪辑。还有一个 MovieCacheMaterial，但我认为您不需要它。

所以这里是一个关于如何向球体添加纹理的基本示例，假设您的场景称为场景：

//assuming BMP8holes is a linkage for a Bitmap in the library
var ballBitmapMaterial:BitmapAssetMaterial = new BitmapAssetMaterial("BMP8holes");
//assuming Movie8holes is a linkage a MovieClip in the library
var ballMovieMaterial:MovieAssetMaterial = new MovieAssetMaterial("Movie8holes");

var ball:Sphere = new Sphere(ballBitmapMaterial);
scene.addChild(ball);

球体参考（无论如何……pv3d文档）在这里：http://papervision3d.googlecode.com/svn/trunk/ as3/trunk/docs/org/papervision3d/objects/primitives/Sphere.html

希望这有帮助。

Depends on how you want the holes to look like. You could just make a wholes with holes in it in any 3d editor. Blender and wings 3d , sketchup are free and can export in papervision supported formats.

If you want to draw on a sphere, it means you want to create and apply a texture. You might want to try using a BumpMap for a bit of realism, but for npw, just a applying a material is a good start.

The simplest way is to apply a Bitmap or MovieMaterial. A Bitmap Material is just a Bitmap, as the name implies and a MovieMaterial is a material made from a MovieClip.
There are 3 flavours of Bitmap materials as far as I know:

BitmapMaterial - you pass a BitmapData instance in it's constructor
BitmapFileMaterial - you pass the path to a an external image file
BitmapAssetMaterial - you pass the linkage name of a bitmap from the library.

MovieMaterial has 2 version: simple MovieMaterial, you pass in a reference to a DisplayObject in it's constructor and MovieAssetMaterial. You pass the Linkage Class set
for a MovieClip in the Library. There is also a MovieCacheMaterial, but I don't think you'll need it for this.

so here is a basic example on how you add a texture to a sphere, assuming your scene is called scene:

//assuming BMP8holes is a linkage for a Bitmap in the library
var ballBitmapMaterial:BitmapAssetMaterial = new BitmapAssetMaterial("BMP8holes");
//assuming Movie8holes is a linkage a MovieClip in the library
var ballMovieMaterial:MovieAssetMaterial = new MovieAssetMaterial("Movie8holes");

var ball:Sphere = new Sphere(ballBitmapMaterial);
scene.addChild(ball);

Sphere reference ( well...pv3d docs anyway) here: http://papervision3d.googlecode.com/svn/trunk/as3/trunk/docs/org/papervision3d/objects/primitives/Sphere.html

Hope this helps.
